SCHOOLS’ ENERGY CONSUMPTION,
REDUCED!
CASE STUDY
PROJECT NAME: Renton School District
TYPE OF FACILITY: Education Facilities
LOCATION: Renton, Washington
ENERGY SAVINGS
Before the upgrade project, the annual energy
consumption was 215,647 kWh. After the Hubbell
Lighting exterior LED fixtures were installed, energy
consumption decreased to 39,027 kWh annually.
That equates to an 82% reduction in energy
consumption, saving approximately $15,000
annually at today’s electrical rates. Along with
substantial energy savings, maintenance savings
has been realized in that the LED’s have a rated life
of 50,000 hours compared to a rated life of 2,500
hours for the old fixtures.
PROJECT CHALLENGE
Located southeast of Seattle, Renton School District
covers 35 square miles, with 28 facilities,
comprised of 2.4 million square feet, serving
15,000 students. When the District Energy
Management Office began looking for ways to
reduce energy costs at their schools, they realized
that upgrading to efficient LED lighting offered an
ideal solution. The existing exterior lighting was
beyond its useful life and lighting levels were
grossly inadequate. The outdated and inefficient
exterior wall packs were metal halide fixtures with
wattage ranging from 90 to 400 watts. As a result
of the heat of the high wattage HID lamps, the
fixtures’ polycarbon lenses became discolored and
compromised the light output.
HUBBELL LIGHTING’S SOLUTION
After the school district completed a yearlong
pilot project where they installed and tested the
LED products of several national companies, 437
of Hubbell Lighting’s Laredo LED Architectural
Wallpacks were installed on every facility in
the district.

PROJECT BENEFITS
Hubbell Lighting’s Laredo LED Architectural
Wallpacks provide low installation costs with little
or no maintenance and are ideal for academic
applications. The “Quick Mount” adapter allows
one person installation without ever opening the
fixture and the fixtures feature 50,000 hour rated
life with a minimum 70% lumen maintenance.
From the Customer
We had replaced the old HID fixtures in one
our middle schools back in 2010. Once we
realized the energy and maintenance
savings, we knew a district wide upgrade
would provide an impressive return on
investment. We installed over 400 of the
Hubbell Lighting exterior fixtures and to
date, they have exceeded our performance
expectations. We were able to purchase
three different units (12.6W, 20.6W and
32/71W bi-level) two of which were available
in the same fixture housing; they are virtually
bullet proof, provide bright white light, are
extremely energy efficient and qualified for a
$50K utility incentive!
