| Özet: | 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. |
