ABSTRACT
An earth-air heat exchanger (EAHX) has been implemented in a low-energy office building in Kortrijk, Belgium. An extensive monitoring campaign was conducted to define the energy consumption in the building and the contribution of the EAHX to energy savings. This paper presents the results of the measurements and compares the measured performance of the EAHX with the predicted performance with a ID calculation method and a simulation model for 3D transient heat transfer. Results are also compared to the building energy use.
