Building Environment Simulation Of Solar Decathlon

Solar Decathlon is sponsored and held by the America Department of Energy, which is an international competition combined application of solar energy, energy-saving and emission-reduction with building design. It is the "Olympic games" of the science and technology sector. The competition hoped that with the help of the world’s top R&D and creative of design team, would combined energy-saving with architecture-design in new ways, and would design, construct and operate a attractive solar residential space with high efficiency and energy-saving. Which proves that houses only rely on solar energy could also be functional, comfortable and sustainable living space.The papers is based the participated design of Xiamen University in the Solar Decathlon (2013) in Datong, Shanxi. Quantified the effect of architectural design to the indoor environment. Through environment simulation software Ecotect to discuss the effect of shading design to the interior light environment, via ventilation simulation software Phonics to improve the design of ventilation, and by building energy simulation software Designbuilder to guide the design of energy balance. The papers is aimed at finding a way to use existing architectural environment simulation software guidance and feedback design method, which is based on "solution adjustment-again simulation" method over and over again, to guide the scheme optimization. At the same time, the competition of SD request the completion plan be constructed, also provide a basis for the fact that this method is feasible or not.SD is an expensive building scientific and technological competition. In the design of the Sunny Inside, more consideration is give to how to use "high-tech" and "appropriate technology" in balance. There are both the design elements of traditional Chinese architecture-courtyard, and also the modern building technology-the combination of solar energy. When compared to the costly and expensive installation "high technology" works, Sunny Inside seems more to consider how to promote "suitability solar technology" in China. Sunny Inside as a prototype, has a strong adaptability, through the design of architecture and technology optimization and transformation, if possible, would be extended to the broad masses of urban and rural areas in China.
