Abstract
The use of ground-air heat exchangers (GAHX) in a ventilation system is gaining recognition as a low or zero carbon ventilation strategy. However, there is very limited research and published data on the thermal performance of GAHX under UK climate. This research project currently undertaken at the University of Brighton aims to fill this gap in knowledge. The research evaluates the thermal performance of the GAHX - so called Earth tube - under different configurations, climatic and operating conditions in the UK. Thermal simulations have been carried out, using validated thermal models developed by others and the ground temperature and climatic variables established from this research, to predict the daily air supply conditions from GAHX and to evaluate the annual energy gain/saving potential. A low rise office building located in Brighton, Southeast of UK, is used as a case study to demonstrate the potential and effectiveness of the GAHX. The issues related to the application of GAHX and the further research are discussed.
