ABSTRACT An important challenge for low energy buildings lies in the need to master airflows through the building envelope. This paper describes a campaign on 21 low-energy houses. First, we carried out an aeraulic measurement campaign on every dwelling including visual survey, airflow or pressure at the air-vents, ventilation duct airleakage, and acoustics measurements. Then, we selected 10 dwellings to carry out an indoor air quality winter campaign. This campaign included outdoor and indoor measurements of temperature, relative humidity, carbon dioxide, chemical pollutants (VOC, aldehydes). Inhabitant habits and building influence were studied through a complementary questionnaire survey. With this campaign, we were able to identify ventilation dysfunctions and to compare them with the national statistics on dwelling stock. The second part of the measurement campaign allowed us also to identify links between aeraulic diagnoses and indoor pollutant measurements.

法国 21 个低能耗住宅的通风性能和室内空气污染物诊断

摘要 低能耗建筑的一个重要挑战在于需要控制通过建筑围护结构的气流。本文描述了一项针对 21 座低能耗房屋的运动。首先，我们对每个住宅进行了空气测量活动，包括目视调查、通风口处的气流或压力、通风管道漏气和声学测量。然后，我们选择了 10 个住宅进行室内空气质量冬季运动。该活动包括室外和室内温度、相对湿度、二氧化碳、化学污染物（VOC、醛类）的测量。通过补充问卷调查研究了居民习惯和建筑影响。通过这项活动，我们能够识别通风功能障碍，并将其与全国住宅存量统计数据进行比较。
