建筑方案设计中的太阳辐射模拟研究

合理利用太阳能资源是实现建筑节能的重要技术措施。为更合理的利用太阳能,运用Ecotect软件精确地对太阳辐射定量分析,建立太阳能辐射分析模型,对住宅建筑的设计方案进行模拟研究。根据建筑的功能特点以及周边区域的自然环境,建立分析模型,为建筑进一步深化设计以及施工提供可靠依据。以武汉蔡甸区一栋低层钢结构住宅为例,通过建筑场地太阳辐射、遮阳构件、光伏系统以及蓄热墙体的模拟分析,对建筑设计方案进行优化,并分析评价方案优化后的建筑采光及节能效果,为工程师在设计建造过程中提供科学指南。

Simulation on Solar Radiation in Building Design

The solar energy application is an important technical measure for building energy con-servation. For a more rational use of solar energy, the solar radiation analysis model is established by Eco-tect software to simulate the residential building design. Through the construction of its own characteristics and regional natural environment for computer simulation, the paper provides a scientific basis for the latter construction. A low-rise steel structure residential building in Wuhan Caidian District, for example, the overall architectural design is optimized by simulating the solar radiation of building site, shading compo-nent, photovoltaic system and heat storage wall. And the scheme optimization of building lighting and ener-gy saving effect are analyzed and evaluated to guide engineers in the design phase of the decision-making.
