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 Guangdong as the objective,the temperature,humidity and illuminance of the exterior of the modular ecological wall are quantitatively compared with those based on the bare wall,so as to reveal the effects of the modular ecological wall on the exterior light-thermal environment of the building.The re- sults show that (1) as compared with the bare wall,the modular ecological wall can significantly increase the hu- 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℃ 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 ecological wall 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 way of thermal insulation and energy saving,which can produce good comprehensive benefits in energy saving.
