The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) convened its 2014 Annual Conference from June 28 to July 2 at the Sheraton Seattle and the Washington State Convention Center in Seattle, WA. A track devoted to Ground Source Heat Pumps State of the Art: Design, Performance and Research addressed those topics in all applications

The track attracted researchers from around the world to discuss technology advances and to learn about the latest research and state-of-the-art practices. The track was developed by ASHRAE, the Geothermal Exchange Organization (GEO), the National Ground Water Association (NGWA), and the International Ground Source Heat Pump Association (IGSHPA). GEO President and CEO Doug Dougherty (left) provided the keynote presentation for the track, Market Barriers and Market Drivers for the U.S. Geothermal Heat Pump Industry. “It was great,” he said. “Every session room was filled to capacity with scores of participants eager to learn more about several game-changing geothermal technology developments presented during the conference.”

“Our goal was to help practicing engineers understand where the industry began, where it stands currently, and where it is headed,” said chief track organizer Dr. Jeff Spitler, Regents Professor, Building and Environmental Thermal Systems Department at Oklahoma State University. “During the ASHRAE Geothermal Technical Committee meeting, a fourth of participants said they attended the conference solely for the geothermal track,” said GEO Member and track organizer Lisa Meline (Meline Engineering – Sacramento, CA). The track included 42 presentations on:

  • Geothermal Project Site Assessment
  • The Updated ASHRAE GSHP ‘Blue Book’
  • Ground Source Heat Pump System Case Studies
  • GHP Project Contract Administration
  • Historical Perspectives and Monitoring of GHP Systems
  • Simulation and Modeling of Ground Heat Exchangers
  • Ground Source Systems Commissioning and Closeout
  • Central Plant GCHP Systems
  • Optimization of Ground Coupled Heat Exchangers
