Research On Gymnasium Design With Low-energy Consumption In Severe Cold Area Of China

Due to China’s continental climate, the issue of gymnasiums’ energy consumption in severely cold regions is more serious. The energy consumption of buildings in this region accounts for more than half of the total. Due to the huge capacity and strict indoor environment requirements, gymnasium buildings cost great energy. In order to reduce energy consumption and negative effect to environment, more and more global architects realize that it is necessary to design buildings in a green and energy-saving way. Focusing on natural environment and sustainable development design, maximizing energy conservation is the responsibility of architects. As the meanwhile of optimizing the quality of the indoor environment, concern on the natural environment and sustainable development design.
