摘 要 建筑室内新风量指标的合理确定是协调建筑节能与室内卫生要求的重要选择。基于新风量确定的基础和
ASHRAE62.1-2007中新风量的确定方法，对高密人群建筑的新风量指标随人员密度的变化特征进行了具体分析。结果表明，
针对 GB50019-2003 中的新风量参数和 ASHRAE62.1-2007 参考的建筑污染水平，以剧院、商场为代表的高密人群建筑需要
始终以降低新风能耗为首要问题；同时，宜对我国人员新风需求和建筑新风需求进行区别考虑，而降低我国建筑污染水平是
减少新风需求的重要途径，并且人员密度越高意义越明显。

Abstract Reasonable outdoor airflow rate is important for the balance of energy conservation and indoor health
requirement. Variation characteristic of outdoor airflow rate with indoor population density was analyzed for
high-density buildings according to the principle and calculation methods of outdoor airflow in ASHRAE62.1-2007.
The results show that reducing outdoor airflow energy consumption is the primal problem all along for theater and mall,
high-density building, with outdoor airflow parameter in GB50019-2003 and building pollution standard in
ASHRAE62.1-2007. Outdoor airflow required occupants and building should be treated respectively. And reducing
building pollution is one important way for lowering outdoor airflow requirement, the higher indoor population density
is, the greater signification is.
