Daylight, Architecture And People’s Health

Abstract
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.

1 Introduction
Neither current lighting design guidelines nor the illumination standards address
health issues related to light and building occupants despite the large body of
evidence connecting light to range of health issues. Lighting standards have been
largely based on visual performance as the sole criterion for prescribing lighting
quantities (Boubekri [1]). The use of visual performance as the single criterion
for prescribing illuminance levels, concerns about energy efficiency and
consumption and improvement in lighting technologies have caused
requirements for light levels to decrease over the last fifty or sixty years (IES [2,
3]). Research indicates that electric lighting alone cannot address health needs of
the occupants. In fact, electric light may be the cause of several health problems.
If one must address the health issues, it becomes necessary to look at daylighting
