Designing Equator-Facing Window for Direct Solar Gains Optimisation in Buildings

Abstract

As solar gains play a vital role in influencing thermal environment in determine the shading device size and corresponding RBH while apparent sun-paths model described in Szokolay (2007) for this analysis. facing window would aid in improving thermal performance of buildings equator-facing window height on horizontal shading device size and the buildings, direct solar gains is the most influential of the three modes of indicating that optimising direct solar gains does not rely on largest window which requires only horizontal shading device for optimisation. In varying the window height, calculated solar altitude was used to rate of change of radiation beam height (RBH). This study adopted the increases the shading device size as well as corresponding RBH. However, transmission. So, optimising direct solar penetration through equator gains in buildings, and a useful means for architects to design equator However, it provides a basis for further research in modelling direct solar examining its rate of change. Results show that increase in window height the rate of increase of RBH diminishes with increase in window height window height. This study focuses on vertical aspect of the equator-facing during winter. This study seeks to investigate the effects of varying facing windows.
