Some low cost but practical passive and active energy saving technologies have been successfully used in an office building energy saving technological transformation in Tianjin. The energy consumption and operating cost have been compared and analyzed before and after the transformation. The results show that the building energy consumption has decreased from 52.6 kWh/(m2·a) to 36 kWh/(m2·a), having reached the level of international ultra-low energy consumption building. The operating cost has been reduced from 96 RMB/(m2·a) to 30RMB/(m2·a), and the energy consumption and maintenance account for the most of life time cycle cost.
