Sensitive Analysis of Factors on Thermal Environment in the Waterfront Area

Abstract

As one of the complex underlying surfaces, the water body improved the local thermal climate in the surrounding area especially on water vapor diffusion and temperature. Therefore, in this paper, taking the water effect and factor analysis as the research object, based on the CFD method, key factors were analyzed which influence thermal and humidity environment in the waterfront areas. The factors mainly discussed in this paper are building type, building floor area ratio, embankment height, distance from water body, and landscaping. Each factor includes five levels. The results showed that the building floor area ratio and embankment height were the most significant factors for the vapor diffusion, followed by landscaping and the building type had the minimum influence. For the temperature, all factors had no obvious gap. Besides, the building floor area ratio was strongly linear correlated to water vapor diffusion but poorly to temperature.
