ABSTRACT Few field studies have evaluated ventilation strategies, such as temporarily increasing the ventilation rate, to counter the high pollutant-load from off-gassing of volatile compounds from new materials in these buildings. We reviewed longitudinal studies that measured both ventilation rate (i.e. fresh air change rate) and airborne concentration of total volatile organic compounds (TVOC). Rates of emission of TVOC follow a multi-exponential decay trend over time after completion of a building. A tri-exponential trend-was fitted by quantile regression. Although the ventilation rate is key to controlling airborne concentrations, it does not noticeably influence TVOC emission rates. Specifying low-emitting materials, or bake-out before occupancy, both have a significant impact on emission rates . The results can be used to assess and size energy-efficient practical ventilation strategies (such as demand-controlled ventilation) to keep the concentration of TVOCs within acceptable levels during hours of occupancy after completion of a new or renovated building.

新建和改建建筑的VOC排放率及通风的影响——综述和荟萃分析

摘要 很少有实地研究评估通风策略，例如暂时增加通风率，以应对这些建筑物中新材料释放的挥发性化合物所产生的高污染物负荷。我们回顾了测量通风率（即新鲜空气变化率）和空气中总挥发性有机化合物 (TVOC) 浓度的纵向研究。建筑物竣工后，TVOC 的排放率随时间呈多指数衰减趋势。三指数趋势-通过分位数回归拟合。虽然通风率是控制空气中浓度的关键，但它不会显着影响 TVOC 的排放率。指定低排放材料或在入住前烘烤，都会对排放率产生重大影响。
