Research on the Influence of Vertical Green of Envelope Structure on Indoor Thermal Environment - - A study of Zhengzhou city

Abstract

In this paper, control variable comparative test was employed to study the effect of the vertical greening of the envelope structure on the indoor thermal environment of Zhengzhou city. Two rooms with exactly the same structure except for the vertical greening were used as the experimental group and the reference group. The experimental results found that when vertical greening was adopted, the average temperature of the outer surface of the wall was decreased by 7.6 °C and 0.4 °C during the day and night, while the average indoor air temperature was decreased by 1.8 °C and 0.1 °C respectively. Therefore, we also found out that the average indoor air relative humidity of green vertical room was increased by 3.9% and 0.2% during the day and night with respect to the reference room. It shows out that vertical greening can effectively alleviate overheating, stabilize indoor environmental humidity, and improve the indoor thermal environment significantly.
