تطبیق إستخدام الطاقة المتجددة بالمبانی الإداریة القائمة کأحد جوانب توفیر الطاقة

Abstract

Egypt's consumption of non-renewable energy sources led to a shortage of its natural reserves of oil, natural gas and coal, and the depletion of available resources without taking into account the right of future generations. Also, energy production from these sources causes environmental pollution and as a result, the World Health Organization has determined that the proportion of pollution in Egypt exceeds Three times the global rates of environmental pollution, and therefore we should go to the use of renewable energy sources. The old existing office buildings were chosen because they represent a large percentage compared to new construction, and suffer from energy consumption during work days ,so this research paper aims to identify weakness points in the development of old office buildings in Egypt, it's important to develop the old buildings because of their economic and environmental benefits, they are less expensive than new buildings in terms of economic cost and energy consumption and on the other hand it helps to extend the building life. This study follows the inductive methodology by studying the strategies of some countries to improve and develop energy efficiency in the old office buildings through the renewable energy's application, Andfollow the analytical methodology by analysing global and local office buildings that have been developed andimprove its energy efficiency.
