8:00am      Water Side Problem Solving

Speaker:          Tom Wyer, Geo-Flo Corporation

Abstract:         Installing contractors, service technicians, and system designers commonly face problems with the water side of geothermal systems such as low flow rates, insufficient freeze protection, and unknown loop details on jobs they inherit.  This session will focus on core concepts that will allow you to better understand the water side of geothermal systems which will help you to troubleshoot and retrofit existing systems.  The format will feature live problem solving using free online tools to teach you to answer questions such as “my flow rate is too low; will adding a second pump achieve my required flow rate?”, “I’m replacing a heat pump with one that has a higher head loss; will my current flow center work?”, and “my antifreeze level is too low; how much more do I add?”.

9:00am     Resiliency Inherent In District GSHP systems

Speaker:         Greg Wolfson, EcoSmart Solution

Abstract:         Climate change has significantly increased the frequency and magnitude of severe environmental events like
fires, tropical storms, flooding and polar vortexes. These severe weather conditions often materially degrade the operational performance of renewable energy systems. In contrast, geothermal exchange systems supporting GSHPs by their subterranean design are protected from harsh environmental conditions. One such system installed at Whisper Valley in Austin Texas withstood the 100 year polar vortex, URI, in 2021. This presentation will explore the attributes of district GSHP systems that enable a broad spectrum of severe weather resiliency and the empirical performance of the EcoSmart GeoGrid during that extreme weather event in February of 2021.

9:00am     The Importance of Treating Ground Loop Fluid for Long-term Reliability

Speaker:        Dan Slater, Fernox

Abstract:        According to the U.S. Environmental Protection Agency (EPA), Ground Source Heat Pump (GSHP) systems are the most energy-efficient, environmentally clean, and cost-effective systems for heating and cooling buildings. To protect the long-term investment of the system, and ensure low maintenance of the heat pumps and pumps/circulators, the loop fluid must be treated with the proper inhibitors, even if the system does not need antifreeze. This presentation will provide practical guidelines for ensuring that the loop fluid will not cause premature corrosion, scaling, and ultimately heat pump and pump/circulator failures.

1:15pm      The Value of the Institutional Market & why it should be a target market

Speaker:          Jack DiEnna, GEO-NII

Abstract:         Geothermal technology is finally being recognized as a valued asset by the Federal market because of the modification of the definition of renewable energy to include thermal energy and changing the verbiage from generated to produced. This along with the “Climate Change” narrative should have opened the flood gates for this technology but we are still having to fight the lack of awareness for not only the technology but more importantly the benefits that these systems bring to the table. This session will point out the magnitude of the institutional market and the steps that can and should be taken by the various members of our industry to promote the adoption of GHPs. I will show how this initiative will not only increase awareness of this technology but also support greater adoption by the residential sector, The session will also touch on subliminal marketing and marketing to the various Federal clients. The session will address the marketing tactics that can be adopted to capture clients and the need to document the success of the project and the technology.

2:15pm      Elimination of Water Consumption in Data Centers

Speaker:          Jay Egg, Egg Geothermal

Abstract:         With the growth of our digital age, and the migration of data centers away from city centers, hyperscale data centers are being constructed in areas where land is less expensive, and renewable energy is potentially more abundant and locally sourced. A hyperscale data center rated at 100 megawatts may consume a million gallons of fresh water each day through its cooling tower operations. This presents an incredible opportunity to employ geothermal exchange, eliminating the cooling towers, recovering the heat, and saving precious fresh water.

9:00am      Plastic Piping Materials for Ground Source Geothermal Systems

Speaker:          Lance MacNevin, Plastics Pipe Institute (PPI)

Abstract:         The piping material is critical to the overall success of the ground-coupled heat exchanger piping system (i.e., the ground loop). It must provide corrosion resistance, chemical resistance, flexibility, impact resistance, resistance to slow crack growth, long-term hydrostatic strength (pressure capability), and temperature resistance. In addition, the ground loop heat exchanger material must provide suitable heat transfer capabilities. This course explains the four types of plastic piping materials used for ground source geothermal systems, and how these materials can be used to construct reliable ground loop piping systems. Detailed explanations of the capabilities of these materials will be provided, including reference to ASTM and CSA piping standards and material specifications. The typical applications of each of these materials will be described. The sustainability benefits of plastic piping systems will also be discussed.

11:15am    Importing drilling innovation from Sweden

Speaker:          Kathleen Hannun (Co-presenter: Ryan Malleta), Dandelion Energy

Abstract:         In Sweden, residential geothermal drillers complete an entire project in each 7-4pm workday. The estimated cost of installing loops for a typical home is somewhere in the $3,000 range. When we first learned about this, we didn’t believe it: it sounded way too good to be true. So we went to Sweden. And we were astonished to find it is real. How do the Swedes drill geothermal so efficiently? And how can we bring their equipment and methods to the US to expand our geothermal drilling capacity in this country? These are the questions and goals we’ve been focused on since our fateful visit to Sweden in the summer of 2021. In the time since, we’ve purchased the equipment the Swedes used, hired Swedish drillers to coach us, and starting implementing the Swedish model in NY and CT. While we aren’t yet nearly as good as the Swedes, the results so far have been very encouraging. In this presentation, our goal will be to illustrate what the Swedes do, and then describe ourselves as a case study, and report back on the impact that implementing the Swedish method has had on our throughput and costs. The Swedish method is not proprietary – anyone can do it. We are hopeful if we can spread the word about this, more people will start using this approach, and there will be more drilling capacity for geothermal in the US.

2:30pm     HDPE Pipe Integrity at Depth, Vertical Closed Loop Ground Heat Exchangers

Speaker:         Terry Proffer, Major Geothermal

Abstract:        The need for deeper vertical bores often leads to questions of loop integrity for both burst and collapse concerns. Yet experience has determined deeper boreholes (400’ to 700’+) are in fact compatible with current grades of HDPE pipe. Misinterpretation of the ASTM (D 2837) pressure ratings is the key reason for HDPE integrity concerns for deeper bore installations. This presentation will cite anecdotal deep loop installations (400’ +); review how pressure ratings are determined for different grades and schedules of HDPE pipe; how these ratings do not consider the downhole environment and conditions for closed loop vertical bores; describe pressure conditions both external and internal to deeper HDPE pipe installations; and conclude why HDPE pipe in deeper bores is acceptable.

10:15am    Utility Loop Ownership: Capturing the Earth’s Solar Energy for Utility Margins

Speaker:          Boyd Lee, CKenergy

Abstract:          CKenergy’s utility loop ownership experience takes the guesswork out of the positive financial benefits of being willing to “work outside of the box” to provide co-op members with savings, and the utility with increased profit margins. CKenergy has nine years of success with this innovative program that reduces peak demand, while increasing off-peak kWh and saving homeowners 40-70% over conventional electric systems and 30-50% over natural gas systems. The co-op provides cash incentives, installs the loop, retains asset ownership, and applies a monthly user fee as part of the monthly meter charge, creating a win-win solution for all involved. Boyd Lee will provide an overview of CKenergy’s success with utility loop ownership that can be replicated throughout North America to change the way we look at heating and cooling homes and commercial buildings in the future.

11:15am    Geo for Builders!

Speaker:          Steven Koep, PrairieFish LLC and Ryan Dougherty, GEO

Abstract:         Geothermal Exchange Organization conducted a targeted market engagement project that developed strategies to identify and engage with builders and developers (Custom, Green, Net Zero, etc.) who are open to utilizing GSHP technology in future projects. The effort involved communication and interaction with state-level builder groups and associations (HBAs), as well as other potential partners including electric utilities, state-level GSHP associations and other market participants and stakeholders. A preliminary assessment of the custom homebuilding (CH) market in 10 key states laid the groundwork for the introduction of the “GEO for Builders!” educational and awareness-building initiative focused on identified CH firms, with the ultimate goal of OEM engagement with these companies and increased utilization of GSHP technologies and systems.

8:00am      Optimization of Vertical Ground Heat Exchanger Design

Speaker:          Norbert Pepka, Affiliated Engineers

Abstract:          A key element of a successful ground source heat pump (GSHP) installation is a well-designed ground heat exchanger (GHX). Many times, rules of thumb or common mechanical design standards are applied uniformly across various design scenarios for both residential and commercial system. This may result in inefficient design and overall poor GHX performance. There are many parameters that affect a successful design. In a design phase of a vertical ground heat exchanger much importance is given to the vertical borehole itself and most of the time the lateral piping design is overlooked. This approach may compromise the energy efficiency and performance of the whole GSHP system especially with long lateral piping runs. Therefore, various aspects of a GHX design are discussed including bore hole spacing, bore diameter, bore depth, pipe size and material, number of circuits (U-bends), short circuiting due to various pipe lengths, together with best practices related to lateral piping being an integral part of a successful GSHP design and installation.

9:00am      Best Practices for Configuring Ground Source Heat Pumps for Net Zero Energy Buildings

Speaker:          Albert Wallace, Energy Environmental Corp

Abstract:         Truly sustainable commercial buildings reduce the energy use and carbon footprint for heating and cooling which represents 40% of the total energy use in the United States. In the past 10 years, substantial progress has been made to configure GSHPs appropriately with high mass hydronic cooling and heating systems to achieve net zero performance in dozens of commercial buildings. While traditional energy efficiency metrics focus on the coefficient of performance (COP) of a particular appliance, these net zero energy buildings have proven that the configuration and control of the installed systems has a far greater impact on overall building performance than heat pump COP. Specifying high mass building structures, separating heating and cooling from ventilation, configuring water-to-water heat pumps to double their COP, and using advanced controls based on historical and real time climate data are critical elements to achieve net zero performance. This presentation discloses the best practices to achieve these performance goals using a proven architecture implemented in the past several years in a number of large commercial installations. The presenter is an expert in these technologies with certifications as a CGD, CEM, LEED AP, and is an ASHRAE member with professional degrees in Aeronautical Engineering, Architecture, and Landscape Architecture. He has been awarded five U.S. patents for these net zero energy technologies.

Speaker:          Tyler Harbeck, GeoPro Inc.

Abstract:         The presentation will briefly define why to grout, how to grout, and the criteria of a high quality grouting product. It will provide insight into the different types of geothermal grouting products available and the important characteristics of each that impact system design/performance. Design scenarios will be used to provide an in-depth look at how density, material cost, and thermal conductivity all impact the “arbitrary” selection of grout in geothermal system design. The presentation will close with a summary using finite element analysis to compare the impact that thermal enhanced grout has on bore resistance in single, double, and quadruple u-bend configurations.

9:00am      Angled Drilling

Speaker:          Stan Reitsma, Geosource

Abstract:         Angled drilling for installation of geothermal systems can enable the installation of significant geothermal capacity in a small surface area, an area as much as an order of magnitude smaller than would be required for vertical heat exchangers only.  This makes the use of angled drilling particularly applicable to retrofit of buildings in areas of higher infrastructure density, with placement of geothermal infrastructure to avoid building structures, green space/landscaping, and other near surface or surface infrastructure.  In some cases angled holes are used to reduce overall construction cost or improve construction schedule. Examples of completed and future geothermal systems using angled holes are presented to show the flexibility that angled geothermal heat exchanger solutions provides.  Some design considerations are provided such as how to spread out boreholes effectively and when to consider using angled holes.  The presentation will also discuss how to accurately position rigs and why that is important.  A discussion on analysis of angled geothermal heat exchangers and how these fields behave will also be provided which ties into the discussion related to ongoing research and development.

Speaker:          Steve McGowan & Jeff Corey, Ground Loop Solutions

Abstract:        There are several things to take into consideration when installing a ground loop heat exchange whether it is a residential or commercial application, as the two are very different from each other. Based upon the presenter’s experience and “lessons learned”, this presentation will focus on the importance of planning for the many aspects involved in drilling, trenching, flushing/purging, hydrostatic pressure testing, creating an accurate site survey, and coordinating the various aspects of the installation from start to finish.

11:15am    The Importance of Field Testing

Speaker:          Dan Sergison, Endurant Energy

Abstract:          In the constantly-growing heat pump industry, a lot of focus has been placed on heat pumps themselves, rightfully so. However, an equally-important aspect of ground source heat pump system design has been increasingly overlooked: site-specific field-testing. While heat pumps can operate in an array of impressive conditions, the thermal and geologic conditions at a site provide the source and sink for those heat pumps. Understanding the dynamics between the heat pump and the ground is imperative to providing sound designs, from time and cost estimation for construction, through the entire life of the system. While researching the thermal and geologic conditions is important, acquiring actual field data adds immeasurable value to the overall ground source heat pump project. This presentation will explain the importance of gathering field data, what it can help to avoid and how it can impact geothermal heat pump projects.
