Geothermal Tapped for 2 Downtown Tulsa Buildings

August 17, 2015 By Linda Hardesty

Beneath an urban reuse area in downtown Tulsa, Oklahoma, known as Guthrie Green, a system of geothermal pipes provide cooling for two nearby buildings.

A field of 120 500-foot geothermal boreholes were drilled in Guthrie Green prior to the construction of the Tulsa Paper Company building and the Hardesty Arts Center building. The field ties into a hybrid system of geothermal heat pumps and a ground-mounted cooling tower that serve as the main mechanical systems for the buildings, according to an article in HPAC Engineering.

The geothermal-borehole field, which is organized into 15 operating circuits, provides 600 tons of heating and cooling to both buildings, with the capability of reducing heating and cooling costs by about 60 percent, says the article.

The Tulsa Paper Company building has 15 geothermal-heat-pump systems from ClimateMaster, and the Hardesty Visual Arts Center has 59 ClimateMaster geothermal heat pumps.
