Evaluation of a New Static Sunshade for Composite Climate using Experimentation

Abstract

Windows, which play a vital role for direct solar entry inside the passive solar buildings, should be properly shaded for the comfort conditioning. The present paper aims at the new geometrical design of a static sunshade by calculating solar angles for the two specific dates of varying seasons over a place. Five small-scale experimental models of varying aspect ratios and sunshades have been analyzed over a complete year. Depending upon the solar intersection over south facade wall, sunlit area or shaded area has been correlated with temperature inside the models and made criteria to decide the effectiveness of the proposed sunshade.
