建筑环境绿化降温效果实测

系列实测表明,墙体绿化、小区绿化、树木遮阳具有不同程度的降温效果。墙体绿化的降温效果与墙体的蓄热能力、墙体朝向、气候条件等因素有关,植物蒸腾吸收热量的贡献要比遮挡太阳辐射减少热量的贡献大。综合环保、技术、经济因素,建筑小区绿化应该以树木为主导。树木遮阳能显著降低室内温度,减少室内温度波动,为夜间自然通风创造更好的条件。

Measurements of Cooling Effect of Building Environment Greening

A series of measurement s showed that wall different degree of cooling effect. The cooling effect of wall greening,community greening and trees shading had greening was related to factors such as heat storage capacity,the orientation of the wall and climatic conditions. By comparing,the heat reduced by sheltering the solar radiation was smaller than the heat absorbed by plant transpiration. Comprehensive considering environment, technology and economics,the building environment greening should take trees as the priority. The trees shading can significantly drop indoor temperature and its fluctuation,also can create better condition for natural ventilation at night.
