需求控制通风（DCV）系统使用传感器，根据估计的在场人数，控制一个或多个空间的通风空气。虽然这项技术已经存在了一段时间，并且在理论上有多种好处，但人们对其在实际系统中的性能知之甚少，尤其是在复杂的多区域系统中。为了填补这一知识空白，进行了实地研究。研究结果表明，DCV确实节省了大量能源（主要是用于加热的燃料），而且对大多数车主来说通常是经济高效的。 它还通过重新调试证明了系统的改进，但表明在该技术的设计阶段发现了更大的缺陷。根据现场观察，还分享了设计和调试的最佳实践。引用:2016年冬季会议，佛罗里达州奥兰多，会议论文

Demand control ventilation (DCV) systems use sensors to control ventilation air to a space or spaces based on the estimated number of people present. Though the technology has been around for some time and has multiple theoretical benefits, less is known about its performance in real systems, especially complex multizone ones. A field study was implemented to fill this knowledge gap. Study results show that DCV does save significant energy (primarily the fuel used for heating), and is generally cost-effective for most owners. It also demonstrated improvement in systems through recommissioning, but showed that greater deficiencies are found in the design phase for this technology. Based on field observations, best practices for both design and commissioning are also shared.
