北方地区被动式办公建筑能耗分析研究

Analysis of energy consumption of passive office buildings in North China

以寒冷地区某一具体被动式办公建筑为原型,应用e QUEST能耗计算软件分别按照工程实际和我国公共建筑节能设计标准建立模型,选取我国北方地区10个城市为研究对象,对比被动式办公建筑在北方地区相对于我国《公共建筑节能设计标准》设计的标准建筑的空调能耗情况。结果表明:按照德国被动式办公建筑参数设计的办公建筑夏季制冷能耗基本与常规节能建筑持平,而冬季采暖能耗有大幅度下降;就空调综合能耗来看,太原地区空调综合能耗节能潜力最大,空调综合能耗比常规节能建筑降低54.16%;哈尔滨地区最低,但也比常规节能建筑能耗减少了34.06%。

Based on an existent passive office building in cold areas,two different models were set up according to actual condition and domestic design standard by using the e QUEST software. Ten cities located in different provinces in North China were selected to compare the energy consumption of air conditioning. The results show that the passivhaus have almost the same energy consumption in summer with the normal buildings,but in winter,the heating energy consumption of the passivhaus has great decline. On the comprehensive energy consumption of air conditioning,Taiyuan has the largest energy saving potential. In Taiyuan and Harbin,the passivhaus＇ s air conditioning energy consumption is 54. 16% and 34. 06% less than the domestic normal buildings respectively. Passive office building has great potential for energy saving in northern China.
