我们研究了加州大学校园里的一栋低能耗建筑。它具有高效的采暖、通风和空调（HVAC）系统，由双风扇/双风道变风量（VAV）系统组成。作为校园的主要建筑，它在2008年和2009年的夏季被列入了两次需求响应（DR）活动。由于冷冻水由中央电站的热能储存提供，冷却风扇在DR事件中发挥了关键作用。本文开发并校准了该建筑的EnergyPlus模型。我们将整个建筑和暖通空调风扇的能耗与模型预测进行了比较，以了解为什么2009年的需求节约远低于2008年。我们还使用研究建筑的模型模拟来评估预冷，预冷策略已被证明可以改善许多类型建筑的需求节约和热舒适。该研究表明，适当校准的EnergyPlus模型可以合理地预测灾难事件的需求节约，并且可以用于设计或优化灾难策略。
We have studied a low energy building on a campus of the University of California. It has efficient heating, ventilation, and air conditioning (HVAC) systems, consisting of a dual-fan/dualduct variable air volume (VAV) system. As a major building on the campus, it was included in two demand response (DR) events in the summers of 2008 and 2009. With chilled water supplied by thermal energy storage in the central plant, cooling fans played a critical role during DR events. In this paper, an EnergyPlus model of the building was developed and calibrated. We compared both whole-building and HVAC fan energy consumption with model predictions to understand why demand savings in 2009 were much lower than in 2008. We also used model simulations of the study building to assess pre-cooling, a strategy that has been shown to improve demand saving and thermal comfort in many types of building. This study indicates a properly calibrated EnergyPlus model can reasonably predict demand savings from DR events and can be useful for designing or optimizing DR strategies.
