Monitoring of real GEO-HP-TABS (Geothermal Heat Pumps connected to Thermally Activated Building Systems)

This report presents the analysis of measurement data collected on five different buildings in the frame of WP4 (“Monitoring of real GEO-HP-TABS”) of GEOTABS project. These office buildings are located in Germany (buildings A and B) and in Belgium (buildings C, D and E). First of all, the buildings architecture will be presented. The control strategies of the HVAC systems used in these buildings will also be described. Then the energy performance of each building system will be assessed and discussed (on seasonal, daily and monthly bases). The evaluation of the energy performance will be based on monitoring data collected on the geothermal heat pump – TABS systems and other HVAC components. An analysis of the long-term thermal comfort will be presented. Finally, an economic and environmental analysis will be performed for two of the buildings.
