Daylighting Analysis: A Contribution to the Urban Planning of the City of Marilandia - ES (Brazil)

Abstract

Daylighting is one of the environmental resources that deliver quality to the built area by making it more comfortable and efficient and by promoting people's well-being, besides reducing the consumption of electrical energy. The amount of daylighting indoors is related to the construction features, whose parameters are those of the urban legislation, as well as to the location features where the building stands. This research aimed to get a better knowledge of the interference of the urban typologies of Marilandia, Espírito Santo (Brazil), in the availability of daylight in the internal environment. The methodology consisted of the identification and representation of the main typologies found in the city, or of those which might be built due to the current construction law; computer simulations of three sky patterns CIE (3, 7 and 12) using the Troplus 6 program; and the analysis of the results. Founded on this analysis, it was possible to see that the application of the current urban legislation has favored the better use of daylighting inside the constructions through the allowed front setback, which is three meters, and the number of floors allowed in each building, which is eight. As for the use of daylighting, the Typology 03 presented the best performance, making it possible to have a more comfortable environment with better energy savings potential.
