Therefore, energy management system implemented according to international standard ISO 50001:2011 and all energy parameters in building measured through performing energy auditing. Then, while using energy auditing results, and measurement of energy consumption carriers as per bills and also distributing questionnaire and also interview with experts in order to Verification of energy auditing results, all effective factors in optimization of energy consumption are recognized. In the next stage, through modeling while using modern methods in data analysis, effective main factors in municipality buildings are identified. On the other side, influence portion and amount of each energy consumption elements in percent are recognized while using obtained results from energy auditing and measurement of all energy consuming parameters. As a Result, uncontrolled wall indexes, wall thickness, roof layer, window and net wall thickness as effective main variables in optimization of energy consumption in two parts of heating and cooling energies in buildings of municipality district 7 of Tehran city are recognized.
