ResMed Corporate Headquarters houses 230,000 sf of offices in San Diego for an international corporation. Loisos + Ubbelohde developed a sophisticated energy-saving strategy that coupled building performance with electric lighting, daylighting, and a high-performance envelope design. At the building entry, the lobby backdrop is a programmed light sculpture backlit by an array of computer-controlled LED’s—creating a bold wash of color that shifts subtly throughout the day and through the seasons. The changing colors are reflected in the Chain of Ether, a wind-activated sculpture by Ned Kahn that is continuous from inside to out. Indirectly lit clouds dance below the ceiling and continue through the double-height lobby that engages the cafe and lounge areas.

L+U designed a custom light fixture for the corporation’s boardroom echoing design themes used throughout with multiple scenes for flexibility and visual comfort. The fixture’s optics and efficacy were analyzed with the use of multiple renderings in Radiance, examining glare ratios, illumination levels, and color temperatures. Regular conference rooms feature multiple downlight sources for a range of scenes along with continuity with the circulation lighting. Solar orientation and daylight penetration were analyzed throughout the building to determine detailed lighting controls and an automated mechanized shade protocol that greatly reduce the building’s energy demand and mitigate solar heat gain. Large open office spaces benefit from daylighting coordinated with a task-ambient approach, using uplighting for general illumination with low-wattage LED task lights on the desks for individual control.
