Daylighting in highly obstructed buildings: street

Daylighting in buildings facing traditional streets is usually uneven . Upper floors receive most light and look excessively bright, while the lower parts of the buildings may appear gloomy. This paper presen ts two strategies for façade design that ensures balanced daylighting . Both strategies were studied on the model under the overcast sky co nditions. The parameters influencing daylight levels in a street are discussed and a design tool, for estimation of the window area in roo ms facing a street, is presented.
