Abstract This paper evaluates the technical and economic performance of an experimental building-integrated earth–air heat exchanger (EAHE) system in arid regions during winter. Heating, ventilation, air conditioning (HVAC) systems can account for up to half a building’s energy consumption, making them critical focus conservation. The EAHE was tested its ability maintain indoor temperature humidity levels using geothermal energy. maintained temperatures 10°C–20°C 30%–50%, with US$2120 construction cost rising maintenance expenses, offering significant savings as viable HVAC alternative despite high initial investment.
