Publication of the final report The project "Energy Sufficiency - Strategies and Instruments for a Technical, Systemic and Cultural Transformation to Sustainably Limit Energy Demand in the Consumer Field of Building/Housing", funded by the BMBF, was successfully completed at the end of 2016. The project investigated how energy-sufficiency-related everyday routines, social practices and lifestyle aspects can be reconciled with the requirements of a [...]

In contrast to combustion engines, the amount of energy required to produce the batteries plays a greater role in electric cars. According to the IFEU Institute in Heidelberg, CO2 emissions can be estimated at around 125 kg for one kWh of battery capacity. The production of an electricity storage unit with 24 kWh thus generates about three tons of CO2. In contrast, the resulting [...]
The study "Method development for the description of target values for primary energy consumption and CO2 equivalent of building constructions for linking with property allocation and quality assurance up to design planning" of the RuhrUni Bochum under the direction of Prof. Dr. Annette Hafner has now been published and is available for download.

They are highly efficient, low-emission and quiet: New fuel cell heating units generate heat and electrical energy as mini CHP units with over 90 percent efficiency. They have been tested extensively in detached and semi-detached houses, and their function and design have been improved step by step. The first systems are already on the market. They can be operated with natural gas as well as [...]
"BISKO" is neither a sausage nor a new chocolate bar, but the new "Municipal Accounting Standard". After four years of development, a methodology paper is now available that provides clear accounting rules for energy and greenhouse gas balances for municipalities in Germany. In a lengthy consultation process, coordinated and technically led by ifeu Heidelberg, [...]
The EEG is supposed to achieve the goals of the Paris climate summit. But at the rate of expansion to date, according to a study by Berlin's HTW, we will have to wait until 2150 for Germany to switch completely to renewable energies.
On 30.6. the field test started in Herten, North Rhine-Westphalia. For one year, scientists coordinate the operation of three combined heat and power plants with the use of three heat pumps, a PV system, a large lithium-ion storage unit and a private electric storage heating system to balance the PV and wind feed-in.
Project outlines, especially for public buildings, municipal properties and urban districts, can be submitted until 29 July as part of the new funding initiative "Solar Building & Energy Efficient City".
The SOLAR.shell research project clarifies how the yields of photovoltaic components on building facades can be increased by up to 50 percent compared to vertically installed PV elements by tilting and turning the elements. Read more here at Detail: Article
Several federal ministries launched new funding programmes and research initiatives in April. The common goal is to promote affordable and climate-friendly construction in order to advance the energy transition through energy-efficient and climate-friendly buildings. The building sector accounts for around 40 percent of Germany's final energy consumption and about one third of CO2 emissions. At the same time, the potential for energy and CO2 savings [...]
The new housing development "Ludmilla Wohnpark" was built in Landshut with more than 180 residential units in plus-energy construction. Five single-family houses, two semi-detached houses, six terraced houses and eight multi-family houses with a total of 55 apartments were built on a plot of around 7,300 square metres. Researchers from Munich University of Applied Sciences and the Technical University of Dresden are evaluating the quarter [...].
With more than 1,700 completed buildings, SolarActiveHouses are no longer a marginal phenomenon. What has been missing so far is a scientific evaluation of this heat supply concept. To this end, researchers have measured nine solar houses over several heating periods. The responsible project manager Gerhard Stryi-Hipp presented the interim results at the OTTI symposium "Thermal Solar Energy". Read the further in the [...]
