摘要

鉴于 COVID-19 的出现,人们对生活和工作场所的室内空气质量数据越来越焦虑。使用消费级空气质量监测仪获取这些数据,已成为一种让建筑用户了解自己所处空间通风效果的方式。方法:测试了 14 种面向消费者销售的低成本空气质量设备(7 种类型,每种产品 2 种):AirBird、Airthings View Plus、Aranet4 Home、Awair Omni、Eve Room、Laser Egg + CO2 和 Purple Air PA-1。研究重点是准确性和易用性,采用了三种方法:在低成本实验室环境中测试二氧化碳的准确性;与经过校准的研究级仪表进行比较,以测试颗粒物(PM2.5)、温度和相对湿度;在住宅环境中进行短期现场测试,以了解向用户提供的反馈的质量。测试结果在准确性方面,所有设备的温度、相对湿度和二氧化碳都在可接受的范围内,只有一个品牌在测试 PM2.5 时的结果达到了研究级监测仪的准确性阈值。在可用性方面,在设备或智能手机应用程序的响应时间和数据可视化方面存在显著差异。结论:虽然室内空气质量数据的准确性很重要,但对于面向消费者销售的低成本空气质量设备来说,同样重要的是,数据的呈现方式必须能够帮助人们做出决策并改变室内环境。我们的结论是,响应时间、用户界面、数据共享和可视化都是重要的参数,如果研究只关注准确性,可能会忽略这些参数。此外,还必须考虑设备的设计,包括其外观、尺寸、便携性、屏幕亮度以及声音或灯光警告。测量行为非常重要,更多的研究应关注用户如何解读建筑性能数据并对其做出反应。

Evaluating Indoor Air Quality Monitoring Devices for Healthy Homes
In light of COVID-19, people are increasingly anxious about indoor air quality data in places where they live and work. Access to this data using a consumer-grade air quality monitor has become a way of giving agency to building users so that they can understand the ventilation effectiveness of the spaces where they spend their time. Methods: Fourteen low-cost, air quality devices marketed to consumers were tested (seven types, two of each product): AirBird, Airthings View Plus, Aranet4 Home, Awair Omni, Eve Room, Laser Egg + CO2, and Purple Air PA-1. The study focus was accuracy and useability using three methods: a low-cost laboratory setting to test accuracy for CO2; a comparison to a calibrated, research grade meter for particulate matter (PM2.5), temperature, and relative humidity; and short-term field testing in a residential environment to understand the quality of feedback given to users. Results: Relating to accuracy, all devices were within acceptable ranges for temperature, relative humidity, and CO2, and only one brand’s results met the accuracy threshold with the research grade monitor when testing PM2.5. In terms of usability, a significant variation in response time and data visualization was found on the devices or in the smartphone applications. Conclusions: While accuracy in IAQ data is important, in low-cost air quality devices marketed to consumers it is just as important that the data be presented in a way that can be used to empower people to make decisions and modify their indoor environment. We concluded that response time, user-interface, data sharing, and visualization are important parameters that may be overlooked if a study just focuses on accuracy. The design of the device, including its appearance, size, portability, screen brightness, and sound or light warning, must also be considered. The act of measuring is important, and more studies should focus on how users interpret and react to building performance data.

期刊介绍: BUILDINGS content is primarily staff-written and submitted information is evaluated by the editors for its value to the audience. Such information may be used in articles with appropriate attribution to the source. The editorial staff considers information on the following topics: -Issues directed at building owners and facility managers in North America -Issues relevant to existing buildings, including retrofits, maintenance and modernization -Solution-based content, such as tips and tricks -New construction but only with an eye to issues involving maintenance and operation We generally do not review the following topics because these are not relevant to our readers: -Information on the residential market with the exception of multifamily buildings -International news unrelated to the North American market -Real estate market updates or construction updates
