How Local Authorities and Cities Can Reduce Costs and CO2 Emissions

In some schools, the heating runs at full blast even during the holidays. Such incorrect settings in heating systems in public buildings can be avoided with intelligent measuring systems. Researchers have tested this approach in 25 buildings in Bottrop. Other cities and local authorities can now also benefit from their findings.

Customizing Systems for Renewable Heat Supply

Researchers have analysed the heat consumption of 797 companies in Germany. The findings will make it easier for companies to plan their heat supply with fluctuating producers such as solar thermal energy and with heat pumps in the future.

While a large proportion of electricity in Germany (around 50 %) is already generated from renewable energy, the heating and cooling supply is still largely based on fossil energy carriers. Successfully transforming the heating sector may prove a key contributor to transforming the energy sector.
