ABSTRACT

Successful daylight from the side begins with maintaining a relationship between window head height and room section depth. There are two primary strategies to address this condition. First, section depths can be kept narrow to ensure both daylight penetration and spatial luminous uniformity. Alternatively, additional sources of daylight are added to provide supplemental illumination. Additional daylight sources are provided in the form of vertical fenestration on multiple sidewalls. Typical ambient office lighting criteria range from 300 to 400 lux, and 300 lux was selected as one of the daylighting design criteria examined herein. The daylight reaches the first 15' from the windows, but blinds would likely be drawn closed to reduce glare from contrast. Windows comprising 20" window wall ratio are added to one long wall, dramatically reducing the perception of glare. White walls and low partitions support the perception of brightness, and deep window reveals and building self-shading minimize solar penetration and reduce the potential for glare.
