Abstract
Mean Radiant Temperature (MRT) is one of the most relevant human bioclimatic indices, particularly suitable for assessing the influence of climatic parameters on thermal comfort outdoors. MRT can be calculated either based on physical measurements, carried out using a pyranometer and a pyrgeometer for quantifying short and long wave radiation fluxes, either by computational simulation. The first method is accurate, however it requires the measurement of radiant fluxes from six directions, is time consuming, complex, and it also requires expensive equipment. The second method is based on using the RayMan, ENVI-met and SOLWEIG computational models often employed in urban climatological research. The present research deals with the comparison of MRT data obtained by measurement and computational simulation for a dense city quarter of Lisbon: Campo de Ourique. The measurements were carried out during four summer days in 2006, in a park and in the surrounding canyon streets. An overall good fit can be observed between the simulated and the measured MRT values, however significant punctual differences can occur.
