室内空气质量是健康状况的重要预测指标，尤其是在低收入人群中。目前尚不清楚“绿色”建筑的最新趋势如何影响室内暴露状况。在连续两年，我们对两个公共房屋发展项目的绿色和常规（对照）公寓住户进行了环境抽样、验房和健康问卷调查。一部分参与者在从传统住房到绿色住房或从传统住房到传统住房的过程中被跟踪。我们测量了空气动力学直径小于2.5 μ m的颗粒物（PM2.5）、甲醛、二氧化氮（NO2）、尼古丁、二氧化碳（CO2）和空气交换率（AER），采样周期为7天。在多变量模型中，我们观察到绿色家庭中PM2.5 NO2和尼古丁的浓度（分别为57%、65%和93%）比对照家庭低（p = 0.032、p < 0.001和p = 0.003），霉菌、害虫、通风不足和闷闷的报告也更少。甲醛和CO2的差异无统计学意义。绿色建筑的AER略低（p = 0.109）。绿色住宅的参与者经历了47%的病态建筑综合征症状（p < 0.010）。我们观察到，在搬进绿色住房的参与者中，多次室内暴露显著减少，健康状况得到改善，这表明多层次住房干预有可能改善居民的长期健康。
Indoor air quality is an important predictor of health, especially in low-income populations. It is unclear how recent trends in "green" building affect the indoor exposure profile. In two successive years, we conducted environmental sampling, home inspections, and health questionnaires with families in green and conventional (control) apartments in two public housing developments. A subset of participants was followed as they moved from conventional to green or conventional to conventional housing. We measured particulate matter less than 2.5 mu m aerodynamic diameter (PM2.5), formaldehyde, nitrogen dioxide (NO2), nicotine, carbon dioxide (CO2), and air exchange rate (AER) over a seven-day sampling period coincident with survey administration. In multivariate models, we observed 57%, 65%, and 93% lower concentrations of PM2.5 NO2, and nicotine (respectively) in green vs control homes (p = 0.032, p < 0.001, p = 0.003, respectively), as well as fewer reports of mold, pests, inadequate ventilation, and stuffiness. Differences in formaldehyde and CO2 were not statistically significant. AER was marginally lower in green buildings (p = 0.109). Participants in green homes experienced 47% fewer sick building syndrome symptoms (p < 0.010). We observed significant decreases in multiple indoor exposures and improved health outcomes among participants who moved into green housing, suggesting multilevel housing interventions have the potential to improve long-term resident health.
