About Testbed EM
The buildings are heated by preheated supply air. Hot water and heat are generated via heat pumps connected to 12 boreholes with a total length of 3600m, and several boreholes have fiberoptics installed for temperature measurement longitudinally.
The roof surfaces are covered by 1150 sqm of photovoltaic panels. There are a total of 50 sewage heat exchangers installed, both vertical and horizontal. Extract and supply air can be adjusted in all apartments. Hot water, electricity, CO2 and light are measured in all apartments. Regulation and control systems are possible to influence for research purposes. The buildings are plus energy buildings.
