Abstract
The thermal conditions within cities, as well as the energy efficiency of
buildings, are determined by the urban climate, which is in turn influenced by the
thermal-fluid characteristics of the built environment and particularly transfer
effects to the atmosphere. A good example of this interaction is the urban heat
island phenomenon. In this case heat generated from urban activities has a direct
impact on the urban microclimate, resulting in increased night time temperatures
and a reduction in the observed temperature range.
In order to understand the interaction between the built environment and the
urban microclimate, one needs to consider:
1. The energy efficiency of the built environment and mainly the
phenomena of heat transfer through radiation.
2. The ventilation capability of the urban environment and the effects of
different building geometries.
The study presented in this paper is concerned with the ventilation of the built
environment and involves Particle Image Velocimetry (PIV) measurements
under street canyon flow conditions in a flow channel.
Keywords: street canyon, urban heat island, Particle Image Velocimetry (PIV).
Keywords
