ABSTRACT
Located in Jilin, one of the three provinces in Northeast China, Changchun belongs to the B zone of the severe cold area according to the national climate division, where the total solar radiation averages at 4787.4 MJ/m2 and the annual sunshine duration is 2,200-3,000 h. From this perspective, Changchun is an area with medium light resources, with a high probability of solar energy utilization and can achieve remarkable progress. For example, anti-season planting relying on absorption of solar energy by the exterior and thin-film materials is a proper means of utilizing solar energy. However, despite the rich solar energy resources
1 INTRODUCTION
Office buildings not only provide a comfortable working environment for people, but also beautify streets. In recent years, together with the constant development of building techniques and the increasing concerns of people over indoor environment comfort degree, energy consumption of office buildings has also marked an annual increase, thus aggravating environmental and energy issues. Currently, it has become one of the major problems inhibiting development of the building industry. Adopting feasible methods to cut energy consumption has been an issue of increasing concern. Although various techniques have popped up in response to the necessity of building energy conservation, capital cost and operating cost of these techniques are often extremely high, which are not suitable for some areas due to the local economic conditions. Adopting proper techniques for proper utilization of social energy resources in office building design has become one of the efficient methods to reduce office building energy consumption.
