When considering energy efficiency optimization in construction project management, one of the best evaluation criteria is the building life cycle energy analysis; that, includes the embodied energy in the building and the operating energy during the life of the building. The present study consists of two steps; 1- Library, statistical and descriptive study (selection of suitable options for life cycle energy optimization of buildings) and 2- Case study (analysis of embodied energy of construction and operation of the building through modeling in energy simulator software design Builder). The results of the life cycle energy analysis of a real educational building in Tehran with a lifespan of 50 years, taking into account ground heating, in the three states of this building; basic available, optimal and optimal with a green roof showed; That, the amount of life cycle energy of the studied buildings is 51.86, 44.82 and 43.89 GJ / m2, respectively. Also, the annual energy consumption during the operation period of the basic educational building in Tehran was estimated to be equal to 0.80 GJ / m2, although this amount was in the range of values provided in global research, but the amount of energy consumption during the operation period of this building Compared to global cultivars, it is a large and significant amount. The overall results indicated; that, The energy consumption during the life of the studied building in the optimal and optimal with a green roof state was less about 24,220 GJ (equivalent to 3958 barrels of crude oil) and 27,420 GJ (equivalent to 4480 barrels of crude oil), respectively, compared to the existing base state.
