Stockholm Blog #11: Beyond GrowSmarter — what is ahead in Stockholm

We have less than two months left of the GrowSmarter project and it is time to look ahead. When we started the project, Stockholm was already growing fast and needed smart solutions for the growth to be sustainable. This growth has only accelerated and 140 000 new apartments and 280 000 new inhabitants are expected by 2030. Combined with the goal of becoming fossil-fuel free in 2040 Stockholm faces some challenges, but are there answers to find in the GrowSmarter project?

Actually, there are. Quite many indeed.

Better use of urban space

One of the first issues of growth is the use of land and city space. We need to use urban space very wisely. Let’s start with waste. What space is necessary for different waste handling methods. The numbers below are from a Swedish study where a waste collection system sorting into three fractions for 1700 households was evaluated:

  Waste collection and land use per household Waste collection land use for 140 000 new apartments
Conventional bin system 0,93 m² 130 000 m²
Conventional automated waste collection system 0,17 m² 24 000 m²

Then we have Envac’s smart waste handling system in Valla Torg. It is collecting 4 fractions, but all in one and the same inlet depositing into one terminal (container). So we collect four fractions and use one third of the space of the conventional AWCS evaluated above. This means that we use less than 0,06 square meters of land per household which would “only” total 8 000 square meters for all new inhabitants expected in Stockholm. Stockholmshem, the housing company, is currently building 160 new apartments near Envac’s smart waste system, and they only need to install the inlets as the terminal can easily handle the waste from these new households.

The same principle applies to the green parking index. The electrical car and cargo bike pool can provide mobility services to inhabitants using only a fraction of the space needed by private cars. Already deployed in Valla Torg, these mobility solutions are also available for the 160 new households thus minimising the need for parking space in the new buildings. This saved parking space alone can pay the additional costs of these mobility services. These are two great examples of smart sustainable solutions which also helps a growing city using its valuable space wisely.

Re-using and storing power

We also need to heat up these 140 000 new apartments. In Stockholm, most buildings are connected to the district heating system. Stockholm Exergi has proved in GrowSmarter that waste heat from data centers or supermarkets can heat up buildings. In 2018 these and other waste heat sources heated up 31 000 apartments. The ongoing installations alone can heat up an additional 27 000 apartments in Stockholm. That means almost 60 000 apartments are heated up with heat that used to go to waste. With the expansion of data centers in Sweden it is not a far-fetched idea that all the 140 000 apartments could be heated with waste heat from data centers. There are data center providers which build their data centers under ground, thus not taking valuable space above ground, but still providing waste heat to the district heating system.

smarter.eu/fileadmin/editor-upload/Blogs/_12/M6.1_Open_district_heating.png" alt="Waste heat recovery from data center. Photo: Stockholms Exergi" width="801" height="559" />

 

Stockholm still needs to reduce the need for heat in buildings. Skanska showed together with Stockholmshem and L&T that it is possible to reduce the energy need in existing buildings up to 75%. On a larger scale, Stockholmshem found, it is economically feasible to reduce energy use in existing buildings with the solutions installed in Valla Torg by 50%. Combining waste heat recovery with energy efficient refurbishment is one approach that could help Stockholm phase out the last coal and oil used in district heating well before 2030.

Stockholm, as many other cities, is facing an increased electrification. More data is processed, or should I say more and more videos are uploaded, shared and streamed, which demands more data centers. Data centers already consume as much electricity as the UK and this is rapidly increasing. In addition we have the electrification of vehicles and the use of heat pumps also demand electricity. We need to consider that Sweden is phasing out nuclear power, which means that we will be more dependent on renewable energy sources. As the sun doesn’t shine and the wind doesn’t blow all the time, we need electricity storages more in the future than now. L&T has combined photovoltaics, smart electricity management and battery storage in commercial, residential and office buildings in GrowSmarter. Even if battery storage currently is not economically feasible it will be increasingly so in the future. Battery storage can be used in two ways. In summer you store the overproduction of solar electricity there and in winter you cut electricity effect peaks with the storage. The latter is already done now, but will be even more important in the future. The results from the private condominium Årstakrönet where L&T has managed these solutions is very promising as the amount of electricity from the grid could be reduced with more than 30% with these and electricity saving measures. Peak loads have also been shaved and the three phases are no longer running a risk of being overloaded for instance when electrical vehicles are charged.

Streetlights are also abundant in Stockholm with more than 150 000 of them all running on electrictiy. The smart street lights installed show that electricity can be reduced between 20-45% compared to traditional LED-lights. The Traffic Department of Stockholm is now working to find the best solution and open platform to upscale the solutions and are testing this in Stockholm.Lastly the increased population will mean more people and more goods on the streets of Stockholm. As we do not have the space or possibility to build new streets and roads, we need to use the existing infrastructure in a much more efficient way.

Smarter solutions for a connected city

The construction logistics center implemented by Carrier is one such solution. When the construction material needed the day after is transported to the construction site the evening before, we can move these transports from times with a lot of traffic to times with less traffic. The waste can also be collected at the site with the returning transport in the evening. The overall traffic to the construction site will also decrease with the construction logistics center and these transports can be made with vehicles using biofuels as was done by Carrier. Considering that 140 000 apartments need to be built, the amount of construction material traffic will be high the next ten years and it will be important to implement this type of solution widely in the city. Interestingly, studies show that of the heavy transports in a city almost 30% are waste transports. The Envac waste solution mentioned above not only needs less space, but also reduced waste transports in the area with 90%.

smarter.eu/fileadmin/editor-upload/Blogs/_12/001Smart_city.png" alt="Smart Connected steeet environment is key for controlling flows in the smart City. Photo: IMB" width="801" height="463" />

Sensor technology, connectivity, big data combined with artificial intelligence are means by which the city better can manage traffic flows in a city. In the Slakthus-area, the city together with IBM can show traffic flows of vehicles, pedestrians and bicyclists in real time. We can predict congestion, we can understand how weather or different type of events correlate with people and traffic flows in the streets. We can use this information to guide people to transport themselves to and from the area in a sustainable, yet faster, way. As the Slakthus-area will be a large construction site the coming 10 years this information is essential to understand how construction transports, goods transports, event visitor traffic and other traffic can be managed in the often narrow streets. The new subway station will for instance guide a very large flow of people into Rökerigatan, which will be a main commercial street in the area. This street will not have separate pavements or bike lanes, so all modes of traffic needs to share the same street. By predictive flow analysis, especially regarding events, it is possible to manage goods transports and deliveries, so that they do not collide with people going to events.

If this sounds at all interesting I do welcome you to come to the final conference on December 3rd, where all these solutions will be showed as part of the study visit programme.

Do register yourself as fast as possible as places are limited. You can read more and register on GrowSmarter's website.

Cologne Blog #11: Sharing the Smart Solutions

In the past five years, the GrowSmarter partners in Cologne have achieved great results in the three different areas of the project: Low Energy Districts, Integrated Infrastructures and Sustainable Urban Mobility. Now we are working hard to ensure upscaling becomes possible in Cologne and that other cities can benefit from our efforts and replicate the smart city solutions we have implemented.

To this effect, we organized several study visits and numerous events to regularly educate groups of visitors from universities and cities from within Germany, Europe and abroad. The partners of GrowSmarter got a first taste of that work, when they visited Cologne for our General Assembly over the summer.

Action Area 1: Low Energy Districts

During the General Assembly we took our partners on a tour to experience our work in Low Energy Districts for themselves. The scene was the GrowSmarter project area Mülheim (Stegerwaldsiedlung), where we have implemented a large-scale energy efficient refurbishment of 16 building blocks to lower their CO2 emissions and upgrade them for our citizens to live in. Noticeable results from this work done by our partners include an average CO2 reduction of 72% in the Stegerwaldsiedlung neighborhood.

Our partner, the German utility RheinEnergie, also installed photovoltaic cells on top of buildings in the neighbourhood, and is exploiting that energy to make the Stegerwaldsiedlung more self-sufficient. In order to achieve this, they implemented the so-called Siedlungsmanagement software which makes it possible to plan energy use in a much more efficient manner through the entire neighbourhood.

smarter.eu/fileadmin/editor-upload/Blogs/_12/ Stegerwalds.png" alt="Stgerwaldsiedlung" width="801" height="559" />

Action Area 2: Integrated infrastructures

Under the theme Integrated Infrastructures, we have focused on two different, albeit connected, approaches. On the ground in Cologne, on the so-called “Klimastraße”, which is part of the initiative ‘SmartCity Cologne’ where RheinEnergie tests innovative technologies, the company integrated three electric charging points electric vehicles in lampposts on the street. These three charging points have a yearly loading volume of 14.000 kWh and in one year of implementation they reduced the CO2 emmissions by ten tonnes compared to if the same transportation had been done in regular cars.

The second approach is related to Big Data and the work done by [ui!] - the urban institute with its open urban big data platform called ‘Urban Pulse’. The platform is able to store and process urban data in real-time in order integrate a wide range of different data and services used by Cologne (and other cities when the solution is replicated!). Data can be shared from different departments of a city administration as well as from different utilities or third parties with relevant data. The data platform gives a fast and easy overview of the current situation of the city. Different focal areas such as the environment or traffic can be considered. Three factsheets explaining the different use-cases of the Urban Pulse were recently made and you can find them online at the GrowSmarter website:

Action Area 3: Sustainable Urban Mobility

Finally, we showed our partners visiting from the rest of the GrowSmarter cities some of the implementations we have done to improve Urban mobility in Cologne as part of the project. A centrepiece of this work is the Mobility Stations. A mobility station offers multiple transport alternatives at one location. The mobility stations can vary in both size and type of location, and ten different stations were implemented in or near the neighbourhood of Mülheim. Some offer e-bike and e-car sharing, while others may offer public transportation in connection to parking and the availability of e-bikes.

In total, together with our partners, RheinEnergie, Cambio Cologne, KVB and Ampido, we have deployed 54 different e-vehicles in Cologne (cars and bikes) in the different mobility stations. As mentioned in earlier blogs, the process for signing up for an e-bike is simple. The costumer can sign up for free by using the homepage www.kvb-rad.de, by using the KVB or nextbike App or register on the phone by using the nextbike costumer hotline.

 

smarter.eu/fileadmin/editor-upload/Blogs/_12/GS_Stegerwald_Mstation2@kvb.png" alt="A Mobility Station at Stegerwaldsiedlung. Photo: KVB" width="801" height="601" />

Our partners from KVB and cambio have described their work with the Mobility Station in an independent blog Segment:

Mobility station, e-bikes and the new design guide - by the industrial partners KVB and cambio

Within the project of GrowSmarter, in particular for the mobility stations, all technical requirements e.g. the certifications of safety and quality of the products, have been completed. For the commission of the e-bikes a test called "Inbetriebnahmeprüfung" by the the German Technical Inspection Association was necessary. The KVB is the first company, who realized this test of an e-bike station in Germany.

Since the 8th of Februar all e-bikes are in use. Because of the many unauthorized returns of the e-bikes outside the mobililty stations, the KVB had to develop a new design for the e-bikes to ensure the customers understand the difference between an e-bike and a conventional bike. These difference refer to the pricing system and the regulations of returning and renting the e-bikes.

smarter.eu/fileadmin/editor-upload/Blogs/_12/ EBike.png" alt="" width="300" height="173" />

The Verkehrsverbund Rhein-Sieg developed a new design guide for the signature of mobility stations in Nord Rhine-Westfalia. Together with the city council of Cologne and cambio carsharing a new concept for the pedestrian signs between the light rail- and bus stations and the mobility stations had to be installed.

Furthermore there has been an enourmous sharing and discussion of information and experience especially for the members of WP4 during the general assemblies in Barcelona and Porto. In addition to the GA´s there has been a webinar concerning urban mobility which was presented by Tanya Bullmann (cambio CarSharing) and Thomas Bischof (KVB). There have also been many interviews regarding the GrowSmarter project and the development of smart mobility. These requests from students and universities have been answered from nearly all team members of WP 4.

In order to increase the use of the offered electric car-sharing, cambio started so called „E-Infoveranstaltungen“. These are best described as a meet & greet between cambio staff and customers or car-sharing interested people directly at the mobility stations during weekends. Every weekend, cambio met customers at a different station in order to explain the usage of the electric vehicles and lower the threshold for use. The meetings turned out to be very successful and each was visited by at least 15 up to 50 people. Customers were asking cambio staff questions and exchanged experiences. In the weeks after each current meeting we could see an increased use of e-vehicles at the mobility stations.

Cologne Blog #9: Making the smart city available - Smart home systems and Open Urban platforms

Our smart district is producing a lot of information. Our “SmartHome GrowSmarter” research study for example will look at the feedback that the volunteer tenants will give from the use of Smart systems in their energetically renovated houses. Open Urban Platforms such as the one developed in GrowSmarter, including our Urban cockpit, is becoming a reference for smart cities. 

 

Action Area 2 - Low Energy Districts: SmartHome Systems in the Stegerwaldsiedlung

RheinEnergie found a manufacturer (homee) who is going to equip the Smart Home system with an interface that enables AGT to collect and measure the required data. The aim of the study is to investigate the impact of Smart Home systems on users' quality of life and potential energy savings.

Every tenant who lives in one of the 16 energetically renovated houses can apply to participate in the “SmartHome GrowSmarter” research study. RheinEnergie offers to install up to 50 free systems. Participants will receive a SmartHome system worth approx. 1.000€ (including installation) which they can keep after the end of the study.participants must agree to share their experiences in surveys which will be sent out at least quarterly.  The data will be evaluated anonymously and confidentially by the technical university of Cologne (TH Köln).

With the SmartHome system provided, tenants have an open system that can combine different radio protocols and components from many different manufacturers to set up individual SmartHome systems. The research study decided to use the radio protocol Z-Wave. The tenants received the homee base cube, the Z-Wave radio cube and various matching components, such as the smart heating thermostat, window and door sensors and smart plugs to measure the electricity consumption. The base cube collects information, processes it and stores it locally. It acts as the central control over the smart components. A Wi-Fi connection allows the control of the connected devices via smartphone or PC. To connect more sensors or actors you can add more cubes to the brain cube which support other Smart Home radio protocols like Z-Wave, Zigbee or EnOcean.

The Smart Home system allows a comfortable control of lights, heating, etc. via Smartphone from any room. You can, for example, check that all windows are closed while being away from home.

At both informational events on March 24th 2018 and on May 17th 2018, the project partners RheinEnergie (with the TH Köln) and AGT had a display wall to explain the system and the extra components to the tenants and show them its advantages.

Action Area 3 - Integrated Infrastructure: Open urban Platforms as key component for integrated SmartCity infrastructures

The European Innovation Partnership for Smart Cities and Communities (EIP-SCC) exists since 2013 and now has more than 5,000 affiliates in over 31 countries. The EIP-SCC discusses central questions of the Smart Spatial Development. A central finding of the Cluster “Integrated Infrastructures & Processes”[1] is the need for open urban platforms prerequisite for the rapid implementation of intelligent solutions in the cities that can be used by the various actors in a city. The first step in this direction has been made by the Urban Platforms initiative, which comprises three areas: the demand side, which is mainly represented by cities, the supplier side, and the standardization.

With a Memorandum of Understanding (MoU) smartcities.eu/search?keywords=Towards+Open+Urban+Platforms+for+Smart+Cities+and+Communities&op=Search&form_build_id=form-dkGfZmSe05Z3AkPTSL0NcETMiWhb4l5L_iZaCeBRKNg&form_id=smart_cities_search_block_form">“Towards Open Urban Platforms for Smart Cities and Communities”, the initiative aims to provide broad support from the industry for the implementation of open solutions. Currently, 44 companies from the industry have signed the memorandum. On the demand side, a declaration of intent has been signed by the 24 cities and two city networks, which will help to develop the core requirements for open, urban platforms.

[ui!]UrbanPulse is one of the first urban platforms that has been aligned to the reference architecture of the MoU and thus the open urban data platform of Cologne according to GrowSmarter's “Integrated Infrastructure” measure “8.1 Big consolidated open data platform” conforms to the reference architecture.

DIN SPEC Open Urban Platform (OUP) The German standards organization DIN has picked up the activities of the Action Cluster Integrated Infrastructure and Processes on the MoU and developed an “Open Urban Platform” with a regional consortium consisting of members from cities, operators, vendors, and academia the DIN SPEC 91357[1]. The reference architecture of the MoU has served as a sound base as depicted in the figure below. Both core partners of WP3 in Cologne, the City of Cologne and [ui!], were members of the DIN SPEC team and provided strategic guidance. As consortium leader, [ui!] orchestrated input also from other members working in SCC01 projects such as Triangulum, Smarter Together and mySMARTLife.

Urban COCKPIT The GrowSmarter Cologne Urban COCKPIT is a solution developed on top of the open urban platform and is based on the [ui!] COCKPIT. It is designed to support analytics of real time data. By integrating, processing and visualizing data, a proof of concept can be done proving that the data is really available and in good quality. This is an important step for using and offering the data for value added services.

The WebAPP has been developed for GrowSmarter to provide insight in the different measures implemented in Cologne. It gives decision makers an easily understandable overview of the current and historical state of the pilot implementation. This includes traffic and parking loads, parking situations, energy consumption and production and mobility stations. All data is provided by the infrastructures and does not include personal data. It will be used to understand which data is available, at which quality in a human understandable way. It serves therefore also as a communication tool with other departments within the City administration as well as with external parties.

smarter.eu/fileadmin/editor-upload/Blogs/_10/Cologne/Urban_cockpit_view_1_and_2.png" height="300px" />

Urban cockpit main view and map view

The indicator on the left side of the Urban COCKPIT main page is pulsing and gives information of the current “pulse” of the city. In case of large traffic loads, much pollution, bad parking situations, high amount of non-regenerative energy consumption, etc. the pulse is very high which indicates the city suffers from “stress”. On the right side, different tiles or certain Smart City indicators are arranged. The timeline on the bottom of the cockpit can be used to see historical states of the city.

Federation of Open Urban PlatformsWithin the DIN SPEC 91357 and in alignment to the MoU, the federation of open urban platforms has been addressed. A federation allows different urban data platforms to exchange data in a transparent way thus that smart services in any given city can benefit from data sources even outside of the city as well as deploying smart services into other cities.

The below figure provides a schematic view of such a federation depicted from the DIN SPEC 91357.

smarter.eu/fileadmin/editor-upload/Blogs/_10/Cologne/Cologne_6_open_urban_platform_schematic_view.jpg" />

User scenario

Let’s assume, a start-up from Cologne would like to develop a mobile application that enables the multi-modal routing and integrated usage of public transport, electric mobility and different energy infrastructure elements (e.g. charging stations) across Germany. Therefore, the start-up obtains relevant data regarding the current city from the related Open Urban Platform via an Open Data Portal (e.g. https://offenedaten-koeln.de/). To extend their service to other cities in Germany the start-up uses the GovData.De portal and its data-catalog to lookup for Open Urban Platforms of other cities providing equivalent datasets and services required by their mobile application. The available information from the Open Data Portals and their corresponding Open Urban Platforms of Hamburg and Cologne has been harvested by integrating their data catalogs. This way the mobile application can transparently provide services both in Cologne and Hamburg, instead of having two APPs, e.g. one for each city. Given a user opens the mobile application in Cologne to plan a journey to Hamburg. The mobile application should provide the most convenient combination of transportation means concerning the traffic situation and public transport options and availability of charging stations.”

Our vision is therefore to connect the urban platforms within GrowSmarter across the three GrowSmarter lighthouse cities Stockholm, Cologne and Barcelona and if applicable between lighthouse cities and follower cities. This way, we allow for more smart services to be developed and thus creating an even larger ecosystem adhering to our ambitious goal of prosperity and growth.

Stockholm Blog #9: Looking at first evaluation results

In 2014, when we selected the smart solutions and the partners that would implement these in Stockholm, we wanted to show how a city can tackle the sustainability challenges of rapid urban growth. Now that these solutions are in place we want to evaluate the results to show that we can achieve the goals initially defined and do so in an economically sound way. When we look at the first set of evaluation data collected we can see at the same time promising results, no results at all and negative results. In many cases we simply do not have enough data to give an accurate answer. Also the systems have in many cases not been fully optimised and/or is running on partial capacity, so it is too early to define if they are working well.

Action area 1: Low-Energy Districts - What is happening in Valla Torg, Årsta and the Slakthus area buildings and what results do we have?

In Valla Torg the refurbishment of the two first multi-storey buildings (7G and 6) and the low-storey building 8 are finalised and the tenants have moved in. The evaluation of energy use has started, but the first set of evaluation data is not complete, so it is too early to tell how well the energy efficiency measures have worked. Refurbishment of the other buildings are still in progress and will be finalised between September 2018 and January 2019.

In the private condominia Brf Årstakrönet the evaluation is on its second year. The use of electricity, water and energy used for heating is evaluated. Each energy source is followed on a monthly basis and compared to the baseline.  Also the amount of solar energy produced by PV cells are measured.

Compared to 2015, the first full operational year of savings was around -10%, for district heating -30% for electricity (not including electricity used in apartments) and -4% for water.

In Slakthusarea the refurbishment of building 8 is finalised. The evaluation of energy use has started, but as the building and energy measures were so recently done there is no data yet available telling how well the energy efficiency measures have worked. The substitute buildings Kylhuset in Slakthusareaare also finalised for building related energy efficiency measures. The waste heat recovery will be installed in summer 2018 as well as the PVs combined with battery storage.

Action area 2: Integrated Infrastructures

Installing smart LED-lighting

The smart LED-street lights (solution 5) have now been in operation for 1,5 years and the system has worked well. There are three sub measures implemented and evaluated and the results for the first year of evaluation is presented below. It is important to understand that the baseline is LED-street lights. So the energy saving of replacing a metal halogen street 50 W with LED light of 30W is not included. This saving is about 30%.

  • The first sub measure is “Sensor controlled LED lighting for pedestrian and bicycle paths” to enable the lights to provide base lighting to satisfy the feeling of safety at all times and increase the level of lighting when someone approaches. The first 12 months of evaluation indicate an energy saving of 45,9% a year. The original target of 40-50% savings was thus reached.
  • The second sub measure is “Self-controlled LED street lighting with pre-set lighting schemes”. The first 12 months of evaluation indicate an energy saving of 14,4% a year. The original target of 20% savings was not reached in this first year.
  • The third sub measure is “Remote controlled LED street lighting which can be controlled from a distance”. The first 12 months of evaluation indicate an energy saving of 19,3% a year. The original target of 30-50% savings was not reached in this first year.

The next step will be to define how cost effective these sub measures have been.

A Smart Connected City

The aim of the measure 5.2 is to implement in the city environment, if possible on existing infrastructure, sensors for data collection, analysis, visualization and via an IOT platform also test the possibilities to use sensor data for direct communication to citizens as well as using flow data to pre-program and steer city infrastructure such as street lights.

Two types of sensors have been implemented in the Slakthusarea. The first type is 10 sensors for measuring vehicle traffic on a real-time base and the second type are wifi-based sensors to measure pedestrian and bicyclist traffic. The data from the sensors are analysed and visualised in the IOT platform provided by IBM. Below are some examples of visualised data analytics.

IBM, who is responsible for the open consolidated big data platform (solution 8), will build up a multiuseable data platform where real-time data can be analysed, but also were the data can be turned into practical usecases reducing transport emissions and increasing the quality of life for citizens. The development work is done in an agile process were users from different city organisations work together with IBMs development team. Currently the development team is working on developing a mobile application to help event visitors in the Slakthusarea to navigate in the area is a best possible way. In autumn the development team will start working with how the flow data collected could be used to steer street lights in the area.

Smart waste handling

The waste handling system provided by Envac has been running since the summer 2017. This solution (Measure 7.1, 7.2, and 7.3) demonstrates a smart waste solution for residential areas using differently coloured bags for different sorts of waste, transporting the bags long distance underground and sorting them automatically in a treatment plant. There are yet only two inlets in operation in the installation due to the general time plan of the refurbishment of the Valla torg site. When the AWCS is in full operation there will be 13 inlets, thus increasing the amount of waste significantly, in turn making the evaluation more relevant. The organic fraction can be used for biogas production, which in turn can be used in vehicles. So it is very promising that this fraction per quantity is the largest. 

Waste sorting results
Color Fraction Quantity Distribution
White Rest fraction 76 20,4%
Yellow Paper packaging 90 24,1%
Orange Plastic packaging 80 21,4%
Green Organic fraction 127 34,0%

Action area 3: Sustainable Urban Mobility

Building logistics centre and delivery boxes

The Building logistics centre (solution 2) implemented by Carrier, will start handling more materials for the last buildings to be refurbished in Valla Torg. Unfortunately the evaluation data is not yet available, so it is not possible to define how well the solution is working.

The implementation of delivery boxes (solution 9) by Carrier is done. The delivery boxes are actually a delivery room, which later on can be used for other purposes. The delivery room can be easily used for any type of deliveries, small and big. The deliveries are transported by bike to the room. When the package has arrived the tenant will get a message and with an app, open the door and then go and collect it.  The tenant can also put returning packages in a special shelf. As the system has been in use for a short time, only a tenfold of packages were delivered. The camera surveilled room together with identification of users and specified door codes guarantee that a package is not accessed by other users by mistake.

Smart Traffic Management

Insero has together with NOAE (Network of Automotive Excellence) implemented an information system for drivers (solution 10). Effects on travel time and the drivers’ experiences has not yet been evaluated.

KTH has developed a smart phone application to follow up changes in travel behaviour. In the same application, information about renewable fuels in Stockholm will be shown. The application is launched, but no evaluation data is available.  

Alternative fuel driven vehicles

As part of the GrowSmarter project, Fortum will install up to 10 charging stations and one fast charger (solution 11). The fast charger is installed in Årsta. The normal chargers are also installed in Valla Torg.

The first four refuelling stations for renewable fuels are up and running. The filling station in Årsta is expected to be built in 2018. Data from the first refuelling station shows some drastic results. The station was launched in 2016 as a renewable station and drivers did not think they could also get traditional diesel there. When they did understand this, the diesel sales increased. It is important to remember that only 10% of all trucks in Sweden are defined as green vehicles, so in that perspective 18% sales of biogas is a good result.

Stockholmshem launched its electrical carpool (solution 12) for tenants and habitants in February 2018. In February and March there were 14 tenants who have enrolled themselves to the carpool. The cars are frequently used especially during weekends.

Communication and marketing

An event for tenants in Valla Torg was organised 18th of April 2018. In the events Stockholm Site partners showed smart solutions for the tenants and they could also test solutions like the cargo bike. The event was successful and received positive feedback from tenants.

Cologne Blog #8: Exchanging with tenants and sharing Cologne's experiences

With construction nearly completed in Stegerwaldsiedlung, we held an informational event with tenants in the newly renovated buildings and area. We've also been actively participating in a number of international events, sharing the experiences of the GrowSmarter project in Cologne with interested parties from all around Europe and the world.

GrowSmarter dissemination

Informational event for the Stegerwaldsiedlung tenants

As the construction work in the project site area Stegerwaldsiedlung is almost complete, the project management and partners believed that it was time to hold an informational event for the neighbourhood tenants to inform about the process and foster acceptance. As the tenants stayed in their apartments during construction time, burdens such as long road closures, lack of parking spaces, construction noise, etc. had to be endured.

The City of Cologne together with the project partners invited the Stegerwaldsiedlung tenants to an informational event on November 7th, 2017. The invitations were distributed to all households in the project area and were available in all social insti-tutions.

The aim of the informational event was to inform the tenants about the measures and the current state of the implementation, and to report on the perspectives that arise for the entire district of Mülheim. The event was supported by an external moderator and facilitated by the Community Reporter group (a group was founded to teach professional video shooting and then accompany projects they choose in Co-logne). More than 100 tenants attended the event.

The project management welcomed the attendees, explained the project goals, pre-sented the status of the implementation and pointed out the perspective until the end of the project and beyond. Most importantly, the team explained the benefits of the project for the tenants. Two City of Cologne employees (City Strategic Planning and Urban Development) reported on how the district of Mülheim will develop in the areas of local supply, mobility and construction. The tenants were invited to ask questions and express their wishes. Many questions asked were related to the status of the construction site, new heating system, the parking situation and how high future rents will be.

As a result of this meeting, the City together with the partners will send a letter summarising the event’s results. DEWOG already sent a detailed letter explaining the new heating system and the energy cost saving potential. At the end of the event, the tenants had the opportunity to get to know each other personally. The Community Reporters produced a video showing the event and subsequent interviews with some of the participants. You can view the video here (in German):

The next tenant informational event is planned for May 2018.

Study visit at the World Climate Conference COP 23

The World Climate Change Conference took place in Bonn from November 6 to 17. For more information please visit the official website.

COP23 provided an extensive framework program surrounding the main programme for the conference participants. The aim of this programme was to show the participants as many projects as possible in the field of local climate protection activities. Within this context, the GrowSmarter project partners offered a study visit to the Stegerwaldsiedlung. The The study visit, which took place on 13 November, was announced in a press release as well as in the COP23 event programme, which all attendees received.

smarter.eu/fileadmin/editor-upload/Blogs/_9/Cologne/image4.jpg">Informational event for the tenants. Photo> Uta Konopka

The GrowSmarter team conducted the study visit at the Stegerwaldsiedlung in both German and English. 26 people participated in the study visit. The project management team explained the overarching GrowSmarter goals and the efforts in all three lighthouse cities. The local work-package leaders presented Cologne’s measures in energy, mobility and integrated infrastructure. During the neighbourhood tour, the participants were able to see the implementation of the measures first hand.

smarter.eu/fileadmin/editor-upload/Blogs/_9/Cologne/image5.jpeg">Study visit COP 23. Photo: Uta Konopka

The solutions related to energy retrofitting, energy management with the control of neighbourhood management and the mobility stations were of particular interest. Many questions came up, including which measures were particularly effective, the prospects for transferring the measures to other cities and how residents are in-volved. Participants were keen to continue the dialogue and to be kept informed about the project.

GrowSmarter at THERMOS conference in Brussels

This event took place at the Permanent Representation of Romania in Brussels on January 25th, 2018. It addressed the question of making integrated heating and cooling systems part of the backbone of Smart Cities and Communities, including concepts on local, open and affordable energy transition by providing state-of-the-art planning tools, solutions and insights.

Cologne was invited to speak on a panel, providing the city’s perspective on thermal optimisation and refurbishment in the framework of CELSIUS and GrowSmarter.

GrowSmarter at the SmartCity Replication Workshop in Brussels

The SCC replication workshop titled ”Learning from the successful” took place in Brussels on January 26th, 2018 and focused on the question of how Lighthouse city Smart Solutions can be replicated in Follower Cities. How can stumbling blocks be overcome in order to achieve replication possibilities of Horizon 2020 projects and their solutions for Follower Cities? Three workshops, each held twice, were divided into 4-5 roundtables for the topics of energy, integrated infrastructure and mobility. The event saw more than 100 participants in the moderated workshops. Cologne moderated the mobility roundtable, and car-sharer provider Cambio gave information on setting up mobility stations, as has been done in Cologne. Cologne’s energy provider, RheinEnergie, participated in the roundtable on virtual power plants/energy management systems, including storage. Each roundtable discussion was facilitated by a moderator who introduced presenters from industrial and city partners. The sessions started with a presentation touching on the planning, implementation, technical evaluation, business model and the replication possibilities of specific solutions. The participants then had 40 minutes to discuss barriers and possibilities to replicate.

At the end of the workshops, the moderators summarised the key success factors and how to overcome the main obstacles.

The first construction phase has been completed and the evaluation began in January 2018, as planned. The remaining construction phases are scheduled to be completed by March 2018, after which their evaluation phase will also begin.

Both RheinEnergie AG and AGT international will send informational letters to all Stegerwaldsiedlung tenants until March and inform them about the possibility to have the Smart Home system installed for free. This will be done in up to 50 homes. If there are more interested tenants than expected, RheinEnergie will have to assign them by lot.

RheinEnergie AG was able to find a manufacturer who was prepared to equip its smart home system with an interface that enables AGT to collect and measure the required data (WP3). The system will be presented and demonstrated to the tenants in a workshop, where they can learn how to operate it in person and understand the advantages of the system. We intend to cover the first experiences with the system our the next blog update.

The community driven project ”OpenAir Cologne” has made progress; in the past months, the website has been editorially revised and the project was presented at several different events.

OpenAir Cologne is a joint project of the Oklab Cologne, the City of Cologne, the TH (University of applied Sciences), the University of Cologne and the For-schungszentrum Jülich (research center). The project focuses on generating data, especially measurements of fine particulate matter, through environmental sensors. This project is the outcome of an idea from citizens, supported by science based institutions and initiated by the City of Cologne.

smarter.eu/fileadmin/editor-upload/Blogs/_9/Cologne/image10.png">Data fine dust collected from environmental sensors. Photo: City of Cologne

The overall idea came about via “Citizen Science”, in which citizens and their ideas and perspectives are actively involved in governmental tasks. The objective is to connect citizens with their local public administration and to accelerate cooperation between the government and the inhabitants in the areas of Open Data, participation and citizen information. The greater purpose in this context is to enable an actual collaboration between citizens and the government.

The project is being implemented by collecting sensor data from volunteers and processing them for the community as Open Data, as well as to open them for discussion and to review their informational value. The goal is that the sensors will allow coverage of a large area in order to generate as much reliable information as possible. To support the project, the city offers different types of workshops, from soldering to understanding weather forecasts.

Given the current situation, OpenAir Cologne was able to set up 50 environmental sensors in the urban area of Cologne. Most importantly, it was possible to raise awareness and interest for the environment and to disseminate environmental topics amongst the public.

All ten planned mobility stations are now in place, in various sizes and with various combinations of partners. Three mobility stations will be equipped with e-bikes this month and next. Photos of the individual stations can also be found in our previous blog post.

smarter.eu/fileadmin/editor-upload/Blogs/_9/Cologne/image12.jpg"> Overview of Mobility Stations and partners involved

After overcoming some legal stumbling blocks for ampido locations in public spaces, the team has now been able to integrate this partner with the inclusion of some spe-cial clauses in the law. Ampido is equipping the Mobility Stations with parking spac-es that can be booked in advance. This system has so far only worked on private land and is now possible on public lands for the duration of the project or until city ordinances change. Ampido is represented at the Mobility Stations found in the map above. Some of the stations have already been shown in previous blogs. These photos show only ampido’s spaces, as they are the most recent additions.

The mobility card: “MultiTicket”

The mobility partners in the project are convinced that better utilisation of Mobility Stations depends on their attractiveness. cambio CarSharing and KVB have there-fore developed a combined mobility card: the “MultiTicket”. With the MultiTicket all means of transport (bus, tram, car- and bike-sharing) can be used. It is a further de-velopment of the existing "JobTicket", a monthly ticket paid for by companies for their employees. All JobTicket users are now able to register with cambio in order to use their car-sharing cars. The cars themselves can be opened with the MultiTicket - no further card is needed. In addition to public transport, all MultiTicket users get a dis-count of 10% for car-sharing.

The MultiTicket, which became available in October 2017, offers virtual consolidation by bringing the various modes of transport to one place, which the Mobility Sta-tion does physically.

smarter.eu/fileadmin/editor-upload/Blogs/_9/Cologne/image17.jpg">Multiticket

The introduction of the MultiTicket has not yet been promoted with a major press and advertising campaign. Still, the offer was very well received - almost 500 people have registered already, almost one third of the overall new cambio customers since October 2017. The use of the new Mobility Stations in the Mülheim project area has also increased. In the near future, further advertisement of the MultiTicket is planned in order to gain more customers and to make the Mobility Stations even more successful.

An example of the cambio CarSharing flyer advertisement can be seen below:

Stockholm Blog #8: Inside a flow

Csíkszentmihályi, who defined the state of flow, has said, "If challenges are too low, one gets back to flow by increasing them. If challenges are too great, one can return to the flow state by learning new skills.". Even if it is often referred to a personal state of mind, it could also be put in the context of the smart solutions implemented as a joint effort in Stockholm. Most of the solutions in Stockholm are implemented the first time in a larger scope, with high goals and a very tough schedule, but they are also very tightly linked to each other. Now that the implementation phase for most parts is over or in a repetitive phase it becomes evident how challenging the project actually has been and how it has required developing new skills. Now we are stepping out of this state of flow and starting sharing our experiences. And I think we have a very interesting story to tell.

Action area 1: Low-Energy Districts

What is happening in Valla Torg, Årsta and the Slakthus area buildings?

To see all the measures to be implemented, click here

In Valla Torg the refurbishment of the two first multi-storey buildings (7G and 6) are finalised and the tenants have moved in. The evaluation of energy use has started and will continue until the end of the project to secure a 2-year evaluation time.

The second half of the low-storey building 8 is finalised and tenants have moved in.

In the private condominia Brf Årstakrönet the evaluation is on its second year indicating clear energy savings.

In Slakthusarea the refurbishment of building 8 is finalised. The new tenant, nightclub Slaktkyrkan, is open and have a full schedule of live shows planned for this spring. The pictures below show some of the energy efficiency measures implemented.

Installing smart LED-lighting

The smart LED-street lights (solution 5) have now been in operation for 1,5 years and the system has worked well. The results have been so promising that now the City of Stockholm will scale up this solution on a district level.

A Smart Connected City

In Stockholm the smart connected city will use the extensive fibre network provided and administered by Stokab, a company owned by Stockholm City Council (more information) Several Internet of Things applications and solutions can be developed thanks to the fibre network.

The implementation of sensors in the Slakthusarea is soon finalised. Most of the sensors for vehicle traffic flow measurements are now installed and most of the wifi-based sensors are going to be installed within the next two weeks.

IBM, who is responsible for the open consolidated big data platform (solution 8), will build up a multiuseable data platform where real-time data can be analysed, but also were the data can be turned into practical usecases reducing transport emissions and increasing the quality of life for citizens. The development work will be done in an agile process were users from different city organisations work together with IBM:s development team.

Waste Heat recovery

Fortum’s open district heating (solution 6) system has been operating during the heating season and has given better results than expected. The heat recovery can thus heat up more than the earlier calculated 700 apartments.

Smart waste handling

The waste handling system provided by Envac has been running since summer. The system has worked well with the bags provided for this purpose, but in some cases the tenants have used other plastic bags which has unfortunately broken. In the picture below you can see how the waste fractions look like inside the container before the delivery to the end sorting facility.

Building logistics centre and delivery boxes

The Building logistics centre (solution 2) implemented by Carrier, will start handling more materials for the last buildings to be refurbished in Valla Torg. Carrier has together with Skanska agreed which material streams can be best handled by the logistics centre, and these materials will be handled by the centre during 2018.

The implementation of delivery boxes (solution 9) by Carrier is done. The delivery boxes are actually a delivery room, which later on can be used for other purposes. In the room for instance tools could be safely kept and booked by tenants.

Smart Traffic Management

Insero has together with NOAE (Network of Automotive Excellence) implemented an information system for drivers (solution 10). Effects on travel time and the drivers’ experiences will be evaluated.

KTH has developed a smart phone application (solution 10) to follow up changes in travel behaviour. In the same application, information about renewable fuels in Stockholm will be shown. The application is launched.

Alternative fuel driven vehicles

As part of the GrowSmarter project, Fortum will install up to 10 charging stations and one fast charger (solution 11). The fast charger is installed in Årsta. The normal chargers are also installed in Valla Torg.

The first four refuelling stations (solution 11) for renewable fuels are up and running. The filling station in Årsta is expected to be built in 2018.

Stockholmshem launched yesterday its electrical carpool (solution 12) for tenants and habitants.

Communication and marketing

In Stockholm Emma Borggren-Franck has taken the responsibility of the demonstration of smart solutions. Several study visits have been organised and still more are planned for this year. There has also been a great interest for presentations of the smart solutions implemented in Stockholm. A few weeks ago we presented our experiences in Brussels and last week I was in Wien and Bratislava presenting results and experiences. In spring there are two events planned. One will be focused on the smart solutions in Slakthusarea and the second one on smart solutions for tenants in Valla Torg.

Barcelona blog #7: Urban-scale air quality monitoring and microdistribution

Read about how Barcelona will pilot a beyond state-of-the-art wind and air quality monitoring network, including how it will integrate with the GrowSmarter platform. In addition, the first results from our last-mile delivery services with electric bicycles are available!




Action area 2: Integrated Infrastructures
To see all the measures to be implemented, click here.

Sensor deployment in the 22@ district of Barcelona
Within GrowSmarter, measures are being carried out to develop an air quality model at the urban-scale using Computational Fluid Dynamics (CFD) simulations. In order to provide real-case inputs for the operational air quality nowcasting and the short-term forecasting of the CFD models, a set of monitoring sensors will be deployed in an initial pilot area in Barcelona. The monitoring nodes, composed of wind and air quality sensors, will be installed in 4 Smart Towers in the 22@ district. This use case will also include vehicle counting equipment for emission monitoring purposes.

An urban-scale air quality model - why?
Air quality and associated impacts on public health are matters of growing concern in many urban areas. Public administration and health agencies are tasked to monitor the quality of air and, eventually, to make model forecasts to assist the adoption of reactive measures and to warn the public of air pollution that could affect vulnerable groups of citizens.

Urban-scale pollutant dispersion models require of two critical inputs: high-resolution wind fields near urban-scale morphologies (buildings) and pollutant sources (mainly derived from vehicle combustion) through sensors and emission inventories. Today, the increase in computational capabilities is making it possible to envisage a near-future scenario in which Computational Fluid Dynamics (CFD) models will be used to simulate urban-scale winds and pollutant dispersion operationally. In this scenario, the massive deployment of low-cost sensors for monitoring wind and the concentration of critical pollutants will be critical.

Web-based graphical user interface for visualisation of air quality results


Sensor deployment at 22@ district of Barcelona
Using the city of Barcelona as a test bed, this use case will deploy a low-cost sensor network to extend the current monitoring network of environmental sensors to selected urban areas of Barcelona. Real-time data will be used to initialise and validate an in-house CFD-based high-resolution (tens of meters, hourly output) urban-scale air quality model before its operational implementation. This system is being developed at the Barcelona Supercomputing Center (BSC) in a joint collaboration with the Barcelona City Council (IMI - Municipal Institute of Information) and the CAPTOR project, who provides the monitoring nodes that integrate the air quality and wind sensors.

The monitoring nodes for wind and air quality will be installed in 4 GrowSmarter Smart Towers in the 22@ district, also including vehicle counting equipment for emission monitoring purposes.

The use case will deploy a monitoring system for:

  • Wind field (speed and direction),
  • Air quality (NO2 and O3),
  • Flow of vehicles (vehicles per minute).


  • Each monitoring node will be composed of an Arduino node, which have been developed as part of the Horizon 2020 CAPTOR project, and integrating several sensors on a single device. This control hardware node is in charge of monitoring, management and post-processing of raw data coming from the following integrated sensors:

    • a Davis anemometer for wind direction and velocity
    • several (up to 3) NO2 MOX sensors
    • several (up to 3) O3 MOX sensors
    • vehicle sensor to detect flow of vehicles


    The environmental Arduino nodes will be deployed in the 22@ district and are self-contained packs that are designed to be installed on public street lights and poles at a minimum height of 5 meters to avoid vandalism. All the devices in this pack are designed to be long-lasting and highly durable to reduce maintenance. This installation pack is composed of the components shown in below:

    smarter.eu/fileadmin/editor-upload/Blogs/_8/Barcelona/table.png">
    Components of the Arduino pack


    The collected data will be sent to the GrowSmarter platform through the GrowSmarter API. The data will be used by the air quality monitoring software (nowcasting) developed by BSC-CNS that can predict wind fields in the streets with a resolution of 10 metres and 1 hour, and gas concentration with resolution of 10 metres and 1 hour. These resolution values are beyond the state of the art in air quality modelling for nowcasting.

    Moreover, the sensing data information and the sensor-derived nowcasting maps will be offered as Open Data to third parties through the GrowSmarter platform so that consumers of these environmental data can use this information to provide environmental monitoring services.

    Benefits for GrowSmarter
    This use case is a clear example of synergies gained from integrating infrastructures of GrowSmarter: The Smart Towers will provide support for the monitoring nodes and provide communication infrastructure, while the GrowSmarter platform will provide the required data storage for the collected data. The air monitoring software is an example of a service developed on top of the GrowSmarter platform that will provide monitoring services. Moreover, this use case is an example of collaboration among different entities and projects beyond the GrowSmarter project.

    First results on the microdistribution of freight in Barcelona
    In January 2017 the microdistribution platform became operational. The service is offered by the company Vanapedal. The municipality of Barcelona has leased a public space to the company, which is obliged to be neutral in the market and work with any logistics operator willing to use the service.

    The main objectives of the measure are to:

    • Introduce a more efficient and effective freight transport system in the city centre,
    • Analyse the administrative management of a public concession,
      Analyse the business model of the service,
    • Analyse the reduction in CO2 and vehicle kilometres due to shift from conventional vehicles to electric bikes, and
    • Test a new sensor system to measure pollutants and other environmental parameters using the bicycles of the service.


    The Last Mile Operator Vanapedal offers different services, the most relevant of which is the distribution of parcels and packages from other carriers to their final destination. Carriers bring these items to the microplatform which is conveniently located close to the city centre. These are then transferred to electric bicycles and tricycles. The last mile is then performed by drivers from Vanapedal following their established routes. Parking and access regulation do not apply to bicycles, so no delivery time window restrictions affect the distribution.

    The service has been running since January 2017 from the Estació de França location with success, although the market is difficult to reach since there are also competitors and some logistics companies have begun operating their own last mile deliveries using sustainable modes of transport.

    smarter.eu/fileadmin/editor-upload/Blogs/_8/Barcelona/image7.jpg">
    Location of the microplatform at Estació de França


    Currently, up to 9 bicycles are being used in daily operation. The company gathers all business information of their operations including the daily number of deliveries and pick-ups, the number of kilometres covered and the time needed to cover all routes. This information is being collected monthly and the first results of the analysis of this information have been made. During the first three months of operations, 23,000 journeys have been performed and an increase in the daily number has been noted.

    smarter.eu/fileadmin/editor-upload/Blogs/_8/Barcelona/image8.png">
    Average daily number of journeys


    In February, the average distance covered was of 65.5km/day, while in March this figure increased to 160km/day due to the introduction of three more tricycles.

    smarter.eu/fileadmin/editor-upload/Blogs/_8/Barcelona/image9.png">
    Km performed by all bikes daily between January and March 2017


    Also, the effectiveness of the deliveries is being monitored. So far, the average percentage of successful deliveries has been 92.73%. This value has increased over time, but it is seen as very good compared to conventional carriers.

    smarter.eu/fileadmin/editor-upload/Blogs/_8/Barcelona/image10.png">
    Evolution of the daily effectiveness of deliveries


    The next step is to continue analysing the data obtained from the operator of the microplatform and compare it with the data obtained from the sensors that have been installed in three bicycles that offer further information such as the routes followed or the concentration of contaminants.

    The last step of the process will determine how much traffic and CO2 this measure has reduced. This will help to encourage other cities to implement similar last mile services.

Stockholm blog #7: Tenants are moving in...

The personnel from Skanska and Stockholmshem have been working hard to finalise the buildings so that the tenants can start moving back as planned in September. In the last weeks, construction workers have been working nights and weekends to accomplish this. Now the first tenants have moved in and can start using all the smart solutions we have implemented. As soon as the heating season starts (we all wish the first snow would just come!) we can start getting some indications on how energy efficient the buildings are.


Action area 1: Low-Energy Districts

Installing smart LED-lighting


The smart LED-street lights (solution 5) have now been in operation for a year.


A Smart Connected City


In Stockholm the smart connected city will use the extensive fibre network provided and administered by Stokab, a company owned by Stockholm City Council (more information). Several Internet of Things applications and solutions can be built on top of the fibre network.


The implementation of sensors in the Slakthusarea has started. IBM, who is responsible for the open consolidated big data platform (solution 8), will analyse data to show how people move around in the Slakthusarea. This starts as soon as the sensors can provide data in October. The project team, platform for data management, analysis tools and methodology are all in place.


Waste heat recovery


Fortum’s open district heating (solution 6) system is now installed in the datacentre. The heat recover can heat up approximately 700 apartments.

Building logistics centre and delivery boxes


The Building logistics centre (solution 2), implemented by Carrier, will start handling more materials in autumn. Carrier has together with Skanska agreed which material streams can be best handled by the logistics centre, and these materials will be handled by the centre when the next phase of the refurbishment begins later in the autumn.


 


The implementation of delivery boxes (solution 9) by Carrier is being done alongside refurbishments of buildings in Valla Torg. When the tenants move back into their apartments starting in September, they can order packages and other deliveries straight to their homes instead of retrieving them from the nearest service point. The delivery from the service point to the building is carried out with cargo bikes.


Smart Traffic Management


KTH has developed a smart phone application (solution 10) to follow up changes in travel behaviour in a way that is more effective and has a greater response rate than traditional travel surveys. This will improve travel demand management measures. In the same application, information about renewable fuels in Stockholm will be shown. This information includes updated information on where each alternative fuel can be tanked, together with the most recent prices. The application will be launched when tenants have moved back later this autumn.


Alternative fuel driven vehicles


As part of the GrowSmarter project, Fortum will install up to 10 charging stations and one fast charger (solution 11). The fast charger is installed in Årsta. The normal chargers are also installed in Valla Torg.


The first three refuelling station (solution 11) for renewable fuels are up and running. The filling station in Årsta is expected to be built in the beginning of 2018.


Communication and marketing


In Stockholm several study visits have been arranged and there is high interest in the GrowSmarter solutions. As more and more smart solutions are implemented, the study visits will become more frequent. In October 2017 there will be an event demonstrating the smart solutions in Valla Torg. Here the focus is on city representatives. In November/December 2017 a similar event will be arranged in Slakthusarea. In spring 2018 an event is planned for tenants in Valla Torg.


A video has been produced showcasing the smart solutions implemented in Stockholm. The video can be seen here.

Cologne blog #7: The Day of Good Life

With the first phase of construction completed in the Stegerwaldsiedlung, all that remains to do is to connect the Siedlungsmanagement software. In the world of data, we are also working with a broad range of Cologne's open data to integrate into the urban cockpit. Lastly, our mobility stations - featuring carsharing and electric vehicle charging - are operational. Read on for more details and pictures!



GrowSmarter on the “Tag des guten Lebens/ Day of Good Life”

The “Day of Good Life” is a family and neighbourhood festival for the entire district of Deutz, just south of our project area Mülheim. To show how a district can evolve, thirty streets in Deutz and the Deutzer Bridge across the river Rhine were closed to traffic. On Sunday, 18 June approximately 150,000 visitors came to the Day of Good Life event, a visitor record. All activities had the aim of testing a joint venture on how life in Deutz could be made sustainable and future-oriented over the coming decades. At the GrowSmarter booth, visitors were particularly interested in alternative mobility solutions. The industry partner Cambio CarSharing offered free registration, an attractive that offer was taken advantage of by 37 people.

Universities

Students and instructors from three foreign universities would soon like to visit Cologne for a knowledge exchange. The representatives from the University of Barcelona know the GrowSmarter activities in their own city and would like to see how Cologne is implementing their measures. Students at the University of Basel are very interested in learning more about the development of open data platforms.


Exchange of experts with a delegation from China
Study Visit on July 6, 2017

The German state of North Rhine-Westphalia (NRW) and the Republic of China have reached an agreement on environmental cooperation. China is interested in implementing the objectives of the Paris Climate Protection Agreement. The representatives of the provinces and municipalities are important players in this process of change. The “Deutsche Gesellschaft für Internationale Zusammenarbeit” (GIZ) (Association for International Cooperation) organises regular exchange programs with the support of the German Ministry of the Environment. The aim of the program is the acquisition of new knowledge and the exchange with experts, as well as the deepening of old contacts and the establishment of new contacts for the purpose of the cooperation between North Rhine-Westfalia and China. The focus of the trade exchange and the partner province representatives from Sichuan, Shanxi and Jiangsu was “Emission Control, Air Pollution and Renewable Energies". The representatives were keen on understanding more about GrowSmarter energy measures with the aim to examine which of the measures could be implemented and replicated in China. The delegation was made up of company officials and municipal representatives as well as the regional NRW government guests.

Welcome and presentation in the Stegerwald settlement office


The project was presented to the visitors in the Stegerwald neighbourhood office. The project`s integrated approach was new to the visitors. This aspect was of paramount importance to representatives of municipalities in order to achieve sustainable city planning. RheinEnergie presented its energy management measures.

Presentation of Demonstration Buildings before and after refurbishment


During the tour of the settlement, the participants visited the facilities and were able to ask technical questions.


Particularly interesting for the engineers was the new “Siedlungsmanagement” software (virtual power plant). The approach of saving as much energy as possible in a building as well as implementing intelligent control for a larger number of buildings will be examined by some representatives for their projects in China. There was mutual interest in pursuing this knowledge exchange in the future.


SmartCity conference in Esch-sur-Alzette

In mid-September, Cologne had the chance to present GrowSmarter at the SmartCity conference in its twin city, Esch-sur-Alzette, Luxemburg. Esch-sur-Alzette is planning to develop models for the cross-border region with Belgium and France.

The Cologne process of choosing the data platform and urban cockpit was of particular interest for Esch-sur-Alzette. The city is planning to implement a uniform digitalisation strategy for the entire region. Everyone was convinced that a smart city can only be realised with an integrated approach.

We have made great progress in this area convincing partners that sharing their data for GrowSmarter will be beneficial for all.


In August of 2016 we reported about the Cologne open data platform (www.offenedaten-koeln.de). This was in place before GrowSmarter, but it offers a comprehensive database, which can be used for the project.


Some very interesting records of the KVB could be included in the open data platform (www.offenedaten-koeln.de/dataset/og_group_ref/37972). It becomes evident that data from our partner KVB is not only a benefit for GrowSmarter but the entire open data community.


For example, errors or failures in the escalators and lifts at the railway stations can be called up in real time. With these data, it is possible to individually define an accessible, personalised route before starting a journey. The data can also be used to ensure that the departure from a platform is possible without complications during the journey. The use of railway is therefore more attractive for people with limited mobility or mothers with baby carriages, for example. We have thus taken another step towards stimulating the population in rethinking their choice of transport.


For the individual data sets we distinguish between dynamic and static data; this is dynamic data:

Our partner [ui!] - the urban institute is now working on integrating multiple data streams into the urban cockpit.

Action area 3: Sustainable Urban Mobility

To see all the measures to be implemented, click here.


Almost all mobility stations are now fully operational. The mobility stations are easily accessible by foot, bus and/or train. The first experiences show that the stations are accepted among transport users.


With the exception of one station, the RheinEnergie charging stations are implemented. All charging stations have two charging points. All stations also include a Cambio CarSharing station. The industrial partner KVB was able to find a suitable partner for the E-bikes procurement, and by the end of the year 10 e-bikes are planned to be implemented. They will be installed at the sites Charles de Gaulle Platz, Mülheim train station and the Stegerwaldsiedlung. Ampido is represented at two of the three main mobility stations so far.

The current situation at each of the stations is presented below:


Charles-de-Gaulle Platz

The Charles-de-Gaulle Platz provides 5 spaces for CarSharing cars (3 conventional cars, 2 e-cars), 12 bikes (7 conventional, 5 e-bikes), 4 Ampido parking spaces and 4 charging stations. This location also provides a public charging station with two charging points for the general public.

In 2015, the conversation between the City of Cologne and the state legislation regarding unified coordinated signage for the mobility stations thorughout the state started to take shape. This development is unique and has influenced the region’s cities and communities in using the same language of signage in their development of mobility stations.

The industrial partners KVB and Cambio are expecting a much greater use of the mobility stations after the introduction of the mobility card.


Users of public transport must have the possibility to use bus, tram (lightrail), bicycles and passenger cars with one ticket. Cambio and KVB are currently developing a so called “Mobiltätskarte (Mobilticket)”, an enhancement of the already existing subscription ticket. With this “Mobiltätskarte” travellers will be able to use bus, trams, bicycles and carsharing cars with their normal ticket.

Stockholm blog #6: Adaptive control for smart cities

The winter and spring weather in Sweden has been very odd, with the weather changing from cold to warm from one day to another. This year we had minus degrees and snow during Easter in late April. With the adaptive systems we have installed we have still been able to keep a steady indoor temperature inside the apartments. With traditional systems it would have either been too cold or too warm. We have also received good results from the smart street lighting and the combined renewable energy production, control and storage system. All these solutions are examples of adaptive control in cities. In this blog I will write some more about these and the other adaptive control systems we are now implementing.


Action area 1: Low-Energy Districts


What is happening in Valla Torg, Årsta and the Slakthus area buildings?


To see all the measures to be implemented, click here


The smart solutions for low energy districts will be rolled out in the building zones in Valla Torg, Årsta and the Slakthus areas (see map here). For an overview of the measures being implemented, click here.


smarter.eu/fileadmin/editor-upload/Blogs/_7/Stockholm/valla_torg.jpg" />

In Valla Torg the refurbishment of the first multi-storey building (7G) is going forward and many of the smart energy saving solutions are already implemented. All installations will be finalised in the summer and tested in August. The tenants start moving back into their apartments in September. When the next heating season starts, we can begin evaluating exactly how much energy we can save in these buildings. In this building the tenants have the possibility to use the Active House application from Fortum to control the temperature and lighting in the apartment. They can also use the home/away button, which means that when they leave the apartment to go to work or on holiday, they can cut unnecessary electricity and lower the temperature a few degrees in the apartment. With a mobile application they can push the home button, which will adjust heating and electricity back to normal before they arrive home.


In the private condominiums Brf Årstakrönet the adaptive control system by Veolia has been in operation for more than a year and has resulted in substantial energy savings as well as more stable temperatures in the apartments over the year. The energy hub that consists of photovoltaics, a current equalizer and battery storage has been in use for half a year. The system provides a higher output of solar electricity and a better interface between the production and use of locally produced electricity.


In Slakthusarea the refurbishment of building 8 is well on its way and will be finalised in autumn 2017 by the Fastighetskontoret (Real estate administration office). The selection for a substitute building in Slakthusarea is done and is only waiting for an official approval from the Commission. Work on the substitute building can begin in summer 2017 and all energy saving solutions are to be implemented during this year.

Installing smart LED-lighting


The smart LED-street lights (solution 5) have now been in operation for a year. There are three different methods used to adjust the street lights to use less energy while still providing the same sense of security for pedestrians and bicyclists. The first method is applied to street lights on a walking/bicycling path. When there is no movement the lights reduce to 40% capacity. When a person approaches, the lights ramp up to full power and when the person has passed they dim down again. The second method is that each individual luminaire keeps track of when it is turned on and off and uses those times to calculate a middle point. From that middle point, the brightness is lowered to 66% for a duration of 6 hours, or until it is turned off. In the third method, all luminaires are connected to a Central Management System where a dimming schedule runs. In the dimming schedule, lighting levels are set according to sunset/sunrise and specific times during the night. The lighting is turned on at sunset to 100%, at 10 PM it is dimmed to 67%, at 1 AM it is dimmed to 50%, at 5 AM it dims up to 67% again, at 6 AM 100% and is turned off again at sunrise.


A Smart Connected City


In Stockholm the smart connected city will use the extensive fibre network provided and administered by Stokab, a company owned by Stockholm City Council (more information) Several Internet of Things applications and solutions can be built on top of the fibre network.


The implementation of sensors in the Slakthusarea has faced data protection issues which needed to be examined very carefully. Even if both solutions have previously been used at small scales in other cities, they have never been combined. The combination of sensors measuring the pedestrian, bicycle and vehicle traffic in the area will provide very accurate information about the movement of people. A communication plan must also be produced to communicate to citizens that sensors are collecting data from passing vehicles and mobile phones to be able to provide better traffic flow in the areas, especially during events. The implementation of sensors will be done during August so that the communication plan can be finalised before implementation.


IBM, who is responsible for the open consolidated big data platform (solution 8), will analyse data to show how people move around in the Slakthusarea. This starts as soon as the sensors can provide data. The project team, platform for data management, analysis tools and method are all in place.


Waste Heat recovery


Fortum’s open district heating (solution 6) system has been recovering heat from a Supermarket in Farsta, some 5km south of the Slakthus area. The installations in the data centre will be done in June and as soon as the heating season starts again, the waste heat can be used to heat buildings.


Smart waste handling


The waste handling system provided by Envac will be completed by the end of June. The underground parts of the smart waste handling system (solution 7) are in place (see image below). The terminal and inlets are now being installed.

Building logistics centre and delivery boxes


The Building logistics centre (solution 2) implemented by Carrier, will start handling more materials in autumn. Carrier has together with Skanska agreed which material streams can be best handled by the logistics centre, and these materials will be handled by the centre when the next phase of the refurbishment begins later in the autumn.


The implementation of delivery boxes (solution 9) by Carrier is being done alongside refurbishments of buildings in Valla Torg. When the tenants move back into their apartments starting in September, they can order packages and other deliveries straight to their homes instead of retrieving them from the nearest service point. The delivery from the service point to the building is done by cargo bikes.


Smart Traffic Management


Insero is together with NOAE (Network of Automotive Excellence) and Global car OEM, implementing an information system for drivers (solution 10). In Stockholm, ten traffic lights are equipped with software that can communicate and provide information about the status of the light and when it is about to switch to another colour. This is achieved through a data connection between the traffic light, the cars’ on board software and GPS, and a central computer handling the calculations. Through a special device in the car, the driver can receive information on what speed to adopt in order to reach a green light at the next intersection. This information tool will be tested in two cars starting in May/June 2017. Effects on travel time and the drivers’ experiences will be evaluated.


KTH has developed a smart phone application (solution 10) to follow up changes in travel behaviour in a way that is more effective and has a greater response rate than traditional travel surveys. This will improve travel demand management measures. In the same application, information about renewable fuels in Stockholm will be shown. This information includes updated information on where each alternative fuel can be tanked, together with the most recent prices.


Alternative fuel driven vehicles


As part of the GrowSmarter project, Fortum has planned to install up to 10 charging stations and one fast charger (solution 11). The fast charger is installed in Årsta. The normal chargers will be installed in Valla Torg, Slakthus area and Årsta by the end of 2017.


The first refuelling station (solution 11) for renewable fuels is up and running. The filling station in Årsta is expected to be built in the beginning of 2018.


Communication and marketing


In Stockholm several study visits have been arranged and there is high interest in the GrowSmarter solutions. As more and more smart solutions are implemented, the study visits will become more frequent. In August 2017 there is a plan to have an event demonstrating the smart solutions in Valla Torg. Here the focus is on city representatives. In November/December 2017 a similar event will be arranged in Slakthusarea. In spring 2018 an event is planned for tenants in Valla Torg.


A video has been produced showcasing the smart solutions implemented in Stockholm. The video will soon be available at the GrowSmarter website.
