摘要

现代高层建筑广泛采用大面积玻璃幕墙,以达到吸引人的建筑美学效果。建筑美学、建筑能耗和玻璃幕墙的太阳能收集之间存在固有的冲突。在这项研究中,我们引入了一种新型动态垂直光电一体化建筑围护结构(dvPVBE)来解决这些矛盾,这种围护结构具有非凡的灵活性,可根据天气变化调整板条角度和百叶窗位置,具有卓越的建筑美学效果和显著的节能潜力。针对 dvPVBE 的不同应用场景,提出了三种分层控制策略:发电优先(PGP)、自然采光优先(NDP)和节能优先(ESP)。此外,还在 dvPVBE 的模拟中进一步分析了 PGP 和 ESP 策略。使用 EnergyPlus 对一个集成了 dvPVBE 的办公房间进行了建模。在 PGP 和 ESP 控制策略下,研究了 dvPVBE 对提高建筑能效的影响以及相应的最佳板条角度。结果表明,与静态光伏(PV)百叶帘相比,在北京应用 dvPVBE 可为办公用房提供高达 131% 的年能源需求,并显著提高年净能源产出至少 226%。这种新型 dvPVBE 的概念提供了一种可有效调节热负荷、日光渗透率和发电量的可行方法。

A New Dynamic and Vertical Photovoltaic Integrated Building Envelope for High-Rise Glaze-Facade Buildings

Substantially glazed facades are extensively used in contemporary high-rise buildings to achieve attractive architectural aesthetics. Inherent conflicts exist among architectural aesthetics, building energy consumption, and solar energy harvesting for glazed facades. In this study, we addressed these conflicts by introducing a new dynamic and vertical photovoltaic integrated building envelope (dvPVBE) that offers extraordinary flexibility with weather-responsive slat angles and blind positions, superior architectural aesthetics, and notable energy-saving potential. Three hierarchical control strategies were proposed for different scenarios of the dvPVBE: power generation priority (PGP), natural daylight priority (NDP), and energy-saving priority (ESP). Moreover, the PGP and ESP strategies were further analyzed in the simulation of a dvPVBE. An office room integrated with a dvPVBE was modeled using EnergyPlus. The influence of the dvPVBE in improving the building energy efficiency and corresponding optimal slat angles was investigated under the PGP and ESP control strategies. The results indicate that the application of dvPVBEs in Beijing can provide up to 131% of the annual energy demand of office rooms and significantly increase the annual net energy output by at least 226% compared with static photovoltaic (PV) blinds. The concept of this novel dvPVBE offers a viable approach by which the thermal load, daylight penetration, and energy generation can be effectively regulated.
