Some common daylight integration details can be found in chapter 30
HAZARDS OF DAYLIGHT
For all of its power and charm, it is important to remember that there are distinct hazards of daylight applied improperly. Keep at the forefront of your mind the perils that can befall a space with poorly-controlled daylight contributions.
Heat Gains
Unmitigated direct sunlight generally contributes a fair amount of heat, in addition to excessive light. There are low-emissivity glasses and coatings that can transmit visible light without the heat contribution, but these are not commonplace. If you want direct sunlight, you get heat, or you make use of these expensive glazing technologies.
Glare and Contrast
Sunlight is an obvious culprit, creating light hundreds of times brighter than our brightest electric sources. As a task light, direct daylight is simply too bright. As an accent light, sunlight can still cause glare and contrast to which the human
visual system simply cannot adapt. Skylight and diffused sunlight can also present problems when not carefully considered with the material reflectances, colors, and visual criteria of a space.
Damage to Art, Fabrics and Other Materials
Sunlight and daylight contain a quantity of ultra violet radiation that will deteriorate dyes, inks, pigments and the integrity of organic materials. Glazing blocks all but a small quantity of UV radiation, but even this small quantity has damaging effects over time.
Excessive Window Light
Daylight windows are not necessarily view windows. Windows placed for clear views of the exterior environment should always be considered for the daylight that they will receive. Far too often, glazing is designed for views with no consideration for the intrusion of daylight that will result. Daylight systems should be designed independent of view windows and vice versa. Simple wall glazing can certainly serve both purposes, but careful study and consideration are necessary.
