摘要
目前建筑能耗大约占我国社会总能耗的27.4%,其中公共建筑每年耗电量约占全国城镇耗电总量的22%,因此公共建筑具有巨大的节能潜力。同时,随着我国不同地区的气候差异以及公共建筑节能策略的不同,公共建筑能耗指标存在显著的地域差异,即使是同一气候区不同城市能耗指标也存在差异,由此造成对公共建筑能耗指标现状和规律在认识上的不全面,从而使得公共建筑节能改造和管理的重点不容易抓准。为此,通过对上海、长沙、成都地区的多栋办公建筑用电能耗数据进行调研与统计,并基于指标体系以及夏热冬冷地区气候特点对办公建筑年度总电耗情况、逐月电耗情况、电耗拆分情况进行了分析,得到了该气候区办公建筑的电耗水平与特征。基于此,从建筑能耗管理、能耗设备、人员行为三个方面提出了办公建筑的节能策略建议,为该气候区办公类建筑的节能改造和管理提供了指导和数据支撑。
At present,building energy consumption accounts for about 27.4% of the total energy consumption in China,and the annual electricity consumption of public buildings accounts for about 22% of the total electricity consumption in China’s cities and towns.Therefore,public buildings have great energy saving potential.At the same time,with the climate difference in different regions of China and the difference of energy saving strategies of public buildings,there are significant regional differences in energy consumption indicators of public buildings,even in the same climate zone,there are differences in energy consumption indicators of different cities,which leads to the incomplete understanding of the current situation and law of energy consumption indicators of public buildings.As a result,it is not easy to grasp the focus of energy saving transformation and management of public buildings.For this reason,this article through to Shanghai,changsha,chengdu area of many office building energy consumption data of investigation and statistics,and based on the index system and the hot summer and cold winter region climate characteristic of the total power consumption of the office building situation,the power consumption situation,this article analyzes the power split from month to month,got the climate area power consumption level and characteristics of the office building.Based on this,this paper puts forward suggestions on energy saving strategies for office buildings from three aspects of building energy consumption management,energy consumption equipment and personnel behavior,providing guidance and data support for energy saving transformation and management of office buildings in this climate zone.
