Sunnybrook Hospital H-wing lighting control upgrade

Sunnybrook Hospital H-wing lighting control upgrade

Objective: Reduce energy consomption during nights and weekends 

Communication links between floors and between cricuits are done through wireless RF interfaces INT-XB. Less than 20 feet of low-voltage wire were added.

For circuits not already design for security lighting at night, relays were installed in 3 out of 4 fixture solving the problem. 

No rewiring was necessary.

None intrusive installation, with most relays being installed inside the fluorescent fixture as easily as replacing a ballast.

  Scenario:

•Scheduling and management from a server located in another building, lights are automatically turned off every night, on weekends and during hollidays by the scheduler. An overide switch is easily acessible for maintenance personnel.

•Working in ceiling or cutting into walls would have required installation of tents to prevent contamination

•Intense Circulation in corridors was not an issue.

•H wing , 6 floors, about 90 relays, interfaces and server installed and commissioned in less than 5 days
