Design development and thermal performance evaluation of static sunshade and brick cavity wall: An experimental study

Abstract

Energy efficient building technologies reduce energy requirements in buildings. It is possible to maximize solar heat gain in winter, avoid overheating in summer by proper design of building elements and bring indoor air temperature near comfort zone (18–27°C) to optimize energy needs. In present paper effect of proposed static sunshade, brick cavity wall with brick projections and their combined effect on indoor air temperature has been analyzed by constructing three rooms each of habitable dimensions (3.0m×4.0m×3.0m high) and studying average hourly temperatures for three months in summer and winter each. Performance of proposed static sunshade has been found to be better than horizontal static sunshade in winter while that of proposed brick cavity wall with brick projections is better than a solid brick wall in summer. Combined effect of proposed static sunshade and brick cavity wall with brick projections has been effective in keeping indoor air temperature less in summer mornings, more in winter nights and hence useful for energy conservation in buildings as per seasonal needs.
