Description

technical field [0001] The invention relates to the field of electrical engineering, in particular to a commercial building energy efficiency optimization method based on a hybrid genetic simulated annealing algorithm. Background technique [0002] With the continuous development of society, energy issues have increasingly become one of the major issues of common concern in the world. Energy efficiency optimization has become urgent, and energy development and energy conservation have become the basic energy policies of our country. According to relevant statistics, the energy consumption per unit area of ​​large public buildings in my country can reach 70-150kW·h / m per year 2 , while the energy consumption of large commercial buildings such as shopping malls and hotels accounts for more than 60% of building energy consumption. According to the comprehensive analysis of power consumption, the central air-conditioning system, lighting system and elevator system are three imp...

Problems solved by technology

In order to improve energy efficiency and reduce energy consumption, Lombard L.P proposed a method to set up different energy efficiency evaluation standards for central air-conditioning systems according to different climate conditions and building types; D Cooper and A.B.Kulkarni used electric energy meters to measure the total daily energy consumption of elevators in their research , as the evaluation index of energy consumption; the United Kingdom, the United States, Canada, Japan and other developed countries have established energy-saving evaluation systems in line with their own national characteristics. All countries stipulate that in the process of implementing energy-saving technologies for commercial buildings, they must rely on the established norms and guidelines, which require a qualitative and quantitative real assessment of the effect of electrical energy conservation and electrical energy conservation technology. In contrast, my country has not established a complete commercial building electrical energy conservation technology evaluation system
