HVAC系统占建筑能耗的38%。研究表明，至少有5-15%的浪费是由于未占用的空间被调节。我们的目标是通过改造暖通空调系统来最大限度地减少这种浪费，以实现房间级分区，每个房间都根据其占用情况进行单独调节。这将允许仅对占用的房间进行调节，同时节省用于调节未占用房间的能量。为了实现这一目标，必须预测打开或关闭通风口调节器对室温的影响。做出这样的预测是复杂的，因为天气对室温的影响比通风口寄存器的设置更大，因此很难隔离HVAC系统的影响。我们提出了一种动态估计天气对室温的热负荷并将其减去的技术，以便更直接地预测暖通空调系统的影响。
HVAC systems account for 38% of building energy usage. Studies have indicated at least 5-15% waste due to unoccupied spaces being conditioned. Our goal is to minimize this waste by retrofitting HVAC systems to enable room-level zoning where each room is conditioned individually based on its occupancy. This will allow only occupied rooms to be conditioned while saving the energy used to condition unoccupied rooms. In order to achieve this goal, the effect of opening or closing air vent registers on room temperatures has to be predicted. Making such a prediction is complicated by the fact that weather has a larger effect on room temperatures than the settings of air vent registers, making it hard to isolate the influence of the HVAC system. We present a technique for dynamically estimating the heat load due to weather on room temperatures and subtracting it out in order to predict the effect of the HVAC system more directly.
