Study on Street Space Microclimate Measurement and Improvement Strategy in Yangmeizhu Street in Beijing

Abstract

The paper studied the quality of public space in Yangmeizhu Street in Beijing through thermal comfort evaluation from the perspective of human perception evaluation, and analyzed microclimate measured data and dynamic simulation to put forward suggestions for improving the old city environment. Firstly, the research used portable meteorological station to monitor the microclimate data all day. Secondly, based on verification and fitting of present monitoring data and model data, the research established microclimate dynamic model for Yangmeizhu street by using Envi-met software platform. The main model indexes included temperature, humidity, solar radiation, wind speed and wind direction. Then the research analyzed high aspect ratio, green coverage rate and pavement materials in Yangmeizhu Street, and analyzed synthetically the relation between microclimate and public space.The paper proposed possible factors to affect the microclimate in the old city public space and improvement strategies for microclimate.
