Influence of Vegetation System on Outdoor Wind Environment of a Nursing Home

Abstract

With the rapid growth of aging population in China, researchers have paid more attention to the aging planning and architectural design of elderly community. As the particularity of elderly people, they have higher demand on the comfort and safety of the outdoor wind environment, and the outdoor vegetation system has a great contribution on improving outdoor wind environment which has been proved. In this study, the influence of vegetation system on outdoor wind environment in extreme weather of a nursing home has been quantitatively investigated according to CFD methods. The parameters related to the wind environment including average wind velocity and its distribution has been calculated. Results showed that vegetation system could improve the outdoor wind environment significantly, especially planting shrub and grass. After planting deciduous and evergreen arbors, shrub and grass, the average wind velocities of all the living and activity regions decreased below to 1.5m/s, and area proportion of the regions with low wind velocity increased up to 75%.
