Neonatal intensive care units are a special lighting design challenge. Although natural light is highly desirable, it should be carefully planned to maximise benefits and minimise the problems associated with uncontrolled sunlight. This paper discusses the performance of different passive sunlight control strategies in a neonatal intensive care unit at the Dr. Humberto Notti Children's Hospital in Mendoza, Argentina, analysing their annual daylight behaviour through dynamic daylight simulations. The aim of this work is to optimise the use of daylight in neonatal intensive care units, considering the special lighting conditions required. Results show that, in this case study, the adequate implementation of solar control systems and the appropriate layout of the space for different uses according to surrounding building design and the characteristics of the local luminous climate can increase the useful daylight illuminance by up to 13%, while avoiding the incidence of direct sunlight at all times.
