Abstract

Skylights have been among the important devices in architecture for providing sufficient daylight in an interior space. The design of a skylight, in terms of shape, orientation, and glazing specification has a great visual and thermal impact on any internal space, and thus on the choice for its optimum design. This study evaluates the daylight factor, glare and cooling loads for different designs of skylight and compares them with one another to select the best design among them. In addition to the base skylight-free case, twelve cases, categorized into three groups, were analyzed and compared. The groups, named A, B, and C, have sets of fixed parameters that differ from one group to another. The cases in Group A showed a sharp increment in cooling loads, which became significantly higher than the other two groups had, although the lighting levels were not necessarily so. Groups B and C showed varying increments in lighting levels, while the cooling loads were relatively close. Case B-4 was considered the best among the twelve studied cases.
