International Ground Source Heat Pump Association

Established in 1987, the International Ground Source Heat Pump Association (IGSHPA) is a nonprofit, membership-based organization that promotes geothermal heat pump technology. It was a outreach unit of the College of Engineering, Architecture and Technology (CEAT) at Oklahoma State University until 2020. In June 2020, the OSU Board of Regents voted to approve a transfer of IGSHPA, its intellectual property, and assets to the control of the Geothermal Exchange Organization (GEO).

Primary Efforts
IGSHPA is the main organization for establishing standards of practice and standards of design for Geothermal Heat Pump (GHP) systems in the US. Related organizations have been formed in other countries on four continents, including Australia, Canada, China, India, South Korea, and Sweden.

Conferences
Each year the association hosts an annual conference for people such as manufacturers, contractors, distributors, and drillers.

Standards
IGSHPA sets and revises standards for Geothermal Heat Pump (GHP) system installs based on ongoing research and field application results.
