NICU Standard 27: Daylighting
At least one source of natural daylight shall be visible from all infant care areas, either from the infant cre station itself, or from an adjacent area. Where a window or skylight is provided, the following requirements shall be met:
- Exterior windows in infant areas or infant rooms shall be glazed with a maximum U value of 0.50.
- Exterior windows in infant areas or infant rooms shall be situated at least two feet (0.6 meters) from the infant bed.
- All daylighting sources shall be equipped with shading devices.
Interpretation: Windows and daylight provide important psychological benefits to staff and families in the NICU and therefore should be provided in as many spaces that adults will occupy as possible. The presence of windows and daylight is to support families and staff rather than infants, since exterior windows have not been shown to enhance infant development.
Where exterior windows are provided, they should be carefully placed to avoid direct sunlight from striking the infant, IV fluids, or monitor screens, to allow easy cleaning, and to avoid glare and heat loss. Shading devices should be easily controlled to allow flexibility at various times of day, and should either be contained within the window or easily cleanable.
