Lighting and HVAC Control
Technical Discussion

Integrated Building Systems
Integrated building systems allow for the modification of an environment independently of environmental choices made by others
Environment consists of both lighting and temperature control
Integrated means HVAC & Lighting have a common control system and front end.

Meaning …
Mechanical zones integrated with lighting & day lighting zones are grouped together to meet client’s needs.
Modular lighting & HVAC control systems.
Modular ‘plug and play’ wiring connections
Central performance monitoring for energy.
Management and scheduled maintenance with automatic feed-back of activities.

Why Integrated Controls?
Provides sensible and efficient use of environmental systems
Savings of 50 to 75 percent by use of dimming ballasts and daylight harvesting and an estimated 10-15% HVAC savings when providing zone (air jets) control has been documented in pilot installations at PWGSC
Connecting integrated systems to a priority energy demand metering control would permit the building operator to minimize energy costs by buying energy at the best price in the upcoming deregulated energy market
