摘要

本文对办公建筑的动态光伏集成悬挑系统的能源效益进行了评价。动态PV集成悬架的好处是通过减少加热和冷却能源需求以及通过部署跟踪PV面板的现场可再生能源发电来结合能源效率。考虑了动态pv集成悬挑在不同设计和运行条件下的能量性能。具体来说,考虑了各种设计特征的影响,如悬挑深度、窗户大小、玻璃类型和暖通空调系统类型。此外,还评估了运行条件的影响,包括建筑物的位置和动态PV集成系统的控制策略,如负载跟踪,需求跟踪和PV跟踪。各种分析结果表明,动力悬挑的冷热能量需求主要受窗户玻璃类型和窗户悬挑深度的影响。分析表明,需求跟踪的使用最大限度地提高了动态pv集成悬架的能源性能,当部署到美国办公楼时。

Assessment of Dynamic Photovoltaic Shading Systems on Energy Performance of Commercial Buildings
In this paper, the energy benefits of dynamic PV-integrated overhang systems are evaluated for office buildings. The benefits of dynamic PV-integrated overhangs combined energy efficiency by decreasing both heating and cooling energy demand and on-site renewable power generation by deploying tracking PV panels. The energy performance of dynamic PV-integrated overhangs is considered for various design and operation conditions. Specifically, the impacts of various design features are considered such as overhang depth, window size, glazing type, and HVAC system type. Moreover, the effects of operating conditions are assessed including the location of the building and the control strategy of the dynamic PV-integrated systems such as load tracking, demand tracking, and PV tracking. The results of the various analyses indicate that the heating and cooling energy demands of the dynamic overhangs are mostly affected by the window glazing type and window overhang depths. The analysis shows that the use of demand tracking maximizes the energy performance of the dynamic PV-integrated overhangs when deployed to US office buildings.
