While residential energy and ventilation standards aim to improve the energy performance and indoor air quality (IAQ) of homes, their combined impact across diverse residential activities and housing environments has not been well-established. This study demonstrates the insights that a recently-developed, freely-available coupled IAQ-energy modeling platform can provide regarding the energy and IAQ trade-offs of weatherization (i.e., sealing and insulation) and ventilation retrofits in multifamily housing across varied indoor occupant activity and mechanical ventilation scenarios in Boston, MA. Overall, it was found that combined weatherization and improved ventilation recommended by design standards could lead to both energy savings and IAQ-related benefits; however, ventilation standards may not be sufficient to protect against IAQ disbenefits for residents exposed to strong indoor sources (e.g., heavy cooking or smoking) and could lead to net increases in energy costs (e.g., due to the addition of continuous outdoor air ventilation). The modeling platform employed in this study is flexible and can be applied to a wide range of building typologies, retrofits, climates, and indoor occupant activities; therefore, it stands as a valuable tool for identifying cost-effective interventions that meet both energy efficiency and ventilation standards and improve IAQ across diverse housing populations.

使用耦合模拟模型量化住房干预对室内空气质量和能耗的影响。

虽然住宅的能源和通风标准旨在改善房屋的能源性能和室内空气质量（IAQ），但它们在各种住宅活动和住宅环境中的综合影响尚未得到很好的确立。这项研究证明了新近开发的，免费提供的IAQ-能源耦合建模平台可以提供的见解，涉及在不同室内居住者活动的多户住宅中，气候化（即密封和隔热）和通风改造的能源和IAQ权衡和马萨诸塞州波士顿的机械通风场景。总的来说，发现设计标准所建议的综合风化和改善通风可以带来节能和与室内空气质量相关的好处；然而，通风标准可能不足以防止暴露于强室内源（例如，大量烹饪或吸烟）的居民受到IAQ的不利影响，并且可能导致能源成本的净增加（例如，由于增加了持续的室外空气通风）。本研究中使用的建模平台非常灵活，可以应用于各种建筑类型，改造，气候和室内居住活动。因此，它是确定符合能源效率和通风标准并改善不同住房人口的室内空气质量的经济有效干预措施的宝贵工具。本研究中使用的建模平台非常灵活，可以应用于各种建筑类型，改造，气候和室内居住活动。因此，它是确定符合能源效率和通风标准并改善不同住房人口的室内空气质量的经济有效干预措施的宝贵工具。本研究中使用的建模平台非常灵活，可以应用于各种建筑类型，改造，气候和室内居住活动。因此，它是确定符合能源效率和通风标准并改善不同住房人口的室内空气质量的经济有效干预措施的宝贵工具。
