In this study, energy conservation potential of appropriate passive cooling and basic heat avoidance strategies were investigated for hot and humid climates. Within this framework, thermal behavior of a case study building that is situated in Cyprus was assessed by collecting temperature and relative humidity data from various rooms of the building during certain days in August. Then, by using feasible simulation strategies of the software tool Summer-Building, the effectiveness of passive cooling measures in reducing energy consumption were examined, for summer months. In this context, the case study building was re-evaluated by applying natural ventilation, night ventilation and ground cooling strategies as well as solar control and shading devices as overhangs and side fins. Consequently, based on the results of the evaluation model, it was found that the proposed passive cooling strategies and basic heat avoidance concepts could provide more than 50 % energy conservation, relative to the completely air conditioned reference building, between 1-15 August 2007.
