description	The use of daylight in indoor environments contributes to reduce artificial lighting. The objective of this research is to evaluate the daylight performance in kitchen and laundry environments of multifamily residential buildings with different spatial configurations in the city of Porto Alegre - RS, by using NBR 15575-2013 standard criteria and the Useful Daylight Illuminance (UDI) evaluation metric. The objects of study were divided into two groups: models with direct daylight in both rooms and models with indirect daylight in the kitchen. The analyses were carried out through computer simulation with DIALux software and the DIVA plug-in in for Rhinoceros. Based on the analyses performed by NBR 15575-2013 standard, only the kitchen with exterior shading devices was classified as intermediate lighting performance, and all the other environments were classified as superior performance indicating that artificial lighting is not necessary during the day. The illuminance of the central point did not coincide with the kitchen work surface, therefore, the same level of light performance on this surface was not guaranteed. The results obtained through the UDI metric indicated the prevalence of the autonomous range in the models with direct daylight and the supplementary range in the models with indirect daylight. Unlike the standard analysis, the UDI metric considers the mean of the average illuminance, covering the environments as a whole.

A utilização da luz natural contribui com a redução do uso de iluminação artificial em ambientes internos. Esta pesquisa tem como objetivo avaliar o desempenho da luz natural em ambientes de cozinha e de área de serviço de residências multifamiliares com diferentes configurações espaciais na cidade de Porto Alegre – RS, por meio dos critérios da NBR 15575-2013 e da métrica de avaliação Useful Daylight Illuminance (UDI). Os objetos de estudo foram divididos em dois grupos: modelos com iluminação natural direta para ambos os ambientes e modelos com iluminação natural indireta para a cozinha. As análises foram realizadas por meio de simulação computacional com o software DIALux e o plug-in DIVA para Rhinoceros. Com base nas análises realizadas pela NBR 15575-2013, classificou-se como desempenho lumínico intermediário apenas a cozinha com brise de proteção solar, à medida que todos os outros ambientes foram classificados como desempenho superior, indicando que o uso de iluminação artificial não se faz necessário ao longo do dia. O valor de iluminância obtido no ponto do centro geométrico não coincidiu com a bancada da pia da cozinha, assim, não se teve a garantia do mesmo nível de desempenho lumínico nessa superfície. Os resultados obtidos pela métrica UDI indicaram a prevalência do intervalo autônomo nos modelos com iluminação direta e o intervalo suplementar nos modelos com iluminação indireta. Diferentemente das análises por meio da norma, a métrica UDI considera a média da iluminância do recinto, abrangendo os ambientes como um todo.
