1EVALUATE SAFETY: Looks aren’t everything. Make sure new fixtures eliminate high contrast areas and
provide even coverage to reduce dark spots.
2ANTICIPATE MAINTENANCE COSTS: Your utility bill doesn’t tell the whole story. Lighting fixtures also require
upkeep for labor and replacement parts.
Forecast these lifecycle expenses to calculate the total cost of ownership.
DEMANDS BY 80%
CLYDE, NORTH CAROLINA
No matter how riveting the professor is or engaged the students are, an inadequately lit college lecture hall can put a damper on education. Haywood Community College in Clyde, NC, selected its Charles Beall Auditorium for a lighting upgrade in October 2013. The 7,000-square-foot
space, which includes movable walls, was originally lit with 38
500W incandescent and 54 250W recessed metal halides.
With everything from meetings and classrooms to theater
performances held in the space, the fixtures were unable to
supply the wide range of light levels needed. Maintenance was
also a concern.
“With high ceilings, bolted seats, and a slanted floor, changing a
single bulb was a complicated and time-consuming task that often
required scaffolding,” explains Scott Lackey, lighting business
development manager with the electrical distributor Graybar.
Improve lighting performance for the various
events held in the college’s auditorium.
Cut energy consumption by 80% by using
LED luminaires and controls while improving
To avoid a total replacement, a new lighting system would need
to integrate with the existing ceiling grid, dimming system, and
other hardware components. Lackey performed a number of site
visits and energy assessments before suggesting recessed LED
products and a new control system. The design provides even
uniformity while increasing the existing footcandle average in
excess of 20%.
The project was completed over several weeks in January 2014
and has resulted in an 80% energy reduction, which amounts to
$6,000 in projected annual savings, in addition to maintenance
savings over service life. The project also secured utility incentives in excess of $10,000.
“Haywood Community College is dedicated to making our
campus as energy efficient as possible and we are doing this one
project at a time. The retrofit to LED lighting in the Charles Beall
Auditorium was a rewarding one,” says Teresa Starrs, energy manager and associate director of campus development.
“The main success of this project was finding a solution that
resolved maintenance and integration issues while delivering
energy savings,” adds Lackey. B

3TRACK PREVIOUS EXPENSES: Have two years of operating and maintenance costs available for
your old fixtures. These numbers will help
you project a true payback and validate
manufacturer performance claims after the
4MEASURE CURRENT LIGHT LEVELS: You need to quantitatively measure illumination rather than
depending on what looks pleasing to the
human eye. This will also give you an objective baseline for calculating ROI rather than
5TRY IT BEFORE YOU BUY IT: There’s no reason you can’t retrofit a portion of your lamps before committing to
a certain fixture for the entire installation.
You can also use the opportunity to make
tweaks to light levels.
6SEE SAMPLE PROJECTS: Ask your manufacturer for installations you can visit in person. It’s helpful to see real
applications before partnering with a vendor.
7READ THE FINE PRINT: Beyond energy and maintenance, look for key differences in the specifications.
These include surge protection, vibration
ratings, and warranty coverage.
