这项研究估计了在美国写字楼库存中实施改善室内环境质量(IEQ)的方案的一些好处和成本。这些方案包括在L/S每人低于10或15的情况下增加通风量，在没有空气节能器和控制器的情况下增加室外空气节能器和控制器，消除冬季室内温度&23摄氏度，减少潮湿和霉菌问题。分析的情景的估计收益是巨大的，包括提高工作绩效，减少病态建筑综合症症状，减少缺勤，以及改善数百万上班族的热舒适性。一系列互不重叠的情景的年度潜在经济效益合计约为200亿美元。虽然量化估计具有很高的不确定性，但获得实质性好处的机会是显而易见的。一些改善IEQ的措施将在节省能源的同时改善健康或生产率，实施这些措施应该是最优先的。
This study estimates some of the benefits and costs of implementing scenarios that improve indoor environmental quality (IEQ) in the stock of U. S. office buildings. The scenarios include increasing ventilation rates when they are below 10 or 15 l/s per person, adding outdoor air economizers and controls when absent, eliminating winter indoor temperatures > 23 degrees C, and reducing dampness and mold problems. The estimated benefits of the scenarios analyzed are substantial in magnitude, including increased work performance, reduced Sick Building Syndrome symptoms, reduced absence, and improved thermal comfort for millions of office workers. The combined potential annual economic benefit of a set of nonoverlapping scenarios is approximately $20 billion. While the quantitative estimates have a high uncertainty, the opportunity for substantial benefits is clear. Some IEQ improvement measures will save energy while improving health or productivity, and implementing these measures should be the highest priority.
