Making the Full Life Cycle of Buildings climate-smarter

Grey emissions can be measured and limited more effectively: researchers in the KEA-Bauwerk project are developing basic principles and tools to reduce energy consumption and CO2 emissions in the life cycle of buildings. They are identifying practical data and benchmarks, for example.

Information event
Europe-wide ideas sought for more sustainable cities

The European partnership "Driving Urban Transitions to a Sustainable Future" has published its first call for funding. 

Based, among other things, on the European Green Deal and with a view to the commitments under the Paris Climate Agreement, the EU wants to significantly reduce greenhouse gas emissions by 2050 (symbol image).

Launch of the Living Lab for the Energy Transition GWP
New: Large-Scale Heat Pumps in Germany’s District Heating Networks


A large proportion of Germany’s CO2 emissions can be attributed to the supply of heat. Large-scale heat pumps powered by greenhouse gas-free electricity could help the country to reduce its CO2 emissions. In the living lab for the energy transition focused on the installation, operation, monitoring, and system integration of large-scale heat pumps (LHPs) in district heating networks, these systems will now be connected to district heating networks at various types of location.
