摘  要   建筑室內(nèi)新風(fēng)量指標的合理確定是協(xié)調(diào)建筑節(jié)能與室內(nèi)衛(wèi)生要求的重要選擇。基于新風(fēng)量確定的基礎(chǔ)和
ASHRAE62.1-2007中新風(fēng)量的確定方法，對高密人群建筑的新風(fēng)量指標隨人員密度的變化特征進行了具體分析。結(jié)果表明，
針對 GB50019-2003 中的新風(fēng)量參數(shù)和 ASHRAE62.1-2007 參考的建筑污染水平，以劇院、商場為代表的高密人群建筑需要
始終以降低新風(fēng)能耗為首要問題；同時，宜對我國人員新風(fēng)需求和建筑新風(fēng)需求進行區(qū)別考慮，而降低我國建筑污染水平是
減少新風(fēng)需求的重要途徑，并且人員密度越高意義越明顯。

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.
