*3.2.1 Daylighting*

For daylighting analysis, the Radiance program was used through the Daysim/ Honeybee graphic interface, and Grasshopper/Rhinocerous3D plugin (**Figure 10**). To evaluate the performance of daylighting, 2 metrics were used: DA (Daylight Autonomy – or Natural Lighting Autonomy) considering 300 lux, and UDI (Useful Daylight Illuminance) considering a maximum of 2000 lux. In both cases, the measurement plane considers the height of the work plane at 80 cm in relation to the floor and the mesh of stitches distributed every 50 cm. In terms of the availability of natural light during the period of occupation of the building, the interval from 8 am to 6 pm was considered valid, during all 12 months of the year.
