Although the OCCC’s other major building, the North/South building, was completed in 2003, the West building was built in four phases between 1986 and 1996. CD+M Lighting Design Group was brought in to make recommendations on the West Building’s aging lighting control system.
Crediting the maintenance program set up by OCCC technical service supervisor Greg Cyr and his technical staff, CD+M Lighting Design found that the major components of the lighting system were still in good shape, and that there was no need to undergo the costly and time-consuming process of replacing the entire system. CD+M was also able to reuse existing wiring for the 400 new wall stations that would be part of the upgrade.
For the “front end” controls, CD+M used a Lutron Grafik 7000 centralized lighting control system, which allows for BACnet, DMX512, RS232 and contact closures control interfaces for integration with BMS, fire alarm, occupant sensors and other building management and automation systems.
The OCCC has the ability to divide large meeting rooms and exhibit halls into smaller spaces through the use of movable partition wall panels. The Lutron Grafik 7000 system can reconfigure the lighting zones to accommodate these partitioned spaces, while also providing individual lighting controls.
The system runs with built-in astronomical time settings, and a series of OFF presets have been programmed to sweep through the facility after hours to save energy.
Although CD+M replaced the older control electronics of the existing Strand Lighting (66) CD80 SV dimmer racks and (23) DE90 dimmer cabinets with Johnson Systems’ CD3000 & DE90 retrofit control electronics, it didn’t replace all the dimmer racks and cabinets. By reusing existing equipment, CD+M estimates that the upgrade costs could be kept to only about 15 percent of what it would have cost to replace everything.
The switch provided CD+M with a new controls package that includes a power saving “stand-by” mode that complies with the International Energy Agency’s “One Watt Initiative.” CD+M also estimated that this upgrade, when compared to the cost of replacing all the dimmer racks and cabinets, could be achieved at
Murphy Lighting Systems joined the project, providing their experience in integration along with a familiarity with the OCCC West Building system. Their scope of work included the inspection, cleaning, repair of the existing dimmer racks and the installation of the new Johnson Systems’ CD3000 & DE90 retrofit control modules.
One of our key goals of the OCCC West Building upgrade was to provide the convention center’s technical staff with the flexibility to quickly respond to any lighting issues from anywhere in the 4 million square foot West Building, or from offsite. This was achieved via Dialogic JCT media telephony interface card installed in the main lighting system computer local in the facility’s server room.
Now the OCCC technical staffs have the ability to control the lighting system at any time through the use of four-digit telephone codes, untethered from the main lighting control system computer.
For more advance setups, the staff can also utilize a laptop equipped with the Lutron Control IT web-browser based software to quickly reconfigure the lighting to suit the client’s unique lighting requirements in any of the meeting rooms or exhibit halls.
OCCC can also provide portable 9-button preset stations to give their clients the ability to create and activate different lighting presets during their event.
The new system includes a fiber-optic backbone between major components and an extensive Ethernet network. To satisfy the OCCC network standards & compliance issues, OCCC Database Administrator, Rick LeBlanc, supervised the new network installation.
Those involved in the project included Greg Cyr, OCCC technical service supervisor; Brian Kennedy, OCCC project manager; Rick LeBlanc, OCCC database administrator; Max Brito, Rhodes+Brito Architects; Jim Kelly, Potential Electric project manager; Randy Brown, Lutron project manager; Tom Page, Lutron field service engineer; Shaun Johnson, Johnson Systems Inc. president; Chris Murphy, Murphy Lighting Systems president; and Richard Hoyes, CD+M Lighting Design Group.
