PROJECT PROFILE
North Jackson Elementary School Gym
OBJECTIVE: Given Jackson County Board of Education budget restrictions, provide a highly cost-effective air conditioning
solution for the North Jackson Elementary multi-use gymnasium, which had never been air conditioned.
The North Jackson Elementary School Gym is a typical metal
framed structure that houses a full-size maple hardwood basketball
court as well as offices and restrooms. In addition to daily
PE classes, most school functions (assemblies, graduations and
general meetings) are also held in the space.
200-amp single phase electric service to three phase in order to
meet the needs of a 30-ton package unit. Necessary ductwork
was estimated at another $15,000 and associated equipment
costs were close to $22,000. At a price tag of nearly $52,000,
the project was not likely to gain Board of Education approval.
A traditional air conditioning conversion for this space would involve
a package unit on the ground and fabricated ductwork running
up the side of the building, through the gymnasium wall, and
continued down the center of the gym. The primary issue with this
standard application is associated cost.
The school estimated costs of nearly $15,000 to convert the
Josh Patton, the HVAC Foreman for Jackson County Board of Education,
had recent experience with using LG duct-free products
during a cafeteria conversion he had completed in June 2011.
Josh used LG Multi-F products to provide supplemental cooling
in the cafeteria space as a cost-effective alternative to adding
ductwork. The school district was impressed with the performance
and efficiency of LG’s duct-free solution.

OBJECTIVE: Given Jackson County Board of Education budget restrictions, provide a highly cost-effective air conditioning
solution for the North Jackson Elementary multi-use gymnasium, which had never been air conditioned.
In partnership with the local LG Representative and Wholesaler,
Josh proposed a design that met the cooling requirements based
on load calculations for the gymnasium space, while also working
within Board of Education budget restrictions. The resulting
system included 8 indoor units around the perimeter of the gym
discharging air towards the center, and 3 ceiling cassettes in
the center of the gym discharging air in a 4-way pattern. The 12
indoor units and 7 outdoor units operate independently of each
other and provide load matching capability far beyond a single
system utilizing a single thermostat.
we could maintain 78-80 degrees, and can’t believe how well
the system performed under these conditions,” said Josh Patton,
HVAC Foreman for Jackson County Board of Education.
Using the LG technology not only enabled them to stay within
budget, it allowed them to exceed their estimates for conversion.
Georgia Power provided a rebate for using the high-efficiency
systems to further offset the costs. “I saved more than $10,000
by using the LG Systems on this job before we even factor in
operating savings,” added Josh.
The systems were installed on the existing electric
service, effectively eliminating the costs associated
with an electric service upgrade. Additionally, the
Inverter Systems allowed Jackson County Schools
to remove space heaters, also eliminating the gas
bill for heating the gym in the winter.
During a graduation ceremony in May 2012, the
gym was able to maintain set point (68 degrees
F) with nearly 400 people present. “I had hoped
