Stockholm blog #3: putting smart solutions into practice

What is a demonstration site, if there is nothing to demonstrate? Why does it take so long to get things implemented? Isn’t the technology already there?

These are important questions for a Site Manager to handle and find answers for.

Now that many of the GrowSmarter smart solutions are entering the implementation phase, I will shortly summarise the experiences from the preparation and planning phase.

I will also give an update on the implementation status of the smart solutions and how they are being rolled out.

Action area 1: Low-Energy Districts

Preparation and planning; what have we learnt?

In Stockholm a range of smart solutions for low energy districts, as described in my previous blog post, will be rolled out in three building zones: Valla Torg, Årsta and the Slakthus area (see map).

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

Preparation to implement our numerous energy efficient measures started quite some time ago, even before our GrowSmarter application was submitted back in May 2014.

One key issue was to decide the baseline; what can be done in older buildings and how much energy could each measure potentially save? For this purpose a consultancy firm was appointed; they helped us to assess and identify which measures would be most suitable. This gave us a good starting point for implementation, however the order in which they would be implemented, had to wait until we had our refurbishment plan in place.

Our refurbishment plan not only needed to detail construction costs and time and but also address simple questions like: Does the smart solution need electricity, data connection, wireless data transmission possibilities? As such, several meetings bringing together construction planners and industrial partners were held starting from March 2015 to February 2016. This extensive preparation and planning work was vital to ensuring that all the necessary specifications were included, to be sure that everything will work the way that it should.

Key learning: is to include smart solutions within the general planning process and to avoid implementation becoming separate to the actual construction process. This is the approach we have taken in GrowSmarter, so when an electrician or plumber is doing his/her work, (s)he is also implementing GrowSmarter solutions.

Implementation: efficient & smart climate shell refurbishment

Valla Torg (building zone #1): we are about to start with the energy efficiencies and solution 1 (smart climate shell refurbishment) of the residential building in Valla Torg together with Skanska. More update on this in my next blog!

Årsta (building zone #2): In the private condominium Brf Årstakrönet the activities solution 1 (Efficient and smart climate shell refurbishment) and solution 3 (Smart energy-saving tenants) started in January 2016. Veolia has installed a temperature sensor in every apartment, which logs information about indoor temperature levels. The target is to stabilise indoor temperature as far as possible, by controlling and steering heat into the building. In the diagram below, you can see information collected from the building to be able to optimise its energy use.

The yellow line indicates the indoor temperature and the blue line the outdoor temperature. Traditional temperature regulation is based on outdoor temperature which means that it sends hot water (indicated with the purple line) at night into the building regardless of the need. By controlling both indoor- and outdoor temperature, you can postpone the need for hot water, and lower heating costs.

Veolia has also started preparations to install solution 4 (photovoltaics) on the roofs of the building together with a new innovation developed in Sweden called the Energy Hub. The energy hub controls energy flows between solar cells, energy storage (battery), local loads and the grid. Veolia will also implement a module called Adaptive Current Equalisation (ACE). The ACE technology continuously monitors the grid currents. If one of the three phase currents exceeds a pre-set threshold, available energy from the other two phase conductors are used instead. This prevents overloading of mains fuses and can even allow the supply capacity to be reduced and hence the associated grid fees.

Slakthus (building area #3): Refurbishment of the Slakthus area buildings will start in May/June.

The picture below is from a study visit where Royne Julin from the Stockholm City Real Estate Administration is presenting the refurbishment and energy efficiency measures in the buildings for an international group of visitors.

Installing smart LED-lighting

In April this year, we started with the installation of solution 5 (smart LED street lights) which will be finalised by the summer in Valla Torg.

The LED street lights, 25 Luminaires installed by the Stockholm City traffic Department will be an opportunity to showcase the benefits of open standards in enabling interoperability within intelligent lighting systems.

Using integrated light controllers and associated software, the Luminaries will be connected to outdoor Wi-Fi networks (via the radio frequency (RF) mesh network) and run by an automation system (Power-lin communications (PLC) networks) to reduce energy usage, operational costs and improve safety.

The potential exists to expand the RF mesh network to connect other city devices such as traffic lights, meters and different sensors. This possibility will be explored in more detail as part of the measure traffic posts as base of sensors.

In the picture above, Anders Hedlund from the City of Stockholm’s Traffic Administration is presenting smart LED lighting solution to an international group of visitors participating in the Eureka Innovation week in Stockholm. The building in the background is one of the buildings to be refurbished in Valla Torg.

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 captured and distributed via the district heating system

• in Farsta waste heat from supermarkets (some 5km south of the Slakthus area) will be used. As soon as agreements are signed, implementation will start.

Here Mr Hedman, from Fortum is presenting the open district heating solution. More information about this solution can be found here.

Big data management

In March, IBM, which is responsible for the open consolidated big data platform (solution 8), has conducted a Design Thinking workshop with the city’s traffic department to define which users to focus on and which problems to address.

Work continues with Stockholm’s Traffic Department and STOKAB/St Erik Communication to demonstrate the open data analysis and innovation platform to connect IOT devices, existing traffic data sources, as well as, assessing the need for new potential sensors e.g. video sensors.

Action area 3: Sustainable Urban Mobility

A grand opening...!

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

The delivery boxes (solution 9) will be installed alongside the refurbishment in Valla Torg.

A survey of travel behaviour (solution 10) in Valla Torg has been done. The next step is to study two other locations in Stockholm and analyse reference groups.

As part of the GrowSmarter project, Fortum will install 10 charging stations and one fast charger (see image left - ©Stockholm)(solution 11). The fast charger will be put up in Årsta. The other charging stations will be put up in BRF Årstakrönet, Slakthus area and Valla Torg. The implementation has started.

Contracts for the first two refuelling stations (solution 11) have been signed and the third is on its way. The filling station in Årsta is shown in the picture.

Study visits in new information centres

Information centres in Valla Torg and Slakthus area for citizens and other interested visitors are now open!

The grand opening was held in 28 April when a study visit was organised for an international audience from Asia, Europe and North America.

A second study visit took place on 19 May with visitors from the different departments of the City of Stockholm.

The picture (Information centre ©Stockholm)is taken from the information centre in Valla Torg.

Cologne blog#3: Urban planning of mobility hubs

Find out how we are working with our industry partners to build up a route of several mobility points from Messe-Deutz station North through the Stegerwaldsiedlung and the wider Mülheim district.

Our data platform continues to be developed and has already stimulated local entrepreneurs to create some 25 Apps.

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 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:

• Bike rental (KVB) dataset, can be accessed here:

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 and 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

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.

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.
