Spec Tuesday: EN 17037, decoded.
When a daylighting assessment says a project complies with EN 17037, this is what actually changes:
➡️ More usable natural daylight throughout occupied spaces
➡️ Better occupant wellbeing, visual comfort, and connection to the outdoors
➡️ Reduced reliance on artificial lighting during daylight hours
EN 17037 evaluates four key aspects of daylight design:
☀️ Daylight provision
👀 View out
🌤️ Access to sunlight
🕶️ Protection from glare
For roof glazing, compliance often means larger daylit areas, improved daylight distribution, and stronger evidence for planning and sustainability targets.
Sunsquare SkyView systems are designed to maximise daylight performance.
