【摘要】 新建居住建筑的节能效果受多种因素共同影响,如何对其节能效果进行客观、准确、合理地评价,一直是建筑节能领域研究的重点内容。基于可拓理论,提出了一种将定性与定量相结合的新建居住建筑节能效果评价方法——可拓方法,并详细介绍了该评价方法的步骤。以实际工程为例,综合考虑多种影响因素,建立了居住建筑节能效果综合评价指标及其量值标准,采用简单关联函数计算各评价指标的权重,有效避免了主观因素的影响。在此基础上,引入可拓学,构建了新建居住建筑节能效果可拓评价的物元模型,通过关联度和等级度计算,客观全面地给出了居住建筑节能效果综合评价结果。实例结果表明,该方法能够有效地保证节能效果评价的质量和效率,实际操作简便,具有可行性。更多还原

【Abstract】 The energy-saving effect of a new residential building is controlled by various factors.How to evaluate the energy-saving effect objectively is an important research issue.Based on the extension theory,an extension method which combines qualitative and quantitative evaluations of the energy-saving effect for residential buildings is proposed.Taking a real project as an example,various factors are comprehensively considered,and the evaluation indicators and standards of the energy-saving effect for residential buildings are established.The weight of a factor is determined by a simple correlation function,to avoid subjective speculations in practices.On this basis,the extension theory is adopted.The matter element model for the evaluation of the energy-saving effect for residential buildings is constructed.The correlation and the grade are accurately calculated,to objectively and comprehensively evaluate the residential building’s energy-saving effect.Results show that the proposed approach is effective and efficient and the extension method can be used to estimate the energy-saving effect of new residential buildings.更多还原
