Résumé

Long-term studies of GSHP heating and cooling systems for six different buildings (commercial, institutional and multi-family buildings) have been conducted in Germany by SIZ energy+. Three of them are equipped with borehole heat exchangers and the others use energy piles as a heat exchanger. The paper deals with a demonstration of the investigated buildings, the measured values and performance and the obtained results that include important findings and experiences, problems encountered and possible preventive measures to avoid mistakes.After ten years of operation it can be stated that the systems work and achieve their planned efficiency but require constant control and regulation to avoid faulty operation. An analysis of the implemented control strategies shows that, for all these heating and cooling systems, holistically coordinated control strategies that are verified during commissioning are required.
