Modeling the Spectral Properties of Obtrusive Light Incident on a Window: Application to Montréal, Canada

This paper describes the use of a new obtrusive light module Illumina v2 model to estimate that may enter bedroom windows. We used following as input model: (1) sources’ flux and spectrum derived from color images taken by astronauts International Space Station (ISS), (2) an association between source angular emission, (3) per zone inventory obstacles properties lamp height. The calculates spectral irradiance incident buildings’ windows taking into account orientation street. By using information ISS image, we can classify pixels function their spectra. With same it is also possible determine upward photopic radiance for each pixel. Both serve inputs calculate on any window. having irradiance, Melatonin Suppression Index Such later be perform epidemiological studies. methodology applied city Montréal in Canada set houses’ locations. computations are made 2013 (pre-LED era).
