Daylight, architecture and people's health

While the evidence linking light to a plethora of health issues is plentiful, building industry and its regulatory bodies are yet to address this issue in a manner that reflects its saliency. It has been suggested that one way to cultivate support for daylighting legislation is to underscore its health effects. Though these may be long term ones, they are, nonetheless, real and should be taken into serious consideration. Many cities around the world have now zoning ordinances that legislate public access to sunlight in streets and public parks, but this legislation still doesn't go far enough to command the presence of sunlight inside people's homes and workplaces. For the most part, sunlight (or daylight) is still considered as an amenity in our living and workplaces. The question that remains unanswered is whether it is really only an amenity? This paper examines the relationship between light and human health and discusses daylighting standards in light of this relationship.
