Conclusion of IEA Task on the Topic of Lighting
“Lighting Must Be Designed with People in Mind”

Scientists from 17 different countries have conducted research as part of the International Energy Agency’s (IEA) project on “Integrated Solutions for Daylighting and Electric Lighting” (IEA SHC Task 61/EBC Annex 77). Task manager Jan de Boer explains why it is not only the technology that matters.

Climate-Smart Behaviour during the Pandemic
These Ventilation Concepts Reduce Aerosols and Save Energy

A team of researchers working on the MinInfekt project is investigating how indoor air hygiene can be improved in existing buildings. Initial interim results provide recommendations for effectively and practically reducing the risk of infection in classrooms, offices, etc.

Finals in Wuppertal
Programme published: Solar Decathlon Europe 21/22

On the Solar Campus in Wuppertal 18 building models and concepts will soon become reality. As fully functional houses, they will form the centrepiece of the finals of the BMWi-funded European university competition for urban building in June 2022. More Details and the programme are now available.

Unique in Europe
A Climate-Neutral Container Terminal Is Being Built in the Port of Duisburg

Where hard coal was once stored, a sustainable energy system is now being established. On a former coal island, hydrogen-based energy will be generated and stored. Researchers are translating their theoretical concepts into practical applications at the container terminal.

Electrolysis Is More Efficient in Esslingen

The electrolysis system recently installed as part of the “Neue Weststadt” lighthouse project is expected to be 25 % more efficient than conventional systems. Such projects demand both technical expertise and a great deal of commitment from their partners.

Statistical records of buildings in Germany
Database Closes Knowledge Gap about Non-Residential Buildings

From a simple warehouse to a highly automated industrial facility: many kinds of building fall under the definition of “non-residential building”. But how many of these buildings are there? And what condition are they in? How high is their energy consumption? A new database is now providing answers.

Connected City
Living Lab for the Energy Transition DELTA Launches in Darmstadt

In an urban environment, there are many approaches to reducing CO2 emissions in the buildings, residential, and mobility sectors. If these sectors were to be combined and then optimized, the emissions reductions would be even greater. This is the idea behind the DELTA research project.
