摘要
建筑立体绿化对于夏热冬暖地区的建筑隔热降温优势明显,进而成为实现我国碳达峰、碳中和目标的潜在积极因素.对海南地区典型建筑立体绿化效果进行测试对比,定量分析立体绿化对屋面和墙体的隔热降温作用.研究表明:细叶结缕草种植屋面土壤层厚度每增加10 cm,温度能够降低0.5~1℃,隔热效果显著.垂直绿化对太阳辐照度的遮挡作用能够大幅度降低墙外表面的温度,进而影响建筑冷负荷.
Building three-dimensional greening has obvious advantages for building thermal insulation and cooling in hot summer and warm winter areas,and has become a potential positive factor affecting the realization of carbon neutralization goals in China.The thermal insulation effect of three-dimensional greening of typical buildings in Hainan is tested and quantitatively analyzed.The results show that for the roof planted with Korean velvet grass,the temperature can be reduced by 0.5~1℃with the increase of soil layer thickness of 10cm.Vertical greening has a certain shielding effect on solar radiation,which can greatly reduce the temperature of the outer surface of the wall,and then affect the building cooling load.
