Evaluation of Electricity Consumption of a Residential Flat in Egypt

Energy saving is one of the most important demands in our world .The aim of this paper is to evaluate the annual electrical energy consumption of a residential flat in EGYPT and how to reduce it. This evaluation includes the compatibility of a flat for the Egyptian code requirements of residential buildings. This flat is of a total area of 160 m2 with one facade opening. A software package Visual-Doe 4.0 was used for this analysis. Three different climatic regions were used for this analysis: Cairo, Alexandria and Aswan cities with different weather conditions (due to their geographical location on latitude 30.1, 31.2 and 24 respectively). The results give the minimum requirements of walls insulation (2.5cm) for different orientation and different climatic location. Also an average maximum reduction of about 17.11 % of the total electrical energy consumption with insulation 5cm compared to the actual consumption is fulfilled
