Abstract

This study deals with the indoor air quality (IAQ) measured and perceived in a demonstration building via a smart sensor. The analysis subject targeted includes the following main air pollutants, viz., CO₂, VOCs, formaldehyde, benzene, CO, PM_2.5, and comfort parameters such as air temperature, and relative humidity. These were recorded during three campaigns. It turned out that the CO₂ level was higher during the first occupation period, while measurements of other air pollutants were low. Besides, it turned out that the ventilation system could regulate control the airflow based on the CO₂ concentrations only. However, this was upset occupants comfort.

摘要

本研究涉及通过智能传感器在示范建筑中测量和感知的室内空气质量 (IAQ)。针对的分析对象包括以下主要空气污染物，即CO ₂、VOCs、甲醛、苯、CO、PM _2.5，以及空气温度、相对湿度等舒适参数。这些是在三个活动中记录的。结果表明，在第一个占领期间， CO _{2水平较高，而其他空气污染物的测量值较低。}此外，事实证明，通风系统可以仅根据 CO ₂浓度来调节控制气流。然而，这却让住户感到不安。
