Iceland sets minimum daylight standards for new buildings

Iceland is introducing new regulations to guarantee a minimum standard of daylight in new buildings, a move aimed at enhancing the quality of residential spaces. The Icelandic Housing, Construction, and Planning Agency (HMS) has established guidelines for daylight, artificial lighting, light pollution, and views within buildings.

These provisions took effect on May 1 for construction projects based on zoning plans approved after that date. By August 1, 2027, the rules will apply to all construction projects seeking building permits. The core of these changes lies in the building regulations, which now include measurable criteria for daylight within apartments, encompassing both natural sunlight and artificial illumination.

"This is done to ensure these qualities, so we have dwellings that have some minimum daylight," explained Ólafur Árnason, HMS's director of planning and environmental assessment. Designers will be required to submit documentation proving they have met these new standards. If achieving the minimum daylight requirements is not feasible, a special exemption must be sought, with the local municipality making the final decision.

The regulations may present a challenge, particularly in densely built urban areas where shadows are common. However, Árnason noted that thoughtful design can overcome these obstacles. The initiative stems from a working group established in 2022 after industry professionals raised concerns about the lack of comprehensive daylighting standards.
