Bill Lawrence, General Manager & Director of Facilities @ The Pinnacle Marina Tower
In this case study, the original 243 fixtures in the garage and 146 fixtures in stairwells were upgraded to T-8 lamps with low watt ballasts and motion sensors mid-2009. The Board of Directors approved the Bright Ideas proposal, which was completed in September 2015. In this photo you can see the fixtures as they were, and are probably quite familiar to property and association managers.
In the photo below is the LED replacement for this type of fixture. The LEDs are panels which clip onto the existing fixture. The ballast is bypassed or removed, the “dog-ears are removed, as well as the lamps.
In the next photo, you can see in this fixture that some of the lamps begin to dim, when no motion is sensed.
In this case study, the LED supplier, Bright Ideas proposed material costs for $89,540 and installation was $22,330, for a total of $111,870. A rebate was received from SDG&E for $63,800 providing a net cost of $48,070. Electricity savings indicated a payback, after rebates in 11 months at $4,370 per month. The projected energy savings to the Association over a 20 year period, based on current rates should be $1,380,247. The Directors knew the savings may be short of projections, but felt the conversion to LEDs would still provide beneficial savings in electricity, lamp replacements and labor.
