Summary:
The objective of this research is to assess and analyze the bioclimatic
conditions in human thermal bioclimatic conditions in the Athens University
Campus (AUC) using urban micro models such as RayMan. The quantification of
human thermal sensation in such a place was considered of great significance
due to the great gathering of student body and members of University. The
quantification of the bioclimatic conditions was succeeded by the estimation of
the Physiologically Equivalent Temperature (PET), which is a bio-climatological
index based on the human energy balance. We made field measurements of air
temperature, relative humidity, wind speed and total solar irradiance, for
different sites of the examined micro urban environment, in order to calculate
PET, during January-July 2013. Additionally, the calculations were done by
different sky view factors, and compared to a reference site (Meteorological
station of Laboratory of Climatology and Atmospheric Environment, University of
Athens). The global radiation was transferred to the examined sites with the
RayMan model, which considers the sky view factors for the adaptation of the
radiation fluxes to simple and complex environments.
The findings revealed significant differences in PET quantification, even in
very close sites, which differs in sky view factor and buildings orientation
and height. Besides, this study highlights the beneficial impact of trees and
green cover in a complex environment, indicating that planting of trees among
other actions could be the solution of mitigating strong/extreme heat stress,
improving the quality of living in cities.
