OPTIMIZING DAYLIGHT IN AN OFFICE BUILDING FOR MODERATE CLIMATE OF PUNE

Daylight has been an immortal source of light. But currently, due to lack of resources this source is supplemented by artificial light. The illumination levels are a big contributing factor towards indoor comfort. To optimize daylight in a building, it must be oriented according to solar design. Shading, orientation, window openings are the major contributors in energy efficient building. This paper deals with the quantitative analysis of daylight through different types of openings and fenestrations used in an office building. The study is for the moderate climate of Pune. The paper also helps to understand passive design strategies like building orientation, building shape, building envelope, shading devices, etc. The analysis is done by generating simulations on software for different WWR (Window Wall Ratio), window sizes and type of glass. The strategies and guidelines for optimizing daylight in an office building are given based on the findings and results generated. Finally which type of office building design and fenestration is best suitable and can give daylight optimization without glare for a given climate is concluded
