• Summary An analysis of the performance of a fixed‐plate air‐to‐air energy recovery system on its efficiency and recovered energy for potential building applications in the hot and humid environment was performed. Investigations were executed under controlled laboratory conditions in an energy testing chamber. Tests were carried out with varying operating parameters in terms of airflow rates that ranged from 1.0 to 3.0 m/s, intake air temperature of 28°C, 31°C, 35°C, 40°C and intake relative humidity of 70%, 75% and 80%. The performance was analysed by adopting the calculation methods of the ASHRAE Standard. This study showed that increased airflow rate decreased efficiency. The increase of airflow rate raised the recovered energy of the system. The study indicated that increasing values of intake air temperature (Tin) resulted in the increase of efficiency and recovered energy. A decrease in the efficiency of the system was observed, notably when the intake relative humidity (RHin) increased. World energy consumption and global warming are rising rapidly as a result of the increasing demand for energy with various sectors, including the building sector. Air‐to‐air energy recovery systems are heightened in many buildings of various climatic conditions towards the reduction of energy load, CO2 emissions, and improved indoor air quality.
