当前,我国已基本完成当初设定的居住建筑节能三步走的历史任务,接着居住建筑节能标准提升目标该如何设定,是摆在每一个节能管理和研究人员面前的问题.本研究提出以DeST-H软件模拟为基础获得建筑节能提升的技术方案,利用边际收益率作为经济评价指标优选建筑节能方案,计算出相应的建筑节能提升率,初步设置提升梯度.依据技术经济评价结果和当地的节能发展状况制定节能设计标准提升调查表,进行德尔菲问卷调查.利用算术平均值(M)和变异系数(V)对调查问卷结果进行指标评价,当2.5≤M≤3.5且V<0.2时,该项建筑节能设计标准的提升梯度和时间节点被选用,否则,重新设定提升梯度和时间节点进入下一轮问卷调查,直至满足要求.最后,利用该研究方法,提出了陕西省居住建筑节能设计标准的提升方案.
At present, China has basically completed the original set of residential building energy-saving three-step historical task. But how to set the gradient and the time node of design standard for energy efficiency of residential buildings, is the problem placed in front of every energy-saving management and researcher. The paper proposes a technical scheme to obtain the improvement of building energy efficiency based on DeST-H software simulation. The marginal rate of return is used as the economic evaluation index to optimize the optimal building energy saving scheme combination, for calculating the corresponding building energy saving rate, and setting the lifting gradient. Based on the results of technical and economic evaluation and the development of local energy-saving, the questionnaire of the improvement of design standard for energy efficiency of residential buildings is enhanced for Delphi survey. The average gradient(M)and the coefficient of variation(V)are used to evaluate the results of the questionnaire. When 2.5≤M≤3.5 and V<0.2, the lifting gradient and time node of design standard for energy efficiency of residential buildings are selected. Otherwise, the lifting gradient and time nodes are reset into the next round of the survey until the requirements are met. Finally, using the research method of this paper, the scheme of design standard for energy efficiency of residential buildings in Shaanxi province is put forward.
