利用MATLAB建立BP神经网络,将影响建筑能耗的18个因素作为网络的输入,进行学习训练,最后通过测试样本点数据预测建筑能耗,与D eST-h模拟计算得到的结果比较,发现相对误差在3.5%以内,并通过实例验证了该网络模型的准确性。该方法使建筑人员在设计阶段就能快速且准确地获得设计建筑的能耗。 相似文献

随着我国城市化进程的加快以及随之出现的环境恶化、能源短缺等问题,建筑能耗越来越受到人们的关注。建筑能耗已逐渐增长至与工业能耗、交通能耗并列,成为我国能源消耗的三大"耗能大户"。因此,从建筑方案构思阶段就应该对建筑进行节能设计,以最小的成本得到最大的回报。以西安市某小区多层住宅楼为模型,利用能耗模拟软件分别对外墙、屋顶、窗户、建筑朝向及综合节能设计进行能耗模拟,对它们各自的节能效果进行对比分析,从而为建筑师进行建筑节能设计提供参考依据。 相似文献

医院建筑用能复杂,对舒适度要求高,导致能耗居高不下。在国家大力倡导合理用能的情况下,北京市医院管理局组织各相关专业对北京市市属几家医院进行节能改造。通过对北京世纪坛医院进行实地调研,从建筑师的视角出发辅助以相关能效计量结果,得出该医院建筑能源消耗的不合理之处。并对其节能潜力进行分析,提出了针对建筑物本身的节能改造措施。同时使用建筑能耗模拟软件Designbuilder对其改造后的建筑进行能耗计算,对比改造前的能耗,进一步证实改造措施的可行性,为医院建筑相关的改造和新建工作提供参考。 相似文献

Interest in ecological design issues has increased enormously over the past few decades and ecological problems are perceived to be on the increase. This paper seeks to investigate the relative importance of the design eco-drivers contributing to ecological building design (EBD) success in the UK. A large number of eco-drivers have been extracted from literature and current design practices. To compare views from architects, data were collected from a statistically significant number of practising architects in the area of sustainable design. The data collected represent the views and ambitions of surveyed architects and not necessarily their current design practices. Ranking techniques are utilised to identify the connotation of eco-design indicators. Based on this analysis, the most important eco-design drivers are extracted. From the results of the overall ranking 'energy, efficiency, energy consumption, energy-eco-efficiency and environmentally adapted technology', eco-drivers are ranked as the most important factors amongst others. This indicates that the surveyed architects strongly perceive ecological design as being driven by energy aspects of building assets. This suggests that these findings are more sensitive to respondents' perception rather than to actual design practices. The selected eco-indicators could be used to assist designers in carrying out ecological design contextual synthesis as well as developing ecological design strategies. 相似文献

The application of bioclimatic principles is a critical factor in reducing energy consumption and CO2 emissions of the building sector. This paper develops a regression model of energy efficiency as a function of environmental conditions, building characteristics and passive solar technologies. A sample of 77 bioclimatic buildings (including 45 houses) was collected, covering Greece, other Mediterranean areas and the rest of Europe. Average energy efficiency varied from 19.6 to 100% with an average of about 68%. Environmental conditions included latitude, altitude, ambient temperature, degree days and sun hours; building characteristics consisted in building area and volume. Passive solar technologies included (among others) solar water heaters, shading, natural ventilation, greenhouses and thermal storage walls. Degree days and a dummy variable indicating location in the Mediterranean area were the strongest predictors of energy efficiency while taller and leaner buildings tended to be more energy efficient. Surprisingly, many passive technologies did not appear to make a difference on energy efficiency while thermal storage walls in fact seemed to decrease energy efficiency. The model developed may be of use to architects, engineers and policy makers. Suggestions for further research include obtaining more building information, investigating the effect of passive solar technologies and gathering information on the usage of building. 相似文献
