2023 Conference Proceedings | International Ground Source Heat Pump Association

Back to Annual Conference Proceedings Main Page

The 2023 IGSHPA Annual Conference in Las Vegas, Nevada on December 5 to 7 was a great success!

The partnership with NGWA (National Ground Water Association) provided attendees with even more exhibits to visit and gave NGWA attendees the opportunity to attend IGSHPA workshops, as well as discuss geothermal opportunities with exhibitors in the IGSHPA pavilion. This was the 3rd annual conference of the new independent IGSHPA organization.

Below are links to the presentations from the conference^1,2
