建筑能源效率与操作和控制系统密切相关，与被动和主动系统的综合性能密切相关。特别是在高品质的新建筑中，后两个方面在设计阶段就已经实现了，必须考虑用户的角度，通过使用后评估获得，以减少在使用寿命期间的整体能源需求。本研究提出了一种创新和低成本的方法，通过使用有效用户的态度和需求作为反馈，通过使用后评估和优化能源运营来减少建筑物的能源需求。作为一个有意义的例子，所提出的方法应用于位于美国纽约州纽约市的一座多功能建筑，在那里评估了实际的使用条件。通过使用案例研究的数值模型进行动态模拟来测试该方法的有效性，并通过在建筑物上收集的实际监测数据进行校准。结果表明，对于选定的案例研究，该方法提供了优化的建筑能源操作，可以将HVAC，照明，房间电力和辅助供应的一次能源需求减少约21%。本文表明，该策略是减少建筑能源浪费的有效途径，特别是对于那些在概念设计-调试阶段表现不如预期的复杂高效建筑，特别是由于建筑移交后缺乏反馈。
Building energy efficiency is strongly linked to the operations and control systems, together with the integrated performance of passive and active systems. In new high quality buildings in particular, where these two latter aspects have been already implemented at the design stage, users’ perspective, obtained through post-occupancy assessment, has to be considered to reduce whole energy requirement during service life. This research presents an innovative and low-cost methodology to reduce buildings’ energy requirements through post-occupancy assessment and optimization of energy operations using effective users’ attitudes and requirements as feedback. As a meaningful example, the proposed method is applied to a multipurpose building located in New York City, NY, USA, where real occupancy conditions are assessed. The effectiveness of the method is tested through dynamic simulations using a numerical model of the case study, calibrated through real monitoring data collected on the building. Results show that, for the chosen case study, the method provides optimized building energy operations which allow a reduction of primary energy requirements for HVAC, lighting, room-electricity, and auxiliary supply by about 21%. This paper shows that the proposed strategy represents an effective way to reduce buildings’ energy waste, in particular in those complex and high-efficiency buildings that are not performing as well as expected during the concept-design-commissioning stage, in particular due to the lack of feedback after the building handover.
