The energy consumption and actual operation effect of two projects obtained the Three-star operating label for green buildings are compared.The energy consumption levels of both projects are excellent.Compared with the guidance value level in the"Civil Building Energy Consumption Standard"(GB/T 51161-2016),the non heating energy consumption reduction rates of Project A and Project B have reached 20%and 9%respectively,as well as the heating energy consumption reduction rates have reached 21%and 5%.Meanwhile,the actual operation of the project is analyzed,the excellent energy-saving operation and maintenance of Project A is summarized,and the reasons for the problems existing in the actual operation of Project B are pointed out and the preliminary solutions are proposed.Some suggestions on the energy-saving work in green building operation and maintenance are expounded from four aspects,including establishment of a refined energy management system,organization of a professional operation and management team,strengthening on the comprehensive debugging of electromechanical system and energy-saving diagnosis of electromechanical system,in order to solve the common issues in the actual operation.
