Daylight in Architecture
Daylight is constantly changing. The other elements of architecture we have considered can be exactly determined. The architect can fix the dimensions of solids and cavities, he can designate the orientation of his building, he can specify the materials and the way they are to be treated; he can describe precisely the quantities and qualities he desires in his building before a stone has been laid. Daylight alone he cannot control. It changes from morning to evening, from day to day, both in intensity and color. How is it possible to work with such a capricious factor? How can it be utilized artistically?
