Background Information

Green with IT Berlin-Brandenburg is a network of companies focussed on developing innovative products and solutions in the energy-efficiency field. The aim of the “green with IT Berlin-Brandenburg” network is to build up a central platform to promote cooperation and collaboration on projects involving energy harvesting, green technology, consumption transparency, building assistance, and browser apps in residential and non-residential buildings.

History of the Pilot Project

Added value from energy efficiency benefits tenants and landlords alike. And the world speaks IP, so everyone benefits from data security. Since May 2016 the implementation phase of the green-with- IT project ‘My Flat’ was launched in various residential districts of municipal and cooperative housing companies in Berlin, Brandenburg, and Sachsen-Anhalt. Nicole Jaegers, CEO of GWG Lübben eG, said “We are taking a new approach to the development of lucrative added value by focusing on low-investment, highly efficient measures in the spirit of the BBFA’s ALFA philosophy. Like ladder rungs, we can achieve clearly defined, successive efficiency steps to improve heat balance and tenant communication.”

These ‘ladder rungs’ have been tried and tested in long-standing pilot projects: flow limiters, self-learning single-room controllers, IP network controllers, smart meter gateways, scalable energy management software and IP-based neighbourhood management. “Smart” applications support the transparency of the most important electricity and heating data for tenants, caretakers and house technicians. They provide the management board with important data for optimising energy efficiency as defined in the DNK “Sustainability Code of the Council for Sustainable Development”. Daniel Schulz, Managing Director of ABG Paradies in Berlin, says: “There are valid reasons for submitting a DNK Declaration of Conformity in the annual report. Our approach to "innovations” is, among other things, self-generation of transparency data for heating energy. To this end, we replace all HKV components with innovative hardware. This then feeds the new fibre-optic networks via smart meters with permanent energy data. Costs for the expensive purchase of such data by third parties are avoided because a Smart Meter Gateway can bridge TV and telecom networks in the house”.

In Lutherstadt Eisleben, the local ‘wobau’ project operates in a similar vein. Elements of measurements of reference buildings are used to evaluate pilot results. All measures are explained at tenant meetings and the data protection is based on the certification requirements of the Federal Office for Information Security (BSI). Marc Reichardt, Managing Director of Wobau Eisleben, says: “We take every step together with our tenants after careful preliminary testing. We are looking forward to the first results, which we are expecting in the summer of 2017.”

The test bed will be expanded by a complete health care camp in Berlin and will thus be able to collect comparative values from the commercial sector. The founder of the Green with IT network, Jörg Lorenz, says: “In the German capital region, energy efficiency technologies have been closely adapted to the needs of the housing industry. The universities and business development organizations supported us. Here, the efficiency of the system is developed into a global export warehouse. This creates reliable alternatives to mere insanity.”

Impact on Climate Stability

We contribute to improving the energy and climate protection balance with our innovative approaches. More than ever, economic climate protection plays a key role in the future viability of building stock. It is important to agree on a set of goals. Only if these goals are adequately balanced can living in the long term remain a sustainable asset. The public, cooperative, private and ecclesiastical housing companies in the Berlin-Brandenburg- based Housing Association (BBU) thus stand for sustainable climate protection. Climate protection agreements are at the centre of the BBU climate protection strategy. As dictated by the CO2 reduction initiative of the Berlin economy, which the BBU developed as an alternative to a solar power system regulation in 1997, and a further successful climate protection agreement over the years 2006 to 2010, the BBU again signed a framework agreement with the state of Berlin in 2011. A “CO2 cover” has been introduced, allowing the member company to set individually agreed CO2 limits for the emissions in the housing stock from space heating, hot water consumption and home electricity by 2020. In the years 2011 and 2012 voluntary climate protection agreements were concluded on this basis between the municipal housing associations and the state of Berlin. These housing companies have agreed to reduce the respective CO2 emissions per apartment to 1.12 to 1.50 tonnes per year by the year 2020.
