Cider and Fishnets

Ed Lohrenz, GEOptimize Inc.

What does cider have to do with fishnets? For starters, producing cider and cleaning fishnets used in fish farming operations both use a lot of energy, and companies that produce cider and service fish nets are as interested in reducing energy costs as the rest of us. Saving energy gives them a competitive advantage and is good for the environment. Ground source heat pump technology can be applied to a wide range of agricultural and industrial processes. This presentation describes how ground source heat pumps were used in to produce cider and service fishnets more efficiently.

Water Utilities Offer an Alternative Method of Delivering Geothermal Technology

Kendra Morris, American Water Jack DiEnna, GEO-NII Don Penn, IEG

Water utilities are poised to become major players in geothermal technology by using municipal water supply as the medium for heat exchange. American Water, the country’s largest publicly traded water and wastewater utility, is using an innovative approach to traditional geothermal technology. By eliminating the need to drill boreholes, American Water’s geothermal systems significantly reduce initial construction costs. Partnering with Jack DiEnna of GEO-NII and Don Penn Consulting Engineer, American Water has two pilots in operation using potable and reuse water to provide heating and cooling to buildings. This session will discuss the various benefits and results of these projects and the long term advantage that this method brings to the industry. This project was done in partnership with Bosch Thermotechnologies.

Converting Architects to Geothermal

Jay Egg, EggGeothermal

Architects may be one of the stumbling blocks that can stop an otherwise perfect geothermal project from going forward. To some of these professionals, geothermal heating and cooling is an unknown. While it may seem important to work through the owner or even the engineer, the architect can be a difficult hurdle. Architects are also reasonably easy to convert, but how do we get the full attention, then what level of information do we share?

This presentation will provide insightful real-life ways to penetrate the architectural barriers that affect some projects. Additionally, it will provide information on what to share, and what not to share when you get in front of an architect. This presentation will go through some of the recent success in New York, and with IGSHPA in our efforts to focus on the architectural community.

Conducting lunch-time (sometimes referred to as “Lunch-and-Learns” geothermal information, question and answer session at an architect’s office can provide impressive results. The presentation will share successful projects featured by Commercial Architecture Magazine such as Rancho Los Alamitos in California. We will also focus on the new curriculum available for architects that was developed in New York, and is now (will soon be) available online from IGSHPA.

Roles of Third-Party Sanctioning Toward Ground-source Heat Pump Installations Achieving Energy Savings Performance

Kevin McCray, Kevin McCray Consulting, LLC

Some in the ground source heat pump technology advocacy community contend some installations fail to achieve their anticipated energy savings performance. The existence in the marketplace of a consensus, third-party-sanctioned standard of practices, and one that may also be cited in regulation and rule, may not also be assurance a GSHP system will meet or exceed a designed for or promised for energy savings performance.

Attributed, but unmeasured, causes for this contention include:

  • Certification and/or licensure of the various professions involved from start to finish in a ground source heat pump installation;
  • Government oversight associated with ground source heat pump installation;
  • Appropriately-timed inspection of the major system components of a GSHP installation.

This presentation will review the limited feedback received from industry professionals in a survey about assumptions perhaps leading to underperforming installations.

An Analysis on Cost Reduction Potential of Vertical Bore Ground Heat Exchangers

Xiaobing Liu, Oak Ridge National Laboratory Defeng Qian, University of Alabama Joshua Mcdonald, University of Tennessee Yarom Polsky, Oak Ridge National Laboratory

The cost for installing ground heat exchangers (GHXs) used for ground source heat pump (GSHP) systems usually accounts for more than 30% of the total cost of a GSHP system and it is the biggest contributor to the cost premium of GSHPs compared with conventional HVAC systems. This study evaluates the cost reduction potential of several possible improvements in borehole heat transfer, borehole drilling, and bore field layout. A detailed cost model for GHX installation was updated and new features were added to account for various GHX designs, geological conditions, and drilling technologies. Coupled with a well-established GHX sizing program, a systematic study was conducted to assess the impacts of these improvements on the needed total drilling length and resulting cost under various geological and loading conditions. Finally, improvements with significant potential to reduce GHX installation cost are recommended

Remedial Design Success for a K-12 School, San Luis, CO

Terry Proffer, Major Geothermal Beth Doty, BDK Engineering PLLC Corey Chinn, Farnsworth Group

The original system for a 75,000 ft² K-12 school, in San Luis, Colorado included one water-water heat pump and a horizontal ground heat exchanger (GHX). Comfort issues and high operating costs began in the first winter of operation; remedial efforts failed. 3rd party forensics commenced in 2012. Forensic reverse engineering determined the central plant undersized and incompatible with closed loop operating conditions; classroom radiant baseboard insufficient and incompatible with loads; problematic outside air management; multiple control conflicts; etc. Remedial design was completed in 2016, utilizing water-air heat pumps and water-water heat pumps for limited radiant floor heat and tempering of outside air. A vertical GHX was installed to supplement the existing GHX, controlled to optimize the performance of the combined fields and operational COP. This presentation describes the evaluation process, determination of effective solutions, the value of peer review and commissioning throughout the project to provide and prove system integrity.

Strategies and Controls for Radiant Floor Cooling with Ground Source Heat Pumps

Albert Wallace, Energy Environmental Corporation Maya Kadi, Energy Environmental Corporation

Hydronic cooling systems significantly outperform forced air cooling while providing superior comfort and indoor air quality. Yet implementation has been limited by commercially-available controls. Unlike boilers and chillers, the market potential is vast for GSHPs which provide hot or chilled water at higher efficiencies. Through direct use of ground heat exchanger fluids and reversing fluid flow in snowmelt systems, EERs can exceed 170 and system COPs can double. For these reasons, one third of zero net energy buildings will implement these technologies. Unfortunately, adoption presents substantial technical and business risk for radiant cooling dew point and GSHP integration controls. The presenters address these issues using actual case studies in parallel with a proven systems model. Design professionals and contractors will benefit from this presentation by gaining the competitive advantages which create new business opportunities, and understanding how controls and licensing for turnkey solutions can be achieved quickly and cost effectively.

How to Achieve State and Local Tax Credits and Grants

Steve Weitzel, WaterFurnace International Bret Ross, WaterFurnace International

Over the last several years Federal and State incentives have aided in doubling the annual number of geothermal installations in the United States,

  • Creating tens of thousands of new jobs.
  • Driving down the cost to consumers by 20%.
  • Adding energy security for our country.

2016’s successful effort to win a 25% tax credit from the State of South Carolina combined professional lobbying with a grass roots effort to get House and Senate members out to job sites to witness the benefits first hand. The outline for success is in place. State by state replication is the answer.

Ground Source Heat Pump System Forensics

Terry Proffer, Major Geothermal

Forensics for problematic GSHP installations is no different than for other types of mechanical systems in that the fundamentals and perspective of the entire basis of design need to be understood before diagnostic efforts can begin. However, specific differences unique to GSHP systems must also be accounted for including the ground heat exchanger, controls sequence of operation compatibility for extended range heat pumps, and impacts typically not as significant to other system types but more sensitive for GSHP applications. Using basic evaluation procedures, root causes of problems may be identified, sometimes resulting in simple and cost effective corrections. This presentation will describe several problematic examples encountered for commercial and institutional installations, ranging from underperforming to catastrophic system failures, identification of issues, and best solutions determined to rectify same.

How an Optimized Hybrid Geothermal System Yields a Small Commercial Building Total Operating Cost of Only $0.45 per Square Foot per Year

Todd Giddings, Todd Giddings and Associates, Inc.

This case-history example will explain how an open-loop geothermal heat pump system was optimized to yield a HVAC, lighting, hot-water, and plug-in load total cost of $0.57 per square-foot per year in a 10,000 square-foot office building in a 5,600 heating degree-days climate.  A 27 kW photovoltaic solar power system was then added to create a hybrid photovoltaic solar – geothermal system that is yielding a total building operating cost of only $0.35 per square-foot per year.  The summer-season demand reduction caused by this hybrid system design will be explained.  Monthly and annual monitoring data from the 12 electric meters in this building will be presented to show the seasonal variation in the photovoltaic solar output and the heating and cooling loads.  The energy-conserving aspects of the building envelope will be shown to explain their role in the extremely low total building operating cost of $0.35 per square-foot per year.

Sustainable Sales for Geo

Pete Prydybasz, B.J. Terroni Company, Inc.

Understanding the benefits of Geothermal provides many tools mitigating many socio-economic and environmental issues we face today: the reduction of greenhouse gasses, oil markets, the production of electric, affordable operating costs. These benefits are not being recognized by the end user.

Most innovations by the present “Geo Community” are pointed to the trade. The constant development of means to achieve higher COP’s and EER’s, pump technology and loop sizing software. While all of this is necessary it does not include the end user. The end user pulls the cart. This is evidenced by this year’s major drop in sales. The Geo Market cannot exist let alone to grow if the only motivating factor is a tax credit. Presenting an orderly approach to bidding, installation and Low-cost financing schemes currently available could be applied to present a very strong case for geothermal.

Design Factors Affecting the Collapse Pressure of HDPE Pipe in Vertical Closed Loop Ground Heat Exchangers

Mathieu Brousseau, VersaProfiles Inc. Jean-Francois Lavoie, VersaProfiles Inc. Jasmin Raymond, INRS Jeff Harrison, The Blake Group

This study is about the effect of the design parameters of ground heat exchangers (GHE) on the collapse pressure of the pipe at depth. The collapse pressure depends on the properties of both the grout and the pipe. The pressure balance at depths of the GHE was calculated to determine the pressure exerted across the pipe wall. Both the standard PE 4710 and the thermally enhanced (TE) high density polyethylene (HDPE) pipes were compared in different pipe sizes and dimensional ratios. Theoretical and experimental collapse pressures were examined. Pipe wall pressure at depth was compared with the collapse pressure. Results indicate that the collapse pressures are larger in TE pipes. Simulations and cost analysis suggest that GHEs installed with TE pipes can sustain of thinner wall thickness and/or deeper boreholes, compared to those equipped with standard HDPE pipes.

Influence of Water Injection on the Relevant Heat Transport Process in Groundwater Heat Pump Systems

Byeong-Hak Park, Seoul National University Kang-Kun Lee, Seoul National University

The thermal dispersion increases with flow velocity and has a wide range of values in the field. Since groundwater heat pump (GWHP) systems use a great deal of groundwater as an energy source, the natural flow field can be greatly disturbed by pumping and injection. Therefore, the increased velocities around pumping and injection wells can increase the influence of the thermal dispersion on the heat transport.

In this study, a laboratory experimental device was designed to investigate the effect of water injection on the advective-dispersive heat transport. The device mainly consists of the acrylic glass tank filled with the fully-saturated sand, and the sensors such as RTDs and EC probes were installed inside the sand tank. First of all, pre-tests such as grain size analysis and static permeability test were conducted, and then heat tracer tests using two different heat sources were performed with various background flow.

Delivering Integrated Sustainable Energy Solutions Using Energy Foundations

Tony Amis, GI Energy

Large-scale GSHP systems, specifically using energy foundations, can be extremely successfully integrated into other renewable solutions to provide enhanced energy savings. We will include practical design, build and long-term management considerations, and cost estimating criteria. Our presentation will be based around case studies, to illustrate the myriad ways to implement this technology. Cornell Tech on Roosevelt Island, NYC is a groundbreaking GSHP system, intercepting water-filled fissures in the local bedrock. The system then takes advantage of this water to increase its efficiency. It is the first time in the USA a supplemental groundwater pumping system has been applied to a closed-loop geothermal system in this way. Oxford University & University of Chicago demonstrate the practical application of energy foundations within a campus setting, whilst The San Francisco Shipyard is a 10,000 home ‘eco-grid’. Finally we can discuss how successful smaller projects can be, such as Trevor Day School in NYC.

Financial Incentives for the Installation of Ground Source Heat Pump Systems

Kevin McCray, Kevin McCray Consulting, LLC

More than 500 financial incentives in 14 different forms have been made available to help to advance the number of installations of ground-source heat pump systems in residential and commercial structures in the United States. Due to inadequate market data availability, it is difficult to conclude about the national impact of financial incentives. An examination of a sampling of several state markets and a regional market within a state with known numbers of GSHP installations and available incentives may suggest incentives have not stimulated GSHP market growth or have had negligible impact, but theoretically could be the cause of all installations in a geographic market.

Full Scale Experimental Procedure for Comparing Geothermal Probes Under Laboratory Conditions

Vincent Blouin, Clemson University

This project consists of studying and comparing the performance of two geothermal vertical probes, a 5.5-inch coaxial pipe and the commonly used 1-inch U-bend. The experimental setup is designed to be able to test the performance of each probe under any desired operating conditions. It consists of the two probes installed in the ground 30 feet apart and a two-ton geothermal heat pump. The thermal load applied on the system is generated by a water tank whose temperature is controlled by a secondary 3-ton air-source heat pump. The heat transfer characteristics of the probes are measured using integrated flowmeters and temperature sensors. By controlling the temperature of the water tank, any time-dependent temperature profile can be imposed as a load to the geothermal system at any time of the year independently of the season. This paper discusses in detail the experimental setup and preliminary results.

Heat Pump Opportunities Using Hybridization and Seasonal Thermal Storage

Gaylord Olson, Seasonal Storage Technologies Jim Thomas, Thomas Geothermal Engineering Yao Yu, North Dakota State University

Using an air source heat pump, the variations of outdoor temperature lead to limitations in both Coefficient of Performance (COP) and the capacity of the system. One way to overcome these shortcomings is to use an underground loop with a Water-Source Heat Pump (WSHP). However, the integration of a heat pump unit with a single energy source will not maximize energy savings and may not optimize system cost-effectiveness. This paper describes a multi-source or hybrid system for more efficient and cost-effective space conditioning. The system consists of a WSHP, a dry cooler (air to liquid heat exchanger), and a lower cost horizontal underground loop designed to enhance long term (seasonal) thermal energy storage. This system enables the alternate use of a dry cooler (air-source mode) and an underground loop (ground-source mode) with computer control of the choice depending on which source temperature is best at any given time.

Advanced Thermal Response Testing: Lower Cost and More Accurate

Rick Clemenzi, Geothermal Design Center Xiaobing Liu, Oak Ridge National Laboratory

Accurate GHEX design requires Ground Thermal Response Testing (TRT). TRT use is limited because of high cost and availability only from specialty contractors. The central problem is the current absolute requirement of nearly perfect electric power and thus the need for an expensive diesel generator.

We have developed a new way to perform TRT that eliminates any need for an expensive generator and shortens the test time to less than 24 hours. We further advance TRT results to now also report actual grout thermal conductivity (TC). Actual installed grout TC has always been an unknown, and studies of multiple wells within a limited area has shown that grout consistency is very erratic generally due to vendor error. Our new Advanced TRT methods, for the very first time, can confirm whether installed grout TC is or is not as contracted. This is a significant advancement for the GHP industry.
