Kentucky school using ground source for HVAC

The US state of Kentucky’s Clark County Public Schools (CCPS) have installed a geothermal-based chilled water loop combined with chilled beams and dedicated outdoor air systems (DOAS) for its heating, ventilation and air conditioning (HVAC) system.

The new 300,000-square foot George Rogers Clark High School, in Lexington, says it is recording 35% lower monthly utility costs, versus the 30% smaller high school it replaced.

HVAC and services company SEMCO (pictured) supplied the beams and system.

Superintendent Paul Christy, who oversaw the design, now plans retrofitting an older district school and its HVAC system. Chilled beams will be specified again, but because of the facility’s 1970s thinly-insulated envelope, potential condensation will be proactively controlled with recently-developed chilled beam pump modules, a statement says.
