摘　　要：为了研究模块式生态墙对建筑外墙光热环境的影响,以广州某已建成广场建筑为对象,对其模块式生态墙和裸墙的外墙温、湿度及光照强度进行了定量化对比研究.结果表明:模块式生态墙和裸墙相比,增湿降温效果明显,光照强度较低;相比于传统裸墙,模块式生态墙的外墙温度最多可降温5.1℃,可显著降低建筑能耗;模块式生态墙的相对湿度相比于传统裸墙,最高可增加23%;相比于传统裸墙,模块式生态墙的光照强度最多能降低99.4%,遮阳效果显著.模块式生态墙是一种有效的、主动的隔热节能方式,具有较高的节能综合效益.By taking a built square in G u a n g d o n g as the objective , the the exterior of the modular ecological wall are quantitatively compared with those based reveal the effects of the modular ecological wall on the exterior light-thermal environment of the building. T h e re-sults show that （1） as compared with the bare wall , the modular ecological wall can significantly increase the h u-midity and decrease the temperature , and it causes a lower illuminance; （2） in comparison with the bare wall ,the modular ecological wall reduces the exterior temperature by up to 5. 1 〇C in a day , and it can significantly re-duce the energy consumption of the building; （ 3 ） the relative humidity of the exterior of the modular ecologicalwall is at most 23% higher than that based on the bare wall; and （4） the modular ecological wall has a better shading effect than the bare wall; specifically, the former can reduce the illuminance by 99. 4 % at most. There-fore , the modular ecological wall is an effective, active w a y of thermal insulation and energy saving, which canproduce good comprehensive benefits in energy saving.
