    Comparative thermal performance of static sunshade and brick cavity wall for energy efficient building envelope in composite climate
    (Doiserbia, 2014) Gupta, Rajiv; Charde, Meghana
    Energy efficient building technologies can reduce energy consumption in buildings. In present paper effect of designed static sunshade, brick cavity wall with brick projections and their combined effect on indoor air temperature has been analyzed by constructing three test rooms each of habitable dimensions (3.0 m × 4.0 m × 3.0 m) and studying hourly temperatures on typical days for one month in summer and winter each. The three rooms have also been simulated using a software and the results have been compared with the experimental results. Designed static sunshade increased indoor air temperature in winter while proposed brick cavity wall with brick projections lowered it in summer. Combined effect of building elements lowered indoor air temperature in summer and increased it in winter as compared to outdoor air temperature. It is thus useful for energy conservation in buildings in composite climate.

    Design development and thermal performance evaluation of static sunshade and brick cavity wall: An experimental study
    (Elsiever, 2013-05) Gupta, Rajiv
    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 (3.0 m × 4.0 m × 3.0 m 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.
