FIELD INVESTIGATION AND MODEL BASED ENERGY BENCHMARKING OF OFFICE BUILDINGS IN BEIJING, CHINA

J. An, D. Yan

Abstract: Due to the characteristics of big volume and high energy consumption, the energy conservation of office buildings is one of the most important parts in the field of building energy efficiency and attracts increasing attention all over the world. The energy benchmarking plays an important role in the public energy conservation work. However, in nowadays, there are so many differences between different buildings, which could influence the energy consumption significantly, such as indoor occupant number, heat productivity of lighting and facility, how to obtain the reasonable energy consumption benchmarking is very difficult. With the energy conservation work going further, the importance of a more reasonable benchmarking methodology become outstanding for building energy consumption at this stage There are some methods (e.g., Energy Star, LEED) to give out the building energy consumption benchmarking nowadays, which are reviewed in this paper firstly, and some common and key issues are summarized and discussed. Then, a novel way to get the building energy consumption benchmarking and to judge the energy consumption conditions of different buildings with considering the reasonable characteristics of each building is proposed in this study. As one important part of office buildings, the government buildings need to be paid more attention to in energy conservation. Based on detailed investigation and simulation, the benchmarking work for government office buildings in Beijing, China is taken as an example to validate the efficiency of this methodology by coming up different benchmarking to judge their energy consumption in the same standard.
