中文摘要:
      随着世界能源危机的出现以及环境污染越来越严重,人们越来越重视建筑节能,坚持走可持续发展道路,建立生态文明社会。屋顶作为建筑围护结构的重要组成部分,对建筑节能影响很大。屋顶处于气候变化最激烈的部位,是左右顶层空间的舒适度和空调耗能的关键,尤其是低层建筑或大空间建筑的屋顶,更应该重视屋顶节能。本文基于合肥市气候条件,运用ECOTECT软件对采用普通屋顶、一般坡屋顶和保温隔热屋顶这三种不同屋顶形式的建筑进行能耗模拟,将模拟结果进行对比分析可得:保温隔热屋顶的节能效果明显,一般坡屋顶的节能效果一般,对于屋顶节能,要优先选用保温隔热屋顶。若采用坡屋顶形式,应增设老虎窗通风,节能效果更佳。
英文摘要:
      With the emergence of the world energy crisis and environmental pollution getting increasingly serious, people pay more and more attention to energy conservation in building, stick to the road of sustainable development and establish ecological civilization. As an important part of building palisade structure, roof has great influence on building energy efficiency. On the roof , the climate change in fiercest and it serves as the key factor determining the space comfort and air-conditioning energy consumption of the top floor. People should pay more attention to energy saving of the roof, especially the roof of low-rise buildings and large space buildings. Basing on the climate conditions in Hefei, this paper uses the ECOTECT software to simulate the energy consumption of the buildings respectively with ordinary roof, general sloping roof and heat insulation roof. Through comparison between the simulation results, it can be found that energy saving effect of heat insulation is obvious and there is little energy saving effect of sloping roof. For roof energy saving,people should give priority to the heat insulation roof. If the slope roof form is adopted, people should add the tiger window on the roof.
