Design Modification for Existing Buildings in Palestine to Adapt to its Environment in a Changing Climate

This study aimed to identify the modified design of residential buildings in Palestine to adapt to their environment due to climate change, and to achieve the objectives of the study, reliability and validity of the study instrument were tested, also, after data collection process, data were coded and entered and processed statistically. The study population consisted of all existing residential buildings in the cities of Qalqilia and Nablus in 2015. the study sample consisted of (100) buildings in the cities of Qalqilia and Nablus, the sample building was chosen purposely. Moreover, the study relied on computer simulations to develop a model that represents a building scattered in Palestine in the cities of Qalqilia and Nablus to compare the effect of directing the building, thermal insulation, shading and crowding with the surrounding buildings on the thermal performance of the building and thermal satisfaction. the study concluded that the best orientation of the building to the south with a shading elements considered an appropriate thermal insulation has led to a reduction of energy consumption in the heating and air-conditioning in both cities by 45%. Furthermore, the increase in building density leads to lower thermal satisfaction of the population and increase the energy consumption of heating and air conditioning, especially in hot and humid areas, this requires the need to expand Street View to increase air movement, especially in those areas to provide better climate environment and reduce dependence on means of industrial air conditioning thus energy conservation to reduce the emission of environmentally harmful gases.
