Electric power is undoubtedly one of the main pillars of economic and social development in modern times worldwide. In Palestine, as in the rest of the world, electric power has great importance; in some cases, it surpasses that of other nations because Palestine is a developing country under occupation aspiring to achieve an economic and social development free from the control of the Israeli occupation. The main objective of this thesis is to establish a pace toward the efficient use of energy and energy management in large or medium buildings through conducting several procedures in some different buildings where lighting, air-conditioning, oxygen generation units, power factor or other service levels can be reduced without detriment to comfort or health care. In this thesis, we will also define the concept and importance of rationalization of electric energy, and we will determine the responsibilities towards the rationalization of electric energy, the efforts of the electricity sector in the rationalization of electrical energy and procedures Thermal insulation is one of the most important methods of energy conservation in buildings, which contributes to the preservation of the internal heat of buildings for long periods. In this thesis we will present an economic feasibility of thermal insulation, just to apply the economical strategies to determine the best heating and cooling isolation system (using polyethylene isolation materials) from the following alternatives: 1- Isolate all of floors and walls. 2-Isolate the walls. 3- Do nothing (Not use any isolation system) we have chosen a government building where the building consists of five floors, each has a 1950 m2, according to information obtained from the management of the building, the monthly bill for heating and lighting is 4,000 JD. On other hand, 57% of the bill is for heating and cooling system and 43% is for lighting. The economical engineering strategy that used in this study is life cycle cost analysis life (LCCA). The results show that using the polyethylene isolation materials to isolate walls will decrease the monthly bill to 55% and the IRR will be 16%. On other hand, isolated all walls and floors will decrease the monthly bill to 40% but the IRR will be 13%. The last alternative which is not using isolation were not accepted. Finally, the recommendation is to use alternative two; to save at least 121000 Jordan Dinars over 20 years, while 150000 Jordan Dinars will save if the building isolated all walls and floors over 20 years.
