The Usefulness of Climatic Maps of Built-Up Areas in Determining Drivers for the Energy and Environmental Efficiency of Buildings and External Areas

Abstract

Global Information Systems (GIS) are being used to provide data on a wide range of environmental issues, and in the area of climate studies they are being used to determine zones of towns and cities where there are good or poor external environments. From this analysis, planning guidelines can be drawn up to ensure that developments either enhance or do not deter from the environmental quality of the surrounding area. This paper proposes a method of extending the use of GIS climate mapping into the area of natural ventilation of buildings by establishing zones within towns or cities where the natural ventilation potential is quantified in terms of the likely reduction in pressure coefficients acting on the building facades. It concludes by proposing that, by incorporating pressure coefficient data along with noise density and pollution data into the urban climate mapping system, an enhanced environmental quality planning guidance can be established.
