不同气候区建筑获得太阳辐射的动态分布特征

提高太阳能资源在建筑中的利用水平是减缓建筑对传统能源依赖程度的重要途径,也是推广可再生能源建筑应用的基本举措。基于全国五类气候分区代表性城市全年典型气象数据,结合计算模型研究分析了建筑屋面、东面、南面、西面、北面获得太阳辐射量的动态分布特征,确定了建筑各个方位利用太阳能资源的潜力。研究结果表明除了传统地发挥屋面利用太阳能的方法外,建筑立面接收太阳能辐射的能力也能达到良好的效果,即建筑立面利用太阳能具有较好的应用价值。

Dynamic Distribution Characteristics of Building Obtaining Solar Radiation in Different Climatic Zone

Improving the utilization of solar energy resources in architectures is an important way to abate the reliance of the conventional energy and also a basic move to promote the use of renewable energy in buildings.This article is based on typical climate data of some representative cities selected from the five climate zones.In order to determine the potentiality of the building to use solar energy,the dynamic distribution of the solar radiation measured from all directions of the building envelope that perpendicular to the ground is analyzed by mathematic model with climate data.The result indicate that,excepting what we all know that the roofs make good use of the solar energy,the ability of the building envelope to absorb the solar radiation also makes walls another good choice to gather the solar radiation.Thus,using the building envelope that perpendicular to the ground to improve the utilization of solar energy resources in building has very bright prospect for application.
