Figure 1: Indirect lighting in this space at the Madonna Rehabilitation Hospital in Lincoln, Neb., also reduced glare of direct lighting, giving the space a softer light with heavy reliance on daylighting. Challenge: Design of a light-filled, 110-bed, 250,000-sq-ft rehabilitation hospital, which requires and is dependent on direct access to natural light to nurture a healing environment.

Solutions:

  • The lighting power density was 0.78 W/sq ft, compared to the code maximum of 1.2, which is a 35% improvement.
  • The lighting controls were designed around ASHRAE Standard 90.1-2007.
  • Patient rooms: Individual room controller with combination of 0 to 10 V dimming and switched lighting loads. Manual daylight zone control.
  • Corridors: Bi-level switching throughout all corridors. Lighting to 50% is always on, although controlled by a relay if future adjustment of the control scheme is desired, with manual control of the additional 50% output at the nurses’ stations.
  • Rehabilitation gymnasiums: Relay control for automatic-off control of lighting after hours, and low-voltage switches with the room broken up into multiple zones to allow for some lights to remain off if the entire gym is not in use.
  • Occupancy sensors, in a manual on and auto off configuration, were used in offices, work rooms, storage rooms, restrooms, etc.
