Balcony and Jalousi Effectiveness Review to Promote Daylight in Interior for Tropical Country

City growth will eventually affect its people lifestyle. Higher buildings, which serve higher economic value, will need to be
supported with open area for social interaction. The three principal of sustainable design is not only to embrace the economi c
growth, but also to consider social interaction and ecology in it. Since the colonial era Balconies and jalousies are well known as
architectural elements that provide more space for interaction, economically possible to make use of, and provide shading for the
space underneath. This research will investigate how these elements efficiency will affect the introduction of daylight into interior
space to save energy. This quantitative research was conducted with IES -VE 2012 software with embedded suncast, Flucs-DL,
and Radiance software in it to calculate the depth of daylight penet ration and glare potential. The simulation was set in tropical
country (Singapore).
