Reduce Energy Usage, Improve Comfort

A geothermal heat pump, or ground source heat pump (GSHP), is a central heating and cooling system that transfers heat to or from the ground. It uses the earth as both a heat source (in the winter) and a heat sink (in the summer). The CMS team developed geothermal systems for each of the existing systems at seven USACE Tulsa office locations to reduce energy costs and improve air quality at these facilities.


CMS replaced outdated boiler with three energy-saving, high efficiency boilers. Work also included repairs to the electrical distribution, lighting, and fire detection systems; installation of additional power and communications wiring; and renovations to interior finishes. The project also included lead abatement, removal of asbestos containing material, and removal of equipment containing mercury and PCBs.
