Abstract
Egypt, as a developing country, suffers an energy crisis manifested by limited energy resources and increasing demand. This crisis is anticipated to worse in next few years due to the fast developments in major sectors of the country, including the building sector. The existing building stock in Egypt consumes more than 60% of the electrical energy. Improving the energy performance in buildings can be done by retrofitting the building envelope, using more efficient energy-using equipment such as lighting and air conditioners, using renewable energy sources, and altering the occupants’ behavior concerning energy usage. In this paper, a quick, easy-to-implement procedure is proposed for implementation in existing office buildings. The procedure combines both economic and environmental aspects of energy conservation methods and prioritize them, along with the solution economics, energy saving and environmental benefits. An office building in Alexandria, Egypt, is taken as a case study to illustrate the effectiveness of the procedure. The results are easily presented to the decision makers. The procedure can be applied to most non-residential buildings. A national action plan is required immediately to be implemented in Egypt seeking for energy conservation actions in the existing building sector, which can save energy, decrease fuel imports to operate power plants, decrease the need to build new power plants, decrease the associated carbon dioxide emissions and improve the overall economic situation of the country.
