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. 

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.

All photos from the tenant event was taken by Bengt Alm.

In Slakthusarea an inauguration was held 15th of May introducing the smart solutions implemented in the area. Some 100 persons from different organisations attended the event. It was a wonderful weather and the visitors had a possibility to both listen to presentations as well as see the solutions in practice in a study visit.

All photos from the Slakthusarea event was taken by Sven Lindwall.

With this I want to wish you a very nice summer.

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.

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.

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.

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

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.

In Valla Torg the refurbishment of the first multi-storey building (7G) is on the finish line. There is still some minor painting work to be done in apartments, but all energy efficiency solutions are implemented. Here are some photos of the building:

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.

Installations in the datacentre

Smart waste handling

The waste handling system provided by Envac was completed by the end of June. The pipelines, inlets and terminal of the smart waste handling system (solution 7) are in place. The terminal and inlets are now being installed.

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.

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.

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.

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.

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.

GrowSmarter has reached a milestone year: by the end of 2017, all the smart solutions will be in place and in use in Stockholm. Smart solutions from each area of action have already been implemented, so the work is now shifting from implementation to demonstration and evaluation of the project. A lot of emphasis is put on communication and marketing activities in 2017 and 2018. Each partner will make a communication plan and contribute to the demonstration site’s general communication activity plan, but also look into how the smart solutions can be marketed internationally.

Action area 1: Low-Energy Districts

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

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

In Valla Torg The refurbishment of the first higher storey building (7G) started in September 2016. Insulation of facades, installation of new windows and other climate shell related measures were carried out by Skanska.

The refurbishment of the first lower storey building (8H) started in October 2016. Work on insulating facades and changing windows has already been done, and other climate shell measures will be finalised by the end of March 2017.

The refurbishment of the second higher storey building (6F) started in December 2016. All of the measures to be implemented are part of the energy efficient climate shell (solution 1).

In the private condominia, Brf Årstakrönet, the implementation (solution 1) and (solution 3) started in January 2016 with the installation of an adaptive control system by Veolia. Veolia has also installed photovoltaic arrays (solution 4) on the roofs. The solar energy production is connected with energy storage (batteries), so that solar energy can be stored and used when it’s needed. The same solutions will also be implemented in the Slakthus area buildings during later stages of refurbishment.

In Slakthus the refurbishment of building 8 by the Fastighetskontoret (Real Estate Administration Office) started in October 2016. Unfortunately, the overall budget for the Real Estate Administration was cut, so the second building (building 7) cannot be refurbished in 2017 as planned. Therefore, we are working on finding a replacement building. The alternative building will also be situated in Slakthus area.

Installing smart LED-lighting

As described in an earlier blog, the installation of smart LED-street lights (solution 5) was finalised in June 2016 in Valla Torg and has now been in use for a full winter season. The measure will bring an estimated 50% energy savings, but actual figures have not yet been analysed.

A Smart Connected City

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

In April 2017 sensors will be installed in the Slakthus area. One set of sensors will measure the pedestrian and bicycle traffic in the area. Another set of sensors will analyse vehicle traffic. We are especially interested in understanding how people travel to events that take place in this area: there are three sports arenas situated close to each other which host events year-round.

We will also install sensors for measuring air pollution. These will be placed in the same locations as the vehicle transport sensors. The real-time data that is collected will be delivered to an open consolidated big data platform for further analysis. A workshop with city departments and other interested parties is planned for the 8th of March to define the types of analysis to be done. Later in spring when the first set of data has been analysed, further workshops will be planned to define what kind of applications can be developed for lowering transport-based emissions based on the real-time data. In doing this we are defining ways to provide higher quality of life for citizens with smart connected solutions.

IBM, who are responsible for the open consolidated big data platform (solution 8), have two ongoing roles in GrowSmarter: “Sensing City Scale people movement” and “Movement of Pedestrians/Bicyclists”.

Under “Sensing City Scale people movement” IBM will analyse data on the flow of people to show how people move in the Slakthus area over time by creating heat maps. This analysis will be combined with other data such as public transport capacity, traffic measurements, weather, etc. to see how well the different transportation modes and capacities are optimised in the area, especially during events with a lot of people in motion. The project team, platform for data management, analysis tools and method are all already in place.

In “Movement of Pedestrians/Bicyclists” IBM will measure and study in detail specifically how pedestrians move in the city. A prototype user interface environment has been developed on the Bluemix platform. Sample data sets from relevant data sources have been uploaded into the Bluemix environment and made available for users, including vehicle traffic measurement data, bicycle traffic measurement data, bicycle accident data, and weather data for specific locations in the city. End user functions and graphical visualisation tools have been developed.

Together with the Traffic Administration, a plan for implementing new sensor data sources has been made. There will be 7 video sensors in the city connected via the fibre optic network to the Bluemix platform, which will feed into the traffic planner user environment in Bluemix. These sensors will be able to measure the flow, volume and direction of pedestrians, cyclists and vehicles in the selected city areas covered.

Waste Heat recovery

Fortum’s open district heating (solution 6) will be implemented in two locations. In Västberga, waste heat from data centres will be integrated into the district heating system.The same will be done for waste heat from Supermarkets in Farsta (some 5km south of the Slakthus area). The agreements have been signed and the installation in the Supermarket is completed. Due to delivery problems the heat pump could not be delivered as planned in March, so the installation in the data centre is postponed until June. When the solutions are in operation, the waste heat collected can be distributed into the district heating system and provide heat and hot water to more than 1,000 apartments.

Smart waste Handling

The waste handling system provided by Envac will be completed in June this year, with the terminal and inlets being installed during spring 2017. The different waste types will be separated by tenants into different coloured bags. The tenant places the bags in the inlet, and each bag colour is automatically identified and measured. Data from all six buildings in the project will be collected. The waste is then transported in underground pipes to the terminal. From the terminal the waste bags are sent to the sorting facility, where the different coloured bags are separated for recycling.

The smart waste handling has several benefits. It saves space compared to conventional waste containers, which can then be used for other purposes. The system also brings about benefits for hygiene and reduces bad odours. As the waste is piped to the terminal for collection, traffic for collecting waste at buildings will be reduced, meaning reduced traffic emissions but also less noise at residential buildings.

Building logistics center and delivery boxes

The building logistics centre (solution 2), implemented by Carrier, started in September 2016 with the delivery of windows to Valla Torg. Carrier is together with Skanska discussing which material streams can be best handled by the logistics centre. The construction logistics are part of the production process, so the better production is planned and organised, the easier it is to provide just-in-time deliveries to construction sites. The materials are delivered outside work hours (after 5pm) so that they are available in the next morning at the construction site.

The implementation of delivery boxes (solution 9) by Carrier will be done in three buildings as part of the 2017 refurbishment plan in Valla Torg. Tenants can order packages and other deliveries straight home instead of picking them up from the nearest service point. The delivery from the service point to the building is done by cargo bikes.

Smart Traffic Management

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

KTH has together with Info24 (now Tingcore) developed a smartphone application (solution 10) to study changes in travel behaviour in a way that is more effective and has a greater response rate than traditional travel surveys. This will improve the travel demand management measures. In the same application, information about renewable fuels in Stockholm will be shown. This information contains updated information on where each alternative fuel can be tanked, together with most recent price.

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 during 2017.

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

Communication and marketing

In Stockholm several study visits have been arranged and there is a great 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 the Slakthus area. In spring 2018 an event is planned for tenants in Valla Torg.

All Stockholm partners will produce their own communication activities plan in April, and contribute to an overall communication activities plan for the Stockholm site. In addition, the partners will start producing a marketing plan for their smart solutions as soon as the implementation is completed.

GrowSmarter is a complex project in which many solutions are linked to each other and both planning and implementation must happen in an integrated manner. This is very evident in Valla Torg, where the tenants must first vacate the buildings before the smart solutions can be implemented in and around the buildings. As this process didn’t start as planned in February 2016, but rather in August, we are now in a very hectic implementation phase where everything happens at the same time, as we still need to keep the original timetable. In this blog I will explain in more detail everything that will happen in the next few months to come.

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.

For those of you who didn’t have a chance to read my previous blog posts, the smart solutions for low energy districts will be rolled out in three building zones, namely Valla Torg, Årsta and the Slakthus area (see map here). For an overview of the measures being implemented, click here. In Valla Torg tenants began leaving the buildings in August and the first high-story building has scaffolding (pictured). Work on the façade will start in October. The walls will receive more insulation and new energy-efficient windows will be installed by Skanska. The interior work will also start at the same time. Old pipelines will be removed and new insulated pipelines will be installed. All these measures are part of the energy efficient climate shell (solution 1).

In the private condominia Brf Årstakrönet, the refurbishments (solution 1) and (solution 3) started in January 2016 with the installation of an adaptive control system by Veolia. Veolia will also install photovoltaics (solution 4) on the roofs upon receiving the building permit. The same solutions will also be implemented in the Valla Torg and Slakthus area buildings during later stages of refurbishment.

The real estate administration office (Fastighetskontoret) has made a procurement of a building contractor for Slakthusarea, but the decision has been appealed. As soon as the court has given its decision the work can continue.

Installing smart LED-lighting

The installation of smart LED-street lights (solution 5) was finalised in June in Valla Torg. The adaptive LED-lighting will reduce energy consumption by 50% while still providing the same sense of security along walking and bicycling paths. Each street light features a radar detector that senses movement on the path (Picture). As soon as any movement is detected, the light is activated and the movement is communicated wirelessly by radio to a number of nearby street lights. As a result, cyclists and pedestrians experience normal illumination levels along their entire route. In Stockholm the lights are not fully turned off during periods without movement, but rather dimmed down and then activated to full light as soon a person approaches.

Waste heat recovery

Fortum’s open district heating (solution 6) will be implemented in two locations. Waste heat from Data Centres in Västberga and waste heat from Supermarkets in Farsta (some 5km South of the Slakthus area) will be integrated into the district heating systems. The agreements have been signed and the installations will begin in October-November. When operational, the waste heat collected will be distributed into the district heating system and provide heat and hot water to more than 1,000 apartments.

A smart connected city

In Stockholm the smart connected city will use the extensive fibre optic network provided and administered by Stokab, a company owned by Stockholm City Council. Several Internet of Things applications and solutions can be built on top of the fibre optic network. Together with different departments and city owned companies, we are defining ways to provide higher quality of life for citizens with smart connected solutions in a series of workshops. We will start the process with defining the users’ needs. We have defined three groups of users: inhabitants, visitors and companies. In the Slakthus area we are focussing on visitors and companies, while in Valla Torg the focus is on inhabitants. In my last blog I addressed some of the activities in the Slakthus area, so in this blog I will cover how apartments with simple installations can provide many new functions.

In residential houses, as the tenants change over time, we should install equipment which can be used by several end users and for several purposes. Let’s say we install a movement sensor and water meters in every apartment. If the inhabitant is old, maybe the relatives would like to have a way to monitor her well-being. For example, a simple alarm function could be built and an automatic message sent to relatives when the motion sensor senses the person is inside the apartment, but has not used water for 12 hours. We can also collect water use data and the housing company could, for instance, detect leakages when water is being used and no one is home. If we realise that people use water in different ways, from very little to very intensively, we can create individual water billing so that everyone only pays for the water they use.

IBM, who are responsible for the open consolidated big data platform (solution 8), are involved in two parts of the project: “Sensing City Scale people movement” and “Movement of Pedestrians/Bicyclists”.

In “Sensing City Scale people movement” IBM planned to analyze mobile phone data and create heat maps to show how people move in the city over time. This analysis was to be matched against other data such as public transport capacity, traffic measurements, weather, etc. to see how well the different transportation modes and capacities are optimised in the city. The project team, platform for data management, analysis tools and method are all in place. A subcontractor was identified and final negotiations for delivery of Telco data were in progress at the beginning of 2016, with the project start scheduled for 1 February 2016.

But an unexpected issue arose. Based on a thorough legal assessment of the current Swedish Personal Data Legislation (PUL) and the EU General Data Protection Legislation (EU GDPL), the subcontracted Telco cannot provide the requested mobile telephone data for citizens of Stockholm in a way that would make it useful to the use case defined by IBM Research Dublin Lab. The only legally approved way for getting access to mobile phone trajectory data is to ask the citizens to voluntarily participate in the project and thus explicitly give consent for the project to track the movements of their mobile phones over time.

The merits, challenges and feasibility of this alternative approach will be assessed by the City of Stockholm and IBM, and a decision on whether to attempt this approach - by consent will be made in 3Q 2016.

In “Movement of Pedestrians/Bicyclists” IBM will measure and study in detail especially how pedestrians move in the city. A prototype user interface environment has been developed in the Bluemix platform. Sample data sets from relevant data sources have been uploaded into the Bluemix environment and made available for the users, including vehicle traffic measurement data, bicycle traffic measurement data, bicycle accident data, and weather data for specific locations in the city. End user functions and graphical visualization tools have been developed, e.g. new work project definition, traffic data selection, report generation, and graphical data visualization.

A plan for implementing new sensor data sources in Aug/Sept 2016 has been agreed upon with the Traffic Administration. This will consist of 7 video sensors in the city infrastructure connected through the city fiber optic network to the Bluemix platform. Data from these sensors will be uploaded into the traffic planner user environment in Bluemix. These sensors will be able to measure the flow, volume and direction of pedestrians, cyclists and vehicles in the selected city areas covered.

Smart waste handling

The underground parts of the smart waste handling system (solution 7) provided by Envac will be implemented in October and November (pictures). The terminal and inlets will be implemented during the beginning of 2017. The waste is compacted right below the waste inlet in the storage pipe instead of upon arrival to the waste terminal. The compacted waste allows for smaller pipes and a reduction of the airflow by as much as 50%. These factors together result in a reduction of energy consumption up to 50%. The solution will consume less energy per tonne of collected waste than any other comparable traditional waste collection, including ordinary waste collection vehicles.

Building logistics centre and delivery boxes

The building logistics center (solution 2) and delivery boxes (solution 9) will be implemented by Carrier starting in October and November. The location of the buildings logistics centre has changed and will now be in Slakthus area. Carrier has together with Skanska discussed which material streams can be best handled by the logistics centre. The construction logistics are part of the production process, so the better production is planned and organised, the easier it is to provide just-in-time deliveries of materials to construction sites. Typically the materials are delivered outside work hours (after 5pm) so that they are available the next morning at the construction site. There are several benefits of the construction logistics centre. First, there are fewer materials wasted and damaged at the construction site, along with less traffic to and from the construction site. The construction site can also be kept clean, as the packaging waste is regularly removed. What’s more, production is enhanced as materials needed for work are constantly available and it is always clear where the materials are and how much is in stock.

Delivery boxes (pictured) are installed in the entrance of the refurbished buildings in Valla Torg next to the post-boxes. Tenants 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, together with NOAE (Network of Automotive Excellence) and Global car OEM, is implementing an information system for drivers (solution 10). In Stockholm around ten traffic lights will be equipped with software that can communicate and inform users about the status of the light and when it is about to change. This is achieved through a data connection between the traffic light, the cars’ onboard software and GPS, and a central computer handling the calculations. Through a special device in the car, the driver will 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 for a few months’ time. Effects on travel time and the drivers’ experiences will be evaluated.

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 will soon be installed in Årsta. The location has been selected and the charger has already been delivered. The normal charging stations will be installed in Valla Torg, the Slakthus area and Årsta.

The first refuelling station (solution 11) is up and running (picture). The filling station in Årsta is expected to be established in the beginning of 2017.

Citizen engagement

A citizen engagement event was organised in Valla Torg in September. The event was very successful with around 500 visitors and positive feedback. The event was also the launch of the refurbishment in Valla Torg, and the audience had the opportunity to get information both on the GrowSmarter project and the different smart solutions from our partners, and to visit the exhibition apartments.

Those of you who have read my previous blogs will know that as part of the GrowSmarter project we are developing the City of Cologne’s open data platform www.offenedaten-koeln.de to include new datasets to help improve traffic management.

Cambio carsharing and KVB (both GrowSmarter industry partners) have now provided datasets on the locations of the rental cars/ rental bikes, respectively as well as their actual positions when in use, so we have both static and dynamic data now available for these services.

• Car rental (cambio car-sharing) dataset, can be accessed here: www.offenedaten-koeln.de/dataset/og_group_ref/1613

• Bike rental (KVB) dataset, can be accessed here: www.offenedaten-koeln.de/dataset/og_group_ref/1314

Our partner [ui!] – the urban institute is now busy implementing these datasets into the cockpit of the open data platform.

Some 25 Apps have already been developed based on the Cologne open data platform which shows a wide range of different use cases and we hope that by adding richer datasets will open up new value chains that spawn innovative and smart solutions which in turn boost sustainable modes of city living and working.

So now we made the first step in motivating the people to change their behaviour. It’s so easy to check for the next cambio station or the next bike to use!

Curious how it works? Check at www.cambio-carsharing.de/koeln and www.kvb-rad.de/de/koeln/ about the terms and conditions.

Action area 3: Sustainable Urban Mobility

Urban planning of mobility hubs – when do public and private interests overlap?

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

In our first blog we mentioned our plans to develop mobility hubs at strategic points throughout the Mülheim area and the Stegerwaldsiedlung (no 2 on the map), where intensive building refurbishment is taking place as part of the GrowSmarter project. It has taken a bit of time, but now we have some new updates to share!

General overview

As the Stegerwaldsiedlung, directly borders Urban district 1: downtown (high traffic levels), we have built up a route of several mobility points which run from Messe-Deutz station (see green circle on map) directing traffic North through the Stegerwaldsiedlung and the wider Mülheim district. Urban mobility measures (smart solutions 10-12: Smart traffic management, Alternative fuel driven vehicles and Smart mobility solutions) to be rolled out in areas 1-3 on the map are described in brief below. More detailed information on the planning can be found here

Übersichtsplan ©Stadt Köln

Charles-de-Gaulle-Square

Located to the North of Messe-Deutz station, the Charles-de-Gaulle Square lies between Auenweg and the river Rhine and is well connected with trams, regional trains, as well as, the high-speed ICE trains for long-distance travel.

Parking lots currently for cars (bikes to follow) to the East of this square are currently rented out privately, while those to the West are managed by the City. The latter is classified as fiscal property, which is not under public law, and provides enough space for all modules of mobility hubs.

Our GrowSmarter partners in Cologne, Cambio and Ampido submitted applications with the City administration at the beginning of the year to manage some of these parking lots. These applications have been accepted subject to conditions, mainly related to design elements.

Ampido will manage five parking lots using the online management of parking space. Cambio requested five lots, two for electric vehicles and three for conventional vehicles. It is also envisaged that KVB will set up a public electric charging station for two electric vehicles.

KVB AG will install a bike rental station in the immediate vicinity of the station providing both electric and pedal bicycles. The exact location has yet to be determined.

Stegerwaldsiedlung

Moving over to the Stegerwaldsiedlung, the mobility hubs here will be built on property owned by GrowSmarter partner DEWOG, which is also closely located to Cologne’s public transport system; station stop Stegerwaldsiedlung offers connections straight into the city centre.

Arrangements to accommodate all of the proposed mobility solutions within this hub will be managed by DEWOG and the other partners. Preliminary consent for this process has been signed by DEWOG.

As large-scale retrofitting of the buildings in Stegerwaldsiedlung are underway to improve energy efficiency, as such the outside area is partly needed for the building site. Therefore, implementation depends on the progress of these renovation activities.

Current plans are shown below with the exact allocation of the industrial partners has yet to be determined.

The Köln-Mülheim station forecourt

Recently refurbished as part of the Mülheim 2020 project, the forecourt of the Köln-Mülheim station sees many passengers pass through every day on their way to and from the city either by bus or the city light rail network, provided by KVB. The station is a connecting point for commuter trains coming from outside the city and regional trains.

This area forecourt belongs to the Deutsche Bahn (DB) and is currently managed by a DB AG subsidiary, car-charing company Flinkster.

Based on the licensing agreement concluded between Deutsche Bahn AG and the city of Cologne, DB AG has agreed to provide Ampido and Cambio with the use of two parking lots each. The exact allocation has still to be agreed upon with DB AG.
