儿童哮喘目前是美国最常见的慢性病，低收入家庭的儿童受到的影响不成比例。健康负担增加的部分原因是负担得起的住房质量较低和维护不足。在现有的负担得起的住房中进行“绿色”改造以提高能源效率和增加通风的运动，为提供能够解决这些健康差距的具有成本效益的干预措施提供了机会。我们将室内空气质量建模与先前开发的儿童哮喘恶化的离散事件模型相结合，以模拟在马萨诸塞州波士顿的一个经济适用房场地实施的不同类型的能源改造的效果。模拟结果表明，如果通过机械通风来补偿节能空气收紧导致的空气交换减少，则改造会带来整体更好的健康结果和医疗成本节约。尤其是当暴露在室内烟草烟雾和密集的煤气炉烹饪时，这种改造将导致平均每年节省200美元以上的成本，而如果没有机械通风，同样的儿童将经历几乎200美元/年的医疗保健利用成本的增加。本文采用室内空气质量建模和离散事件建模相结合的方法，可以将健康影响纳入经济适用房能源改造的成本效益分析中。网上版载有补充材料，可在10.1186/s12940-021-00699-x查阅。
Pediatric asthma is currently the most prevalent chronic disease in the United States, with children in lower income families disproportionately affected. This increased health burden is partly due to lower-quality and insufficient maintenance of affordable housing. A movement towards ‘green’ retrofits that improve energy efficiency and increase ventilation in existing affordable housing offers an opportunity to provide cost-effective interventions that can address these health disparities. We combine indoor air quality modeling with a previously developed discrete event model for pediatric asthma exacerbation to simulate the effects of different types of energy retrofits implemented at an affordable housing site in Boston, MA. Simulation results show that retrofits lead to overall better health outcomes and healthcare cost savings if reduced air exchange due to energy-saving air tightening is compensated by mechanical ventilation. Especially when exposed to indoor tobacco smoke and intensive gas-stove cooking such retrofit would lead to an average annual cost saving of over USD 200, while without mechanical ventilation the same children would have experienced an increase of almost USD 200/year in health care utilization cost. The combination of indoor air quality modeling and discrete event modeling applied in this paper can allow for the inclusion of health impacts in cost-benefit analyses of proposed affordable housing energy retrofits.
