Field Research and Study of Campus Thermal Environment in Winter in Severe Cold Areas

Choosing the second campus of Harbin Institute of Technology as a study example, the paper tested its outdoor environment variables (air temperature, wind speed, black globe temperature and solar radiation intensity) under different underlying surfaces in winter, and generated the result of how different underlying surfaces influence the thermal environment. Based on the test, the paper reaches the following results: temperature difference between hard surface with solar radiation and hard surface without solar surface is 5 ℃; air temperature changes of ice surface and snow surface are relatively big, and under solar radiation, their average temperatures are a little higher than other surfaces; under the same condition, snow surface's humidity is a little higher than that of ice surface; and architecture arrangement has big influence on wind environment.
