 Technical room, upper floor2,7 × 2,5 × 4,15 m
 Test room, upper floor2,7 × 7,3 × 4,15 m

Building Services :

The technical room on the ground floor houses the building services equipment for supplying the experimental building. This includes the indoor units of the two cascaded heat pumps, the buffer storage tanks, and the distribution piping. The technical room on the upper floor is the installation location for the two outdoor units. A PV system with 7.7 kWp is installed on the roof.
The handling building is unconditioned, except for frost protection in the ground-floor technical room.
