| Thermal confort accompanied with low energy in architecture is a major target of building researchers and designers worldwide. Obviously, any portion of energy that can be saved in this respect means protection for environment and maintenance of its resources and may be able to be directed to any other activities, if any. Building energy consumption can be reduced through various systems such as air conditioning (A\C is a major building energy consumer), lighting, equipment, etc. In regions where energy is limited or scarce, air conditioning would have to be replaced by natural ventilation for the removal of the building heat load for thermal comfort. Also, energy conservation issues are being more important in hot arid regions, especially because building are consuming more than 60% of electric energy generated and about 65% of this energy is consumed for cooling. There is a set of complex factors, which determines energy needs in building, such as solar radiation, type of A/C systems, building operation, and thermal characteristics of the building envelope …etc. The parameters, which have effects on the thermal performance of walls and roofs, are the color, general construction, insulation and ventilation. In the present decade the aim is to discuss the meaning of thermal comfort and advantage of energy efficient building materials design or selection. There are several ways to reduce the energy consumed in the human comfort process, but what is the most energy efficient or more energy saving of these ways. One of these is the insulation, which can be used for insulating walls and roofs, which are subjected to a large amount of the solar heat gain. The insulation of walls (especially west walls) and roofs is intended to maximize resident’s thermal comfort and minimize energy consumption in housing. The present study presents the effect of west wall insulation on the indoor thermal performance in order to select the suitable insulation which gives maximum thermal comfort , minimum cost and maximum energy saving. This work was done using actual field temperature measurements on actual location. The results provide suggestions to improve the building construction and indicate the importance of using the insulation materials in the wall construction in order to achieve thermal comfort characteristics for the occupants and also to reduce the consumed energy. | ||||
