Office building development in urban China has grown very rapidly in recent years, and this trend will continue in the future against the background of fast national economic growth. However, knowledge about China’s urban office buildings is very limited to date; especially characteristics of the environmental sustainability performance of this sector, such as energy use pattern, context-specific technical strategies and effective policies to improve its performance. It is evident that China has not yet achieved substantial results in its efforts to improve environmental sustainability in urban office buildings. Will urban office building construction lock in negative environmental impacts for the future? This dissertation presents a holistic approach to methods for the assessment of core environmental sustainability issues within the scope of office building in urban China, mainly from the perspective of building life cycle primary energy consumption and C02 emissions. It explores a series of prescribed measures and scenarios to assess cost-effective reduction of the office building sector’s environmental impacts, based on an integrated Excel spreadsheet-based method. The overall conclusions are: 1. The simplified technique for life cycle assessment of environmental sustainability can be effectively adopted at the early design stage as a practical tool to help designers understand the life cycle performance of various current office construction choices in this important sector. 2. For typical “wasteful” cases, a reduction of nearly 40% of the life cycle primary energy reduction (LCPE) can be achieved with less than three years of discounted payback periods through the combination of the selected cost-effective measures. 3. Based on the study of the maximum value of technical reduction between the average value of a wasteful case and the improved case adopting an overall improvement package in each office type, estimation shows that around 11.3 million MJ of annualised LCPE is locked in current existing office buildings, which takes nearly half of the total annualised LCPE in the sector and around 10% of the total primary energy use in the commercial building sector.
