Light as a design material
Daylight is one of the first ingredients of a healthy and regenerative space. In a Mediterranean climate, sunlight and shade coexist with unusual intensity. Good design uses available light without creating excessive glare or overheating.
European standard EN 17037 provides criteria for daylight provision, views out, exposure to sunlight and protection from glare. Measurement does not replace design judgement. It makes decisions more precise and comparable.
Measure before intervening
- Daylight provision and distribution within rooms.
- Useful daylight hours and seasonal variation.
- Glare protection and reflection control.
- Quality of views out and their relationship with context.
Passive strategies for the Mediterranean climate
Deep reveals, calibrated horizontal and vertical shading, loggias and intermediate thresholds can guide daylight and limit heat without using energy. Their effectiveness depends on orientation, geometry, room use and local conditions.
Shade is architecture too
Quality depends on more than quantity. Shadows, variation and reflection provide depth, orientation and comfort. The right balance between direct and diffuse light supports different activities through the day.
“The best project does not maximise light. It builds the right balance between energy, atmosphere and wellbeing.”

Frequently asked questions
Is EN 17037 mandatory?
It is not always a legal requirement, but it is the principal European reference for evaluating daylight in buildings.
Can it be applied to existing buildings?
Yes. Shading, new openings, reflective finishes and targeted changes can improve daylight quality.
