Statistic Model of Urban Microclimates

Project Overview

This project investigates the effects of different built forms on wind environment, based on the measured data of a field study that was conducted on the University of Reading campus. In this study, the architectural forms of a street canyon, a semi-closure, a courtyard-like space and an open space were investigated for low-rise building complexes. For these architectural forms, the wind speed and wind direction at six measured locations were measured for a period of one year. A statistical analysis method was applied to identify key factors describing the effects of built form on wind environment. By using a factor analysis of the measured data, the meteorological and architectural layout factors have been determined for each architectural form above.

Background

The project ‘numerical and experimental study on urban microclimate’ funded by the EPSRC ( 2008-2011) has collected urban wind data sets over a twelve month period at the university campus site, which could be used for urban wind studies. A statistical analysis method is therefore proposed for study of the impact of urban forms on urban wind energy utilisation.

Key Objectives

  • to manipulate the data collected from six stations in the university campus;
  • to analysis the relationship of outdoor climatic parameters including temperature, humidity, velocity and solar radiation to the surrounding urban texture;
  • to identify key factors affecting urban wind environment;
  • to develop a statistical model of the urban wind environment.
