Abstract: Toplighting in warm and humid climates have always been a problem for designers due to associated solar heat gain. This paper aims to analyse toplighting fenestration systems and the relationship between their heat gain and luminous performance of buildings in intertropical regions. Using simplified methods to evaluate solar heat and daylight admission the paper analyses three types of toplighting systems at the equator. It also examines the effect of shading devices and reflectance of external surfaces on the system luminous efficacy.
