This paper presents the thermal performance of a roof as a solar collector/storage system which is important for the thermal design of buildings. The system consists of a mass of concrete or concrete insulation, one face of which is blackened/glazed and exposed to solar radiation and ambient...

In this paper the thermal performance of an air space in an inclined roof and the optimum number of air spaces are discussed. One face of the roof is exposed to solar radiation and ambient air and the other is in contact with room air at a constant temperature. It is found that, for the desired...

In this paper, the effect of placing a reflecting sheet in an air gap on the thermal performance of single hollow, double hollow and insulated hollow walls and roofs is studied. One face of the wall or roof is exposed to solar radiation and ambient air and the other is in contact with room air...

This paper describes an analysis of the reduction of the heat flux coming into a room through a roof with an open water pond. A periodic analysis of the system, based on the linearisation of Dunkle's6 expressions for convective, radiative and evaporative losses, is presented. Numerical...
