Signhild Gehlin, Operating Agent of Annex 52: there is a beauty in efficient energy use

Geoenergy expert Dr Signhild Gehlin describes it as elegant when thermal energy is recycled from the surrounding environment of a building. “The energy that is utilized locally is resource-efficient and is a give-and-take from what is already there by nature”, she states. As the Operating Agent for Annex 52, Signhild has the opportunity to dive into the depth of geoenergy by finding a systematic way to measure and analyse the efficiency of ground source heat pump systems.
