|Title||Effect of Wall Thermal Properties on the Energy Consumption of Buildings in the Gaza Strip|
Improving the energy efficiency of buildings is proposed worldwide to be considered as part of the overall solution to the problems associated with the use of conventional energy in buildings. The tendency of producing more energy efficient buildings has, additionally, special importance in the Gaza strip, considering the severe energy deficit that has been suffering from in recent years. It is evident that buildings sector consumes the main bulk of electricity supplied to the Gaza strip. Accordingly, this research aims to find out the potential of reducing the energy consumption of buildings through the proper selection of wall construction materials. For this purpose, the research examines the effect of the thermal properties of various wall combinations on the annual required energy for heating and cooling. Computer programs were used to simulate the various cases and to calculate the amount of energy required. This includes, a simple calculator developed by the author based on the steady state method of Cooling Load Temperature Difference (CLTD). In addition, Ecotect program was used also to carry out the simulation and validate the results. The outcome of the research reveals clearly that the thermal properties of wall building materials have a significant effect on the amount of energy consumed by buildings. It was concluded that applying the U-value of walls (1.8 W/m2. k) recommended by the local Energy Code results in a reduction of 22% in the required heating and cooling energy of residential buildings in the Gaza strip.
