Specular Reflectors

Reflectors are used in bring daylight into a building. Different shapes will vary the way light is reflected within the building. Reflectors are generally used to reflect light through clerestories into a structure.

Ventura Coastal Corporation's Administration Building in Ventura California designed by Scott Ellinwood uses natural daylighting techniques and won the Owens-Corning Fiberglass Energy Conservation Award in the Commercial Built Category in 1983. Ellinwood has also received three honor awards from the American Institute of Architects (AIA) and he is also a LEED certified Professional.

Section Description

As we can see from the section, Ellinwood uses many different methods to bring indirect natural light into the building, direct lighting can be invasive to one's personal space and result in additional cooling costs. North facing windows (north is to the left) and a northern clerestory provides indirect lighting into the interior. The southern windows are shaded to block out direct sunlight (right) creating only indirect lighting in the interior using specular reflectors. The angled ceiling helps to direct the light deep within the building.
