Geothermal Heat Pump and Energy Recovery Applications
ASHRAE Technical Committee 6.8

Upcoming Geothermal Educational Meetings / Seminars in Atlanta


Sunday, January 13, 8:00 AM - 9:00 AM

Seminar 2 Location: Georgia World Congress Center, 3rd Floor, Building A, Room A301

Steps toward Net Zero for the Marine Corps Logistics Base at Albany GA
Program Track: Renewables and Natural Systems

The Marine Base at Albany, GA has been moving toward the aspect of Net Zero operations in steps of varied methods and this seminar is a recap of some of those elements. Step 1 is the addition of Sustainable Power by installation of a 31 MW PV Facility in cooperation with Georgia Power. Step 2 is the application of BTES system and application of Ground Source Heat Pump technology to improve energy efficiency in replacement of HVAC at the Base. Step 3 is the use of Retro Commissioning to review existing facility operations and make modifications for minimizing energy consumption.

Ground Source Heat Pumps: You Can't Always Get What You Want

  • Program Track: Common System Issues and Misapplications

Chair:  Michael Kuk, CERx Solutions, LLC, Oswego, IL, USA                                                                                                  .

Technical Committee: 6.8 Geothermal Heat Pump and Energy Recovery Application

    • Summary: This session presents multiple examples of how you (the designer) don't get what you always want. Just because a system is designed well or with good intention does not mean that it gets built or operated the way you intended. The seminar also presents examples of projects that didn't meet the design intent because the system wasn't initially commissioned, or properly constructed, operated or maintained. Or they didn't follow sound engineering principles. Examples of how to avoid these pitfalls are presented, along with good solutions and good examples.


      1. Well You Just Might Find (Through Commissioning) That You Didn’t Get What You Need

      Presenting Author: Michael Kuk, CERx Solutions, LLC, Oswego, IL, USA

      This presentation provides an overview of a retro-commissioning project performed by Mr. Kuk for a 10 year old middle school in Illinois. This school was designed to be ultra-energy efficient with a pond-loop based water-loop heat pump system, energy recovery DOAS systems, demand control ventilation system, and variable flow systems. Yet it scored only a 1 on the Energy Star Rating System and had serious operational issues. A very long list of issues was identified, but the root cause was that the building was not initially commissioned, was not built and operated per the design intent, and it was not properly operated or maintained thereafter. This presentation will present the findings, recommendations, and fixes made.

      2. But if You Try… You Get What You Need

      Presenting Author: Stephen Kavanaugh, University of Alabama, Northpoint, AL, USA

      This presentation provides results for six non-residential ground source heat pumps (GSHP) systems. Two systems are located in the mid-Atlantic, two in the coastal South, and two in the mid-West. One system in each location has performed well while the other has performed below expectations. Performance metrics are demand, energy use, Energy Star rating and occupant satisfaction. Summary of equipment and ground loop specifications are provided. The presentation will close with summary results for a school district with 25+ years of excellent GSHP experience.

      3. Burying Mistakes
      Presenting Author: Lisa Meline, P.E., Meline Engineering Corporation, Sacramento, CA, USA

      This presentation is a cautionary tale about what happens with geothermal system designers trust but don’t verify. A failure analysis of the system in this presentation points to a design that was sound in principle but was not properly seen during installation. The result was an expensive repair to the building owner that could have been avoided.



      Pairing Geothermal and Hydronic Systems in Residential Buildings

      Monday, January 14, 11:00 AM – 12:00 PM

      Seminar 36 Location: Georgia World Congress Center, 3rd Floor, Building B, Room B313b

      Program Track: Systems and Equipment
      This seminar provides design tools and tips for residential buildings utilizing a ground-source heat pump paired with hydronic heating and cooling system. A cutting-edge design example for a home currently constructed in Northern California is the basis of the seminar. Presenters will review the load calculations and sizing of the ground-loop heat exchanger and hydronic piping design. Combining sound piping strategies, proper air management, and latest pump technology with simple design and control approaches can improve overall system efficiencies. References to applicable sections of ASHRAE 90.2 will be included in the design considerations.
