SURVEY OF CHANGE IN HUMIDITY, TEMPERATURE AND ILLUMINANCE BY USING DIFFERENT MATERIALS FOR ROOF CONSTRUCTION

A roof is uppermost part of building or shelter which plays a predominant role in protecting inner elements and living things inside structure, this protects against weather, rain, snow, heat, wind and sunlight. The protection properties of roof vary by composites with which the roof is made. In this paper analysis of temperature, humidity and illuminance properties variation due to different types of roofs, the survey made on different roofs such as R.C.C, Asbestos sheets, planks and shack type of roofs for 24 hours are compared to reading that are obtained by open place reading without any roof. This survey clearly represented that readings gradually increases when sun is at his highest point and reduces to zero in the absence of sun. This survey also revealed that using asbestos sheet roof will increases humidity of roof eventually and by using shank roof reduces the temperature, humidity, and lux values passing in to building. Hence this says that although shank roof are less strength roof compared to all roofs these can be used in arid region to reduce interior temperature and humidity, although asbestos sheets are thin layered these can be used in places where humidity and temperature is required compared to temperature and humidity outside the building
