HEAT STRESS IN BERLIN (GERMANY)

Three sample sites with different urban structures were chosen for studies of thermal sensation during the heat wave year 2003 in the City of Berlin. Meteorological, urban morphology and personal data were used for the modelling of the thermal index physiological equivalent temperature and the mean radiant temperature using the program RayMan. During summer 2003 air temperature values were higher than the average of the years 1998-2004, with summer days and hot days already in June. Analyses of the Physiological Equivalent Temperature show clear differences between the different sites due to varying shading and radiation effects following from building structure and vegetation
