增湿效应较为明显的夏季对南京万荣立体绿化研发中心办公楼
垂直绿化进行研究,通过测量温度、湿度等客观环境数据,以
PMV-PPD作为人体舒适度评价指标,分析不同影响因子对温
湿度变化趋势及人体舒适度的影响。结果表明:实施垂直绿化
的测量点外墙降温3.72℃,室内降温7.45℃;使用模块式垂
直绿化比网架式垂直绿化降温增湿效果更明显,而使用网架式
垂直绿化的室内外温差更大,温差可达4.18℃;研究区域内
木屋东北面墙体温度略高于西北面,办公楼东南面温度高于西
南面,且南向墙体温度整体较高;无垂直绿化建筑PMV>2、
PPD接近100%,而办公楼和木屋的PPD相对较低,人体舒适度

Effect of Vertical Greening in Summer on Human Comfort in Nanjing |

Abstract: |
In order to explore the influence of vertical greening
on human comfort in Nanjing, the Wanrong Three-dimensional
Greening Research and Development Center office building was
studied in the summer when the effect of cooling and humidification
was more obvious. By measuring the objective environmental
data such as temperature and humidity, taking PMV-PPD as the
evaluation index of human comfort, the influence of different
factors on the change trend of temperature and humidity and
human comfort is analyzed. The results show that the temperature
of the outer wall of the measuring point where vertical greening is
implemented is 3.72°C lower, and the indoor temperature is 7.45°C
lower; the use of modular vertical greening has lower temperature
and higher humidity than the grid-type vertical greening, and the
indoor and outdoor temperature difference using the grid-type
vertical greening can reach 4.18°C; the temperature of the northeast
wall of the wooden house in the study area is slightly higher than
that of the northwest, the temperature of the southeast of the office
building is higher than that of the southwest, and the temperature
of the southward wall of the office building is generally higher;
PMV>2 for buildings without vertical greening, and PPD is close
to 100%, while PPD of the office building and wooden house is
relatively low, and the state of human comfort is ideal. Vertical
greening has a significant cooling and humidifying effect. When
designing vertical greening, it can start from the form and direction
of vertical greening, so as to improve human comfort. |
