Abstract

One comfort issue that considered to be the most important is thermal comfort. Air temperature is the most influential factor, and it is related to solar radiation and building's glazing. Besides thermal comfort, glazing is also needed to provide daylighting. Therefore, due to its relation to thermal comfort and daylighting, the glazing materials selection is crucial. Hence, by focusing on atrium in hot and humid climate, this study is aimed to examine a sufficient material with good thermal and daylighting performance. The results show that argon filled glazing is the most suitable material for atrium glazing in hot and humid climate. Argon filled glass has lowest U-value and total solar transmission than any other glazing materials simulated, but its light transmission is not too low so the daylight delivered still adequate to the standard. Accordingly, U-value, solar heat gain coefficient, and light transmission coefficient are concluded as the determinant factor in selecting glazing material.
