严寒地区居住建筑节能改造优化模型探究
Study on the optimization model of energy efficiency renovation of residential buildings in severe cold areas
摘要
Abstract
In order to promote the building energy saving process and adopt more economical energy-saving transformation strategy to meet the increasing demand for building energy efficiency in cold areas, two kinds of energy saving models are established for a nine-storey residential building with two strategies of improving the thermal insulation performance of the building envelope and changing to install the bidirectional ventilation windows(BVW) in Harbin.Energy consumption software is used to simulate and analyze the energy efficiency and economy of the two models.Compared to the use of the BVW before and after the energy consumption changes, the energy saving rate of the basic model is improved by about 15%, and the saved cost per square meter is 1.87 RMB annually.The energy saving rate of the first energy saving model is increased by about 13%, and the average saved cost per square meter is 1.42 RMB annually.Compared with the way of improving the insulation performance of the envelope to achieve energy saving effect, the use of the BVW can improve air quality and get better energy saving effect.The study result has some reference for关键词
