This study aims primarily to provide a suitable internal environment for Palestinian houses by providing better properties and specifications for the building materials used in these buildings, which will lead to reduce the rate of heat transfer through casing elements of the houses and thus to rationalize the energy consumption needed for heating and cooling them. In order to achieve this goal the comparative, descriptive and analytical methodology has been adopted in this study. A comparative study of the heat transfer values has been done in a sample of both contemporary residential as well as traditional houses in Hebron city. The study has been allocated on the exterior walls of these buildings as they are one of the most important casing elements, concerning their thickness, location and the value of overall heat transition. Moreover, the exterior elevations have been studied concerning their orientation openings’ proportions and glass properties used in them. The study concluded that to get to the thermal satisfaction in residential buildings it is essential to obtain particular conditions and specifications for building materials and architectural design used in exterior walls, in order to overcome the characteristics of the surrounding environment. Finally an ideal section for external walls was proposed which will lead to the rationalization of air conditioning energy consumption.
