doi:10.13287/j.1001-9332.202310.020

Abstract

Abstract: Vertical greenery system (VGS) is a sustainable solution to promote building energy saving and emission reduction, mitigate the urban heat island effect, as well as a crucial component of urban ecological construction. We summarized four main mechanisms of the thermal effects of VGSs, including shading effect, evapotranspiration effect, thermal insulation effect, and wind control effect. We elucidated the effects of VGSs on building cooling and energy saving, and analyzed the cooling effects of VGSs on plant canopy and outdoor ambient air, as well as their influence on mitigating the urban heat island effect. Based on available research on the thermal effects of VGSs, we identified key directions for future research, aiming to expedite the development of green cities and achieve carbon neutrality.

Key words: vertical greenery system, thermal environment, cooling effect, building energy saving, influence mechanism
