Abstract Hybrid ventilation systems have become increasingly attractive, because they are considered to provide good indoor air quality (IAQ) with low energy consumption. In this study, we evaluate the performance of a hybrid ventilation system (operating on both mechanical and natural ventilation mode) by monitoring the IAQ (e.g. temperature, humidity, CO2 levels) and the energy consumption of a multifamily building. We then investigate occupants' window-opening behavior during the heating season by means of window sensors. The results show that the hybrid ventilation system maintains a good level of IAQ while being energy efficient. We also find that occupants’ window-opening behavior is significantly affected by indoor temperature and CO2 concentration. We therefore recommend adopting them as input parameters when designing ventilation control strategies to enhance the performance.

节能混合通风系统性能评估及居住者控制窗户行为分析

摘要 混合通风系统变得越来越有吸引力，因为它们被认为以低能耗提供良好的室内空气质量 (IAQ)。在本研究中，我们通过监测 IAQ（例如温度、湿度、CO2 水平）和多户建筑的能源消耗来评估混合通风系统（在机械和自然通风模式下运行）的性能。然后，我们通过窗户传感器调查居住者在供暖季节的开窗行为。结果表明，混合通风系统在节能的同时保持了良好的室内空气质量水平。我们还发现居住者的开窗行为受室内温度和二氧化碳浓度的显着影响。
