摘要
自然通风技术是建筑可持续发展的一个重要发展方向,而自然通风潜力是评价自然通风的重要指标。自然通风潜力应综合考虑热压、风压、空气质量、环境噪声对自然通风应用效果的影响。本文采用Qualiflex矩阵对我国八大城市的自然通风潜力进行了多标准评估分析。其中引入自然压差帕时数来表征热压、风压潜力影响值,建立了自然通风潜力与压差帕时数、空气质量、环境噪声之间的函数模型,并通过计算分析,得到八大城市的自然通风潜力最优排列及综合比较结果。
Natural ventilation technology is an important direction for the strategy of building sustainable development, and natural ventilation potential is an important assessment index for natural ventilation. To evaluate the natural ventilation potential, the comprehensive influence of local wind, stack effect, pollution and noise should be primarily considered. In this paper, Qualiflex matrix is applied to evaluate the natural ventilation potential of eight cities of China. Pressure Differences Pascal Hours （PDPH） for natural ventilation is introduced in the paper to account for the influence of local wind and stack effect. Base on the fact, a mathematical model which describes the relationship between the natural ventilation potential and PDPH, air mass ＆ ambient noises is established. According calculation and analysis, the natural ventilation potentials of the eight cities in China can be ranked, so the comprehensive compare of natural ventilation of eight cities can be got.
