Abstract

In this study, heat gain from solar energy through Trombe wall was investigated in Turkey. The wall materials, reinforced concrete, brick and autoclaved aerated concrete, were taken into consideration with various surface colours. The passive heating potential of Trombe wall was estimated by using unutilizability method which is used in the designs of passive systems for heat gain. The results indicated that the annual heat gain from solar energy through Trombe walls was found out to be between 26.9 to 9.7% for concrete, 20.5 to 7.1% for brick and 13.0 to 4.3% for aerated concrete in different surface colours.

Key words: Solar energy, Trombe wall, energy consumption, energy gain.
