摘要
据统计,乌鲁木齐市既有非节能居住建筑数量十分庞大,若全部实施节能改造,改造费用负担很大。此外,由于部分建筑改造价值较小,改造后的社会、经济效益亦不高。因此,应对改造对象进行界定。基于以上考虑,通过既有非节能居住建筑改造价值影响因素分析,采用层次分析法量化了各影响因素的权值向量,构建了既有居住建筑节能改造标准的AHP评估模型。在此基础上,提出综合评估指标(CAI)来判定既有居住建筑的节能改造价值。实际应用表明:根据所得到的最终评估得分能够综合评价既有居住建筑是否具有改造价值,该方法具有一定的应用价值。
According to the statistical result,there are a large number of the existing residential buildings which are non-energy efficient in Urumqi.Supposing that all of the buildings are retrofitted,investment used to reconstruct these buildings is too much.Furthermore,the economic and social benefit for the part of the retrofitted buildings is not enough because of lack of energy efficiency reconstructing value.In a word,it is of importance to select the retrofit objects.Therefore,on the basis of analyzing the facts that influence energy efficiency reconstructing value in existing residential buildings in Urumqi,the main functions of the AHP model which is used to construct standard for energy efficiency retrofit of existing residential buildings and its application are briefly described.Comprehensive assessment index（CAI） is proposed.Result shows that the final values can be used to evaluate whether existing non-energy-saving residential building should be reconstructed or not.The method is valuable.
