ENERGY-EFFICIENCY IN AIR-CONDITIONED BUILDINGS: AN OVERVIEW

The Egyptian community in its path for rapid development is endeavouring to make all necessary and appropriate measures to enhance the efficiency of energy utilization and increase the beneficiation of the energy resources. Throughout the Nation, Energy resources are widely used and consumption rates are in general exceeding the International accepted values. The use and application of new and renewable energy sources can be harnessed to design, construct and operate a solar building of moderate size for desert applications. The paper demonstrates the importance of incorporating an energy performance directive as a Standard in our region such a goal will aid energy savings in large buildings and set regulations to energy efficient designs that are based on Standard calculation methods. The target is to develop standardised tools for the calculation of the energy performance of buildings, with defined system boundaries for the different building categories and different cooling/heating systems. Endeavour to prepare models for expressing requirements on indoor air quality, thermal comfort in winter and when appropriate in summer, visual comfort, etc is targeted with a common procedure for an “energy performance certificate”
