Abstract:
Most of modern high rise office buildings in tropical humid region are experiencing new trend in their physical facade design. They have large glazing area in order to make the image of modern an corollary the need for a light construction. The objective of this study was to assess the daylighting performance. i.e. daylight intensity level and their uniformity in the open plan glass-facade offices due to the building’s glass type and its core position which affects the window arrangement. Three case studies were conducted at typical Indonesian office buildings with different core positions which determine the possible availability of daylighting sources, the type of glazing and the interior shading they are used. Overall the findings show that the bilateral side daylighting system contributes to more even and gentle distribution compared to that of multilateral side light window. Furthermore, the application of both tinted and refrective type of glazing contribute to significantly high illuminance level in the building perimeter and considerably low illuminance level in the core zone. Hence, this also affects the daylight uniformity performance in the space. Among building physical variables studied, buildings with reflective glass facade and that with single side core (multilateral window positions) provide more contribution to these phenomenon compared to those with tinted glazing and other two window positions.
