Geothermal Heat Pump and Energy Recovery Applications
ASHRAE Technical Committee 6.8

Upcoming Geothermal Educational Meetings / Seminars in Kansas City


Sunday, June 23, 8:00 AM - 9:00 AM


 Seminar 1: Commissioning and Re-Commissioning: The Process and the Practice

  1. Seminar 1 (Intermediate)

    Track: Commissioning New & Existing Buildings
    Room: 2104A

  2. Sponsor: 7.9 Building Commissioning, 6.8 Geothermal Heat Pump and Energy Recovery Applications

    Chair: William Bradford, P.E., Member, BRPH, Orlando, FL

    Commissioning is more than just following ASHRAE Standard 202 and ASHRAE Guideline 0 and 0.2; it is about forming a team that will help each other turn over a complex system to the owner. The first portion of this program illustrates the importance of teamwork when beginning the commissioning process. The second portion includes some examples of these complex systems being commissioned, primarily geothermal heat pump systems, and compares and contrasts them to simpler systems, showing the positives and negatives of each. Lessons learned and best practices are provided.

    1. Commissioning Is a Team Effort: A Roadmap to Customer Satisfaction

    David Meyers, AIA, Burns & McDonnell, St. Louis, MO

    1. Commissioning and Re-Commissioning Complex and Simple Geothermal Heat Pump Systems: Similarities, Differences and Critical Items

    Michael Kuk, OPMP, CPMP and BEAP, Member, CERx Solutions LLC, Montgomery, IL




Monday, June 24, 11:00 AM - 12:00 PM


 Seminar 37: Radiant Cooling and Heating Using Ground Source Heat Pumps

Track: Radiant Heating & Cooling

Room: 2104A

Sponsor: 6.8 Geothermal Heat Pump and Energy Recovery Applications

Chair: Michael Kuk, Member, CERx Solutions LLC, Montgomery, IL

Radiant cooling and heating systems are a natural match to ground-source heat pumps as their temperature ranges for heating and cooling are very moderate and allow highly efficient operation. The application of a high-mass radiant heat transfer system with predictive control significantly reduces peak HVAC loads and reduces energy use.

  1. Radiant Cooling/Heating and Ground Source Heat Pumps: A Great Match!

           Stephen Hamstra, P.E., HBDP, Member, Melink Solar & Geo, Cincinnati, OH

  1. Radiant Heating and Cooling with a Geothermal Open Loop System: A Case Study
  2.        Greg Tinkler, Member, Page, Houston, TX



Wednesday, June 26, 11:00 AM - 12:30 AM

Seminar 68: Ground Source Heat Pump System Design

Track: Systems & Equipment in the Built Environment

Room: 2101

Sponsor: 6.8 Geothermal Heat Pump and Energy Recovery Applications

Chair: Harrison Skye, Ph.D., Member, National Institute of Standards and Technology, Gaithersburg, MD

Ground-source heat pump (GSHP) systems can significantly reduce energy consumption compared to conventional cooling and heating systems. GSHPs also generally lower maintenance costs. However high firsts costs, and space limitations constrain the implementation of GSHPs commercial and residential buildings. This seminar presents design case studies, optimization, and use of hybrid systems to increase the energy and cost performance of GSHP systems.

  1. GSHP Design for Building Retrofits: Three Case Studies

Ed Lohrenz, GEOptimize Inc., Winnipeg, MB, Canada

  1. Optimizing Energy Conservation Measures to Reduce Geothermal Heat Exchanger Size

Brendan Hall, P.E., Member, CHA Consulting, Syracuse, NY

  1. Hybrid GSHP System Design for Two Buildings in Diverse Climates
  2. Suhasini Pyarasani, Member, Guttmann & Blaevoet Engineering, Sacremento, CA



Monday, June 24, 9:45 AM - 10:45 AM


 ASHRAE 125th Anniversary: Retrospect on Geothermal Heat Pumps and Refrigerant Properties

  1. Technical Paper Session 4 (Basic)

    Track: Fundamentals and Applications

  2. Room: 2203

    Sponsor: Historical Committee

    Chair: Jeff Haberl, Ph.D., Fellow ASHRAE, Texas A & M University, College Station, TX

    This session explores the pivotal waypoints in the development of the industry over the past 70 years. It also presents examples of installations, and provides best practices for ground source heat pump designs which are one of the best pathways to achieving net-zero energy buildings and homes. This session reviews the chronological variations in handbooks published from 1981 to 2017 and the properties of refrigerants published in the handbooks over time.

    1. Geothermal Heat Pumps: Simply Efficient (KC-19-010)

    Lisa Meline, P.E., Meline Engineering Corporation, Sacramento, CA and
    Stephen Kavanaugh, 
    University of Alabama, Tuscaloosa, AL

    1. Chronological Variations in ASHRAE Handbook Refrigerant Thermodynamic and Transport Properties from 1981 to 2017 (KC-19-011)

    Paul Nagy and Michael Pate, Ph.D., Life Member, Texas A&M University, College Station, TX





Wednesday, June 26, 8:00 AM - 9:30 AM


 Ground Source Heat Pumps and Novel Geothermal Systems

  1. Conference Paper Session 17 (Intermediate)

    Track: Radiant Heating & Cooling/Research Summit

    Room: 2203

  2. Chair: Kashif Nawaz, Ph.D., Associate Member, Oak Ridge National Laboratory, Oak Ridge, TN

    It is well known that ground source heat pump systems have the potential for significant energy savings and have demonstrated superior performance compared to conventional HVAC systems. The first three talks focus on improving ground source and hybrid heat pumps. The last two talks consider the role of geothermal energy on geothermal desiccant wheels and air conditioners.

    1. Long-Term Monitoring and Simulation of a Vertical Closed-Loop Ground Source Heat Pump System Used in the Cold Climate of the U.S. (KC-19-C027)

    Rui Miao, Student Member and Yao Yu, Ph.D., BEMP and BEAP, Associate Member, North Dakota State University, Fargo, ND
