10.15 Maintaining Healthy Indoor Air Quality

10.15 保持健康室内空气质量

English（英文原文）	中文（中文翻译）
IAQ is impacted by daily events within and outside the building. Without routine monitoring and maintenance, IAQ can degrade over time.	室内空气质量受建筑内外部日常事件的影响。如果没有例行的监测和维护，室内空气质量会随时间退化。

Green buildings maintain healthy IAQ over time. Strategies include:	绿色建筑长期保持健康的室内空气质量。策略包括：
• Routine, proactive maintenance of HVAC systems, including changing air filters regularly. Over time, filters become less effective as they trap particles. Therefore, project teams need to have processes in place to change filters regularly and to increase that frequency during major events that could impact IAQ, such as when pollen or smog levels are high, or during interior renovations that could kick up dust.	• 对暖通空调系统进行例行的主动维护，包括定期更换空气过滤器。随着时间的推移，过滤器在捕获颗粒方面效果会变差。因此，项目团队需要建立定期更换过滤器的流程，并在可能影响室内空气质量的重要事件期间（如花粉或雾霾水平较高时，或在可能扬起灰尘的室内装修期间）提高更换频率。
• Testing IAQ at a specific time (known as point-in-time testing), especially before occupants move in or return to a project after construction, renovations, or remodeling. Point-in-time testing can also be done in response to occupant reports of odd smells or unexplained symptoms.	• 在特定时间点测试室内空气质量（即所谓的时间点测试），尤其是在使用者入住或施工、翻新或装修后返回项目之前。也可以根据使用者报告的异味或不明症状进行时间点测试。
• Continuous indoor air monitoring, which is a way to automatically measure levels of indoor air pollutants frequently (often multiple times per hour) over a longer span of time. Equipment often measures CO and CO2, but other substances can also be monitored, including particulates, total VOCs, or a specific VOC like formaldehyde (HCHO). Project teams install sensors throughout the space and use the data they provide to better understand the space's IAQ and to identify and remediate sources of poor air quality.	• 持续室内空气监测，是一种在较长时间段内以较高频率（通常每小时多次）自动测量室内空气污染物水平的方法。设备通常测量CO和CO2，但也可以监测其他物质，包括颗粒物、总VOCs或特定VOC（如甲醛HCHO）。项目团队在整个空间内安装传感器，并利用其提供的数据更好地了解空间的室内空气质量，并识别和修复空气质量不佳的源头。
Example of using continuous air monitoring to improve IAQ: Using data from continuous indoor air monitors, a building operator may notice a spike in VOC levels that appears to correspond with the cleaning schedule. After changing cleaning protocols to use products with less-harmful chemicals, the operator can use the data to confirm that VOC levels now remain low.	使用持续空气监测改善室内空气质量的示例：建筑运营商可能利用持续室内空气监测器提供的数据发现，VOC水平的高峰似乎与清洁时间表相对应。在更改清洁规程以使用含有较少有害化学品的产品后，运营商可以使用数据确认VOC水平现在保持较低。
