建筑总能耗主要受建筑空调系统能耗变化的影响,空调系统能耗又与建筑自身构造和空调系统的运行方式有关,如建筑朝向、窗户、屋顶、遮阳、窗墙比、通风换气方式、空调系统设备运行管理方式等。为了解夏热冬冷地区公共建筑能耗现状和特点,并为建筑节能设计和既有建筑节能改造提供参考和指导性建议,本文以武汉市房地产交易大厦为例,首先采用能耗模拟与实测调查相结合的方法,对大楼空调系统的运行和管理提出了节能改造建议,而后采用正交试验法,研究得出了各建筑能耗影响因素对建筑负荷影响的主次关系,从而对各影响因子的节能潜力进行探讨。
The total building energy consumption is mainly affected by the change of energy consumption of the building air-conditioning system. The energy consumption of the air-conditioning system is related to the operation mode of the building itself and the air-conditioning system such as building orientation, windows, roof, shade, window wall ratio, ventilation mode , Air-conditioning system equipment operation management. In order to understand the current situation and characteristics of energy consumption of public buildings in hot summer and cold winter area and to provide reference and guidance for energy-saving design of buildings and renovation of existing buildings, this paper takes real estate transaction building in Wuhan as an example, Investigation and combination of methods of building air-conditioning system for the operation and management of energy-saving proposals put forward, and then the use of orthogonal test method, the study obtained the impact of various building energy consumption on the impact of building load on the primary and secondary relationships, and thus the impact The energy saving potential of factor is discussed.
