摘要办公楼能耗占总能耗的很大一部分。在这项研究中，基于太阳能系统的改造措施，如采光控制系统（DCS），特隆贝墙（TW）和光伏（PV）系统，位于美国俄亥俄州代顿市的办公楼建模。eQuest是一种能源建模工具，用于分析拟议的单一改造措施以及组合措施的经济和环境影响，以确定优化的建筑节能机会。与基线能源消耗相比，采用单一的能源效益措施，如光伏、DCS、TW和窗户的悬垂/翅片，分别可减少约25、10、9和1个百分比的能源。从经济角度来看，悬垂和鳍提供了大约1年的最佳回报时间。其他基于太阳能系统的改造措施，如TW、DCS和PV，分别可以提供1.5年、2.5年和12年的经济简单回报。光伏发电虽然能最大限度地节约能源，减少二氧化碳排放，但却被证明是成本最高的选择。采用联合系统以及50千瓦的屋顶光伏阵列，办公楼的能耗降低了45%。
Abstract Office buildings are responsible for a great portion of total energy consumption. In this study, solar system based retrofitting measures such as daylighting control system (DCS), Trombe wall (TW) and photovoltaic (PV) systems are modeled to an office building located in Dayton, Ohio, United States. An energy modeling tool, eQuest is utilized to analyze the economic and environmental impacts of the proposed single retrofitting measures along with the combined measure to identify the optimized building energy reduction opportunity. Compared to the baseline energy consumption, adopting single energy efficiency measures such as PV, DCS, TW, and overhangs/fins to windows results in about 25, 10, 9, 1 percentages of energy reduction respectively. In terms of economic perspectives, overhang and fins provide the best simply payback time around 1 year. Other solar system based retrofitting measures such as TW, DCS and PV can provide economic simple payback with 1.5, 2.5, and 12 years respectively. PV turned out to be the most costly options although it provides the largest energy savings which lead to the largest CO2 reductions. Adopting the combined system along with 50 kW photovoltaic array to the rooftop results in 45 percent office building energy reduction.
