Five identical test structures have been fabricated for studying passive techniques for better comfort conditioning in arid areas. As 50% of the heat load in the building is from the roof, therefore, it has been treated with different passive techniques, viz. painting of roof by white paint, thermal insulation underneath roof, shallow pond with movable insulation and soaked gunny bags with water. It has been found that the fall in roof and ambient temperatures inside the test structures were in increasing order for roofs treated with thermal insulation, painted with white paint, shallow pond with movable thermal insulation and evaporative cooling.
