    Goal: Climate-neutral, affordable housing

    The cities of Stuttgart and Überlingen are collaborating together in the “Urban District 2050 – Solving Challenges Together” research project. The project goal is to remodel and develop two districts to create affordable, climate-neutral housing. The two municipalities are tackling the tasks in different ways. Their systematic approaches will enable, however, the experience gained by the respective demonstration districts to be also utilised by the other city.  more...
     

    New Energy Research Programme published

    The German cabinet has passed the new, 7th “Innovations for Energy Transition” Energy Research Programme. The programme replaces its predecessor from 2011. Content-wise, the programme builds on the successes of recent years, sets new courses and defines focal points for research funding and innovation policy in the energy sector. For the years 2018-2022, the German Government is budgeting 6.4 billion euros for energy research.  more...

    Hydrogen for the urban energy transition

    A new, almost climate-neutral urban district is being built on the site of a former freight yard in Esslingen. Over a period of five years, scientists in the planned Neue Weststadt district are experimenting with an innovative energy supply concept with which electricity surpluses from intermittent renewable energies will be converted into hydrogen, stored and, if necessary, returned to the grid. The district will also serve as a real-world laboratory for the system-supportive coupling of the heating, cooling, electricity and mobility sectors.  more...
     

    CIGS thin-film modules beautify house walls

    In order to achieve the goal of meeting Germany's energy demand almost completely with renewables by 2050, it is planned that facades and partially shaded surfaces should also be used for generating electricity by photovoltaic means. The modules that can be used for building-integrated photovoltaics (BIPV) have to meet considerable requirements in terms of their appearance, performance and costs. Experts have summarised this need for action in their recommendations for the German federal government's 7th Energy Research Programme.  more...
     

    Photovoltaic elements for facades and flexible roofs

    Modern building facades can do more than provide insulation and outer envelopes for buildings. New photovoltaic modules give designers considerable scope when designing the colour of facade surfaces. Unlike standard solutions, such energy facades make a considerable contribution to improving the energy balance of buildings. Standard silicon, thin-film and organic PV elements can be used.  more...
     

    Developing multifunctional façade elements

    As the outermost layer of the building envelope, the façade performs numerous functions. They are to be intelligently combined to create a system that permits the application of cost-effective, multifunctional façade systems. To do this, scientists are developing a façade element with integrated organic photovoltaics, textile sun protection, a sustainable insulating material and the sensors necessary for control. The next step is to test the elements on the south façade of a multi-storey residential building.  more...
     

    Heat supply – solar-active and grid-connected

    Since autumn 2016, a new passive house residential neighbourhood has been under construction at the science and technology site Berlin Adlershof. It is connected to the return feed of an existing district heating network and feeds in the solar heat generated inside the district. The project is the subject of extensive research.  more...

    Testing climate-neutral districts in the real-world laboratory

    How can energy efficiency measures and the utilisation of renewable energy sources enable districts to get by with virtually no fossil fuel? How can smart networking of power, heat and mobility be achieved? Scientists and other stakeholders are investigating these questions in six flagship projects. Initial results and local challenges were outlined by the research teams in a panel discussion at the Berliner Energietage conference.  more...
     

    Smart Green Tower becomes an energy producer

    The Smart Green Tower is being built in the city of Freiburg. The 51-metre-high building will provide living, residential and working space. Depending on the solar radiation, a building envelope made of photovoltaic modules generates more energy via the photovoltaic system than can be consumed directly. In order to utilise the surplus electricity, the designers are using a flexible internal energy storage system with lithium-ion batteries.  more...

    Optimising heat pumps for multi-family homes

    Solutions for the application of low-exergy systems are being developed to supply heat to existing multi-family homes. This building services equipment includes electric and gas heat pumps as well as heat transfer and ventilation systems. Different system concepts are assigned to different building types and refurbishment processes and then evaluated. The aim is to realise and evaluate the developed heat pump systems and components in exemplary refurbishment projects.  more...
