Abstract

Daylighting continues to be a primary design strategy to reduce energy use, electrical loads and peak electrical demand in new commercial buildings. Daylighting can also account for important LEED^TM points toward certification. Daylighting office buildings greater than four or five stories, however, continues to be a difficult design problem. This paper presents state of the art daylighting design of six recent large, multistory office buildings. The fundamental challenges remain constant across the projects: how to admit useful levels of daylight as deeply as possible and deliver a high quality visual environment with no excessive contrast or uncontrolled sun penetration, within budget and acceptable to the aesthetic criteria of architect and client. The daylighting design solution for each building is discussed in terms of building massing, the window wall design and integration with structural and mechanical designs.
