COVER STORY

Daylighting

Elise M. Strobach and Svetlana V. Boriskina

In a quest for energy savings, occupant comfort and aesthetic appeal, by drawing on examples both ancient and modern, architectural designers are using the basic principles of optics to bring sunlight deep into building interiors.
