Energy efficiency of building, promotes strongly the integration of passive strategies, in order to achieve a thermal comfort especially in summer conditions by reducing or preventing the use of air conditioning systems. In this work, building energy performance has been evaluated using an earth-air heat exchanger (EAHE) during summer period. Energy requirements was analysis by the means of dynamic simulation tools called (TRNSYS) for hot and arid climate in the southern Algeria. This analysis was conducted function of different (such as soil typology, tube material, tube length and depth, ventilation airflow rates). Results show that earth-air heat exchanger has the highest efficiency for arid climates. Furthermore, the possibility of coupling of this technology with other passive strategies (nocturne ventilation and thermal mass) has been also examined. High efficiency was observed.
