Amsterdam Westerpark With 600 residential units as a contiguous settlement, the largest settlement for cyclists in the world. The residents organise their everyday life without their own car. This saves the construction and operating costs of the expensive underground car park and it enables the use of the open spaces for purposes other than parking private cars, which do not drive to over 90% but take up space.

Stadtwerke Ludwigsburg-Kornwestheim is building one of the largest solar thermal plants in Germany with a collector area of over 10,000 m². The way is clear for another forward-looking project in Ludwigsburg: Stadtwerke Ludwigsburg-Kornwestheim GmbH (SWLB) has won the funding call for municipal climate protection model projects as part of the national climate protection initiative of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety in Berlin.
Their funding application for the SolarHeatGrid model project for the 'construction and connection of one of the largest solar thermal plants in Germany to an optimised heating network', in which the City of Ludwigsburg is involved as a cooperation partner, was approved. The official handover of the Municipal Climate Protection Model Project grant to Bodo Skaletz, Managing Director of SWLB, took place on 12 May 2017 by Rita Schwarzelühr-Sutter, Parliamentary State Secretary of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety, in the presence of the Lord Mayor of the City of Ludwigsburg and Chairman of the Supervisory Board of SWLB, Werner Spec, and the Lord Mayor of the City of Kornwestheim and Deputy Chairman of the Supervisory Board of Stadtwerke.
"In terms of the amount of funding, our solar thermal project is the front-runner in the ranking of the seven projects that were also approved. The federal government is contributing 10.4 million euros to the realisation of Ludwigsburg's large-scale project, which should inspire imitation throughout Germany," says a delighted Bodo Skaletz, Managing Director of SWLB.
"This renewal of the district heating network with solar heat is particularly forward-looking with regard to the feasibility of municipal heat supply with renewable energies. Swapping fossil for renewable - it works. I congratulate Ludwigsburg on this major high-tech piece of the puzzle, also in terms of CO2 savings and improved energy efficiency," confirms Parliamentary State Secretary Rita Schwarzelühr-Sutter.
"The 'SolarHeatGrid' is an important building block in the implementation of our overall energy concept for Ludwigsburg," explains Mayor Werner Spec. "We are thus significantly expanding our heat supply on a renewable basis and linking it across municipal boundaries. This is entirely in the spirit of sustainable settlement development: as cities, we must continue to commit ourselves locally with all our strength to environmental and climate protection."
The official start of this lighthouse project is 1 June 2017. The model project is scheduled to take a total of three years. As part of the project, the existing Ludwigsburg district heating network, which already provides heat for large parts of the city using mainly renewable raw materials, will be merged with the Rotbäumlesfeld, Technische Dienste Ludwigsburg (Gänsfußallee 21) and Kornwestheim-Nord networks, which are currently still supplied with fossil fuels. The construction of the solar thermal plant in connection with a large heat storage tank, which is to be built at the location of the CHP plant, will additionally feed high-quality, regeneratively generated heat into the expanded interconnected grid. This will further increase the amount of heat from renewable energies. With the help of the heat storage facility, the energy generated will also be available when there is little or no solar radiation.
The base load heat of the fossil-fuelled heating centres of the individual grids can thus be replaced by the largely regeneratively generated heat of the expanded interconnected grid. Approximately five kilometres of new district heating pipes will be laid over the next three years to connect the solar thermal system and the interconnected grid. In addition to the CO2 savings that will be achieved through the growing share of renewable energies in the expanded district heating network, the declared goal of the large-scale project is to increase energy efficiency. "In order to ensure that energy is used as efficiently as possible, it is not only the heat generation and distribution by SWLB that is decisive, but also the consumer side," Skaletz explains and adds: "As part of the network interconnection, measures are therefore to be implemented to reduce the so-called return temperatures, on which the performance of our district heating network depends to a large extent."
SWLB submitted the funding application in November 2016. The project aims to increase the share of renewable energies in the district heating network and to actively promote local climate protection and the energy transition at the local level by reducing CO2 emissions.

In the 2019 national competition, the focus is on existing buildings and inward growth: How can existing spaces be optimally utilised in times of scarce building land? How can innovative living spaces be created by converting existing uses? The 2019 state competition is looking for exemplary examples - in the city and in the countryside - that utilise all possibilities for reactivating existing buildings and were realised between 2014 and 2019.
The Bavarian Housing Prize is an honorary award. The award-winning participants receive a certificate and the award signet for the Bavarian Housing Prize made of Nymphenburg porcelain.
Project partners of the EU project NETfficient take stock and publish manual in January 2019
Over the past four years, the power grid on the North Sea island of Borkum has served as a real laboratory for testing elements of a future-proof energy system. Central to this was the development of energy storage systems and their networked operation within a virtual power plant. The measures were funded by the EU project NETfficient from January 2015 to December 2018. 13 partners from 7 EU member states worked together.
Forty private houses, five large buildings, part of the Borkum street lighting and the temperature control of the Borkum Seawater Aquarium were connected to PV and energy storage systems, which range from lithium-ion batteries, supercapacitors and recycled old batteries from electric vehicles to hydrogen storage and low-temperature water storage. A 1 MW / 500 kWh large-scale storage system consisting of lithium-ion batteries and supercapacitors was also used in the medium-voltage grid. All these storages and generators were connected to the so-called Energy Management Platform (a Distributed Energy Management System or DERMS), which is the central element of NETfficient. The Energy Management Platform allows the automated operation of the generators and storages and optimizes the energy consumption on the one hand and allows the provision of system services on the other hand.
The various visits to the island of Borkum were enriching for all project partners, who gained insights into life and living there, as well as into the interests and concerns of the island's inhabitants. They found an island community that has an above-average understanding of the challenges of the energy transition and climate change and that has its sights firmly set on the goal of becoming climate-neutral and emission-free by 2030.
On a technical level, this was an extremely complex project that required close coordination between the individual partners, most of whom did not even know each other before the project began. Participation in the project allowed partners from academia and research, industry and SMEs to deepen and exchange their knowledge and skills in a wide range of areas such as energy storage, power electronics, network technology, energy conversion and software. Several partners were able to increase the technological maturity of their products and improve their offer to customers within the framework of the project. For some, the project collaboration led to new orders or projects. Project coordinator Ayesa Advanced Technologies SA (Spain) comments:
"NETfficient was a key project for Ayesa's innovation strategy. It allowed the company to develop new energy solutions with outstanding market potential and established strong collaborations with European partners in the energy and storage value chains. We thank all NETfficient partners for their intensive work on this ambitious project and great community spirit in working towards the project goals."
The most important findings from the project are now being summarized in a handbook, which will be published in January. It can be pre-ordered by emailing netfficient.project@gmail.com.
Further information on the project can also be found at www.netfficient-project.eu. In NETfficient, the Steinbeis-Europa-Zentrum took over the administrative and financial project management, the dissemination and exploitation of the project results, the communication and supports the market introduction.
NETfficient is coordinated by Ayesa Advanced Technologies S.A. in cooperation with 12 partners: Center for Advanced Studies, Research and Development in Sardinia; Department of Electrical and Electronic Engineering of the University of Cagliari; Fraunhofer Institute for Solar Energy Systems ISE; PowerTech Systems; Schneider Electric GmbH; Steinbeis-Europa-Zentrum; Swerea IVF (from ; Vandenborre Energy Systems NV; Williams Advanced Engineering; Wirtschaftsbetriebe der Stadt Borkum GmbH; Zigor Research&Development; and follower-partner Ayuntamiento de Santander City Council's Information and Communications Department.
