dc.description.abstractBuilding progress consists of master planning, design detail, construction, acceptance and management phases. Due to lack of communication, there are many gaps between the adjacent phases in building progress, such as, the big gap between construction and acceptance phase. The gaps lead to miss part of design intent when buildings were functioned. Although many prevailing evaluation systems like GOBAS or LEED mean to cover a whole building progress, in reality, they only pay much attention to design phase and generally ignore commissioning phase after construction. It leads an inefficiently facility management of HVAC systems and components. Energy diagnose and re-commissioning by on-site measurement can solve these problems, to improve systems' efficiency and bridge the gap between acceptance and management phase, finally realize a real green building. In this paper, it presents a case study result of applying this approach in a green office building in Beijing and shows how re-commissioning and energy diagnose contribute significantly to reach a real green building for long-term functioning. That Green Office Building was certified as Golden Level by LEED, and evaluated as Level B by GOBAS. All these evaluation did before construction phase. But the actual power consumption, 74kWh/m2.a, is twice as the designed consumption, and is only a bit less than other common office building. One month on-site measurement and half a year of data collected after acceptance phase show that some energy-efficient equipment do not run in a proper way. By re-commissioning, most of the systems in the Green Building work well.en_US
