Clark County (KY) School is
Awarded 'Center of Excellence' for Sustainability from SEMCO.
Geothermal and chilled beam
design makes George Rogers Clark H.S., Lexington, Ky., one of
North America's most sustainable schools.
Kentucky's Clark County Public Schools
(CCPS) received the Center of Excellence award Aug. 1, from SEMCO
LLC, Columbia, Mo., for a sustainable and energy cost-reducing green
design at the new George Rogers Clark High School, Lexington, Ky.
The 300,000-square foot, Winchester, Ky., high school is one of
North America's most sustainable school building and uses a
geothermal-based chilled water loop combined with SEMCO chilled
beams and dedicated outdoor air systems (DOAS) for its innovative
heating, ventilation and air conditioning (HVAC) system. The
state-of-the-art building is recording 35-percent less monthly
utility costs versus the 30-percent smaller conventional high school
The school's advanced indoor air
quality (IAQ) helped contribute to a district-wide 1.5-percent
attendance increase last year which earned a $200,000
government-awarded attendance incentive. Furthermore, the school is
bigger than most high schools nationwide and ranks as one of
Kentucky's largest, but is recording a 31.9-k/BTU energy use index (EUI)
which is significantly less than the 68-k/BTU EUI of an average
sized U.S. school.

Christy and the building's architect Ron Murrell Jr., AIA,
principal, RossTarrant Architects, Lexington, Ky., received the
inaugural award on behalf of Clark County Public Schools from
SEMCO's Director of Sales, Tom Rice, at SEMCO's Columbia,
Mo.-based Research & Development Laboratory.
Christy, a former CCPS director of operations who oversaw the
GRCHS design, now plans retrofitting an older district school
and its HVAC. Chilled beams will be specified again, but because
of the facility's circa 1970's thinly-insulated envelope,
potential condensation will be proactively controlled with
recently-developed chilled beam pump modules, which Christy
reviewed with other technology at SEMCO's 100,000-square-foot
"Paul Christy is a rare breed of school superintendent who
searches for and understands cutting-edge HVAC technology,
because he realizes it not only cuts school operating expenses
and taxpayer costs in the long run, but also provides a better
learning IAQ environment for students and teachers," said Rice.
Since its founding in 1963 as a sheet metal fabrication company with
five employees, SEMCO has built a reputation as a worldwide product
innovator in the science of air movement, noise abatement, energy
efficiency and indoor air quality with more than 200 employees and
more than 200 manufacturer's representatives. Major product lines
include spiral metal HVAC duct, energy recovery equipment, chilled
beams, and acoustics equipment. SEMCO is a Fläkt Woods company based
in Columbia, Mo. SEMCO operates three manufacturing facilities in
Morrilton, Ark., Petit Jean, Ark., and Roanoke, Va. SEMCO also
operates an ASHRAE 84-compliant research and development facility
dedicated to the innovation of new products for the 21st Century and
