Johnson Elementary Moves to Be More Energy Efficient

Work on Carroll ISD’s Johnson Elementary School has ramped up now that Summer break is here. Last week, we started transitioning the school from a traditional HVAC system to a Geothermal Heat Pump (GHP) system by taking energy efficiency to new heights! Using helicopters to remove the old rooftop HVAC units reduces the task from multiple days to just a few hours.

Geothermal heat pumps heat and cool buildings by concentrating the naturally existing heat contained within the earth—a clean, reliable and renewable source of energy.

If you’re a native Texan, then you’ve experienced the scorching heat of the summer, but did you know, just a few feet below the earth’s surface the ground remains at a relatively constant temperature? Depending on latitude, ground temperatures range from 45°F (7°C) to 75°F (21°C).

Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. The GHP takes advantage of this by exchanging heat with the earth through a ground heat exchanger.

Johnson Elementary Progress To Date

The REEDER team just completed Stage 1 of the Johnson Elementary project by wrapping up the new gym (which also functions as a storm shelter) as well as the addition of two new kindergarten classrooms and a maker space. Next stages include the addition of a new fourth grade wing along with the continued renovation of the existing school.

So enjoy the summer kids! We will see you in August with some “cooler” new digs! To learn more, visit www.reedergeneral.com.
