| This study investigated a simple method for estimating radiation received by a person. The site is a typical urban street located in Guelph, Ontario, Canada. The radiation in the 13 locations in August, 2002, was measured 3 times a day: morning, noon and afternoon; in 3 categories: sunny locations, locations shaded by buildings and trees.; To find a simple method, directionally incoming radiation values were measured and compared to the proportion of each direction. Each direction had certain proportions of shortwave and longwave radiation over time periods.; To estimate an amount of radiation, Campbell & Norman's (1998) and Brown & Gillespie's (1986) models were used with view factors defined by fish-eye lens photographs, and the enhanced radiation models were developed and tested.; The radiation received by a person with Underwood & Ward's (1966) and Fanger's (1970) models was ergonomically analyzed. The differentials between the smallest and largest one were approximately 50W in sunny locations, 17W in locations shaded by buildings, and 18W in the morning and 29W in the afternoon in locations shaded by trees. |
