COLO CAPITAL BLDG ADDS GEOTHERMAL HEATING-COOLING

CO State Capitol Is First To Boast Geothermal Heating & Cooling

“Colorado will be the first state capitol in the country to power all heating and cooling with geothermal energy…The open-loop geothermal system taps into the Arapahoe Aquifer, which sits more than 850 feet underground and is a consistent 65 degrees. This system, recently brought online, is expected to save the 119 year-old building $100,000 in heating and cooling costs in the first year alone…To install the system, Chevron Energy Solutions drilled an 865-foot well under the state capitol, and ran a pipe into the Arapahoe aquifers below. Unlike a closed-loop system, an open-loop geothermal system is connected directly to a ground water source such as a well or pond and directly pumps the water into a building to the pump unit where it is used for heating and cooling. Open loop systems require access to a substantial water source, but are more cost effective…” click here for more
