绿化遮阳对夏热冬暖地区建筑热环境影响分析

地处夏热冬暖地区的广西大部夏季湿热漫长,建筑空调制冷能耗高。通过对广西南宁市建筑外遮阳使用情况的调研,得到建筑立体绿化遮阳和非绿化外遮阳的使用情况。同时,选择一栋典型建筑,对其进行绿化遮阳及非绿化遮阳外墙表面温度的测试,分析绿化遮阳形式对建筑热环境的影响,探讨建筑绿化遮阳对广西乃至整个夏热冬暖地区建筑节能的作用。

Impact of Green Shading to Building Thermal Environment in Hot Summer and Warm Winter Area

Guangxi, locates in the hot summer and warm winter area, its summer is hot and humid and lasts for a long period, resulting in higher energy consumption for air-conditioning cooling system for buildings. Based on the investigation in Nanning, the building three-dimensional green shading and non-green external shading are obtained. A typical building with green and non-green external shading system is selected in Nanning for the wall surface temperature testing. The impact of the green shading on the thermal environment of the building is analyzed, as well as the effect of green shading on the building energy conservation in Guangxi, even the whole hot summer and warm winter area.
