Details

Eight calculation planes 0.8 m above each tier. Two types of LED luminaires (Ra ≥ 80): recessed round downlights set into the acoustic ceiling relief, suspended linear luminaires where those fall short. Three studies: daylight, artificial and combined lighting, with daylight sensors and dimming.
