Comparative Advantage of Louver Shading Device on Window for Residential Building Located at Raipur

摘要

Buildings require large amount of energy for cooling as well as heating. Solar heat gains through window contribute half of the cooling load for residential and non-residential buildings. In this work, a comparative study among the effect of louver shading and fixed overhung has been carried out for Raipur (21.2514° N, 81.6296° E) city. The objective of the study is to compare the heat gain through window, for without shading, fixed overhung shading and louver shading for particular day and throughout a year. The results show that the integration of louver shading device in the building reduces indoor heat gain in summer and may lead to significant energy savings. The possible energy saving if louver shading used in the residential building is 740.25 kWh for one year.
