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 Marilândia, 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.

Daylighting presents an important role for high performance buildings. Currently, Building Information Modeling (BIM) has excelled in the Architecture and Engineering (A&E) industry as a collaboration and information exchange methodology that generates integrated computational models. Simulation plug-ins for BIM tools capable of performing daylighting simulations in a semi-automated way have been developed, thus presenting a more simplified simulation process and favoring the adoption of performance analysis since initial design stages; being a little explored subject. This article aims to investigate the Insight plug-in for Revit, focusing on its daylighting features. The workflow, input-output structure and results of Insight dynamic (sDA) and static (illuminance levels) daylighting metrics were analyzed, comparatively to the plug-in DIVA-for-Rhino, which simulation engines were considered validated by literature. Simulations on both software used the same model of a reference office space for the city of Belo Horizonte. Results indicate that Insight’s favors the daylighting analysis in the initial phases of the design process and allows the verification of code compliances, however determining materials optical properties presents some degree of complexity. Low sensitivity to glasses with low and medium values of light transmittance was noticed in the case study. Evidence of consideration of internal reflections of light rays (ambient bounces) close to 7 may leed to overestimated results in the case of low complexity models. This study intends to contribute to the understanding of the potentials and limitations of both analyzed tools, especially in regard to the specificities of BIM daylight simulation with Insight.

Resumom Belo Horizonte, os parâmetros urbanísticos municipais associados às características topográficas da malha urbana da cidade levaram a crer que a quantidade de luz natural admitida nos ambientes residenciais, especialmente em andares inferiores, poderia ser bastante reduzida. A proposta deste trabalho foi então analisar a admissão de luz natural em edifício residencial inserido na malha urbana da cidade sob a influência de diferentes topografias. Para isso, foram investigadas a declividade do terreno e a localização vertical da unidade residencial em quatro orientações geográficas por meio dos critérios propostos no RTQ-R e na NBR 15575-1. Para atendimento da NBR 15575-1, as iluminâncias internas foram obtidas de acordo com as partes 2 e 3 da NBR 15215 e também por simulação computacional. Verificou-se que pelo método prescritivo da NBR 15575-1 todos os ambientes atenderam aos limites para desempenho mínimo. Já por simulação, de 6% a 9% dos valores não atenderam a esses limites. A diferenciação em relação à topografia e à localização vertical da unidade foi notada mais significativamente na avaliação feita de acordo com o RTQ-R. Os resultados obtidos neste caso indicaram que apenas 19% dos ambientes situados no primeiro pavimento e 50% de todos os ambientes localizados na maior declividade atenderam aos requisitos para bonificação. Os resultados parecem indicar ainda que a legislação municipal deveria ser revisada nas situações de maiores declividades. Palavras
