Research on Outdoor Thermal Environment of Campus in Cold Area in Winter with Different Underlying Surfaces

Abstract

Thermal environment has many influences on people who use outdoor space. The thermal environment of university campus is an important part of educational living space. In campus planning and design, the impact of landscape design on the thermal environment should be considered. This paper measures the thermal environment of the campus of Xi’an Eurasia University and conducts questionnaire survey to obtain the Library and Nanshan Road, East Gate Square and Parking lot 4 different underlying surface characteristics of the impact on the thermal environment. The results show that the SET* correlation of different underlying surfaces: Library> East Gate Square> Nanshan Road > Parking lot. Shade, grassland, and water bodies can effectively reduce the average radiant temperature. Among them, the humidification and cooling effects of the shade are the best, and the cooling ability of the grass is second only to the shade. In the process of campus environment design, reasonable adjustment of the relationship between the shade of the grass and other underlying surfaces can effectively improve the outdoor thermal comfort of the campus in winter and create a comfortable outdoor activity place on the campus.
