The next generation of buildings will have to do better than just energy efficiency and recycled materials. Our lack of foresight has made our buildings toxic, wasteful and unaffordable. Simply “being less bad” isn’t enough and will delay our progress for generations. In order to undo the damage of the past, we need innovative, new models for how to build deep green, bio-based buildings.

This Marketing Track Course will cover the selling points of geothermal HVAC systems using a more practical and tangible alignment of priorities by focusing on the needs of building owners based on trends in the market. Particularly, many consumer/owners have grown weary of hearing [inflated] claims of energy efficiency from all sectors. This gives a fresh perspective in light of recent storm related equipment damage (New York Times), and general longevity of geothermal equipment, aesthetics, and peripherals common to geothermal HVAC technologies. Generally, the course will outline the marketing of geothermal systems on the following points in this order: 1. Elimination of outdoor equipment, 2. Storm proofing (NYT), 3. Longevity of system, 4. Elimination of fresh water consumption (cooling towers), 5. Elimination of fossil fuel consumption (on-site), 6. Superior comfort in heating and cooling modes, 7. Enabling thermal load sharing, 8. Efficiency of system

Jay Hammond
GeoMaster LLC
This presentation will cover what I believe is the hardest part of being in the geothermal industry - teaching the average contractor to not only sell a geothermal system, but to insure that the system “sells” itself to other potential customers. With the advent of more “educated” customers and the information available on the Internet and other media, contractors need to be taught to properly use all of the tools available to make the sale. Tax credits simply aren’t the only sales tool that we can use.
In our current economic condition, tax credits are certainly a plus - but to some contractors they aren’t enough or have caused more competition, bad installations, or inflated the installation costs. I will discuss how to combat poor installations, how to properly present a geothermal system to the homeowner, and what to do after the installation to garner additional sales.

Why is it different from solar, wind, hydro, bio-fuels, and other renewables? Why is it not the FIRST thing that comes into the public’s mind when they think of being sustainable and renewable?What are the federal tax laws doing for, or, against GSHPs when compared to the other renewables. What is going to happen after 2016 and the “tax credits” are gone? What is happening now?
This will be a critical conversation concerning our industry and where we want to be in the future.

One of the current trends in GSHP equipment EERs is definitely upwards. Do installed operating systems realize these values? How do you compare these values to energy efficient air-source heat pumps? What do these numbers tell us and what do they mean to the building owner? In this presentation a brief discussion about different equipment rating systems will be introduced followed by an example for determining mechanical system efficiencies. This approach may be used for comparing geothermal heat pump systems to emerging and conventional mechanical systems.

A client in Kansas City converted their facility from rooftop units to ground source with the understanding that the facility would be more energy efficient. After two years of operation the ground source system was operating less efficiently than their old rooftops; WHY? After retro-commissioning the converted system, the system was retrofitted with a simplified pumping design in hopes that the operational difference would be eliminated. After the retrofit, the heating and cooling costs were reduced much more than anticipated, an average monthly HVAC energy savings of nearly 70%. How did this happen and why?

Hybrid geothermal systems are both an opportunity and a risk. They are an opportunity because they can reduce upfront geothermal installation costs, balance loads and encourage more people to try geo. They are a risk because proper hybrid loopfield and mechanical equipment sizing can be a challenge. In this seminar, take a sneak peak at the new advanced hybrid design and simulation tools in GLD2014 that will help you size hybrid systems quickly and accurately.

Ground source heat pumps have been designed and installed in a commercial turkey farm in Cooper County, Missouri, as an alternative to heating by propane. Propane is the only option for most poultry farmers in rural areas of the U.S. Challenging requirements of poultry farm heating include high baseline prices of propane, indoor temperature requirements as high as 92° Fahrenheit, and long heating hours annually, make heating fuel the largest operation cost for most poultry farmers. Benefits of GHP are not only significant energy savings, but also air quality improvement. Propane heating is always associated with substantial water generation inside poultry houses. High moisture levels result in high ammonia concentration through the interaction of water and bird manure. In order to keep ammonia under an acceptable level, large mechanical ventilation systems are required. GHP provides a clean and “dry heat” and helps to minimize ammonia and bacterial generation. Detailed project information including design and installation will be given in the presentation.

It’s possible to design a vertical or a horizontal GHX for a building, and both will operate efficiently to provide the heating and cooling the facility needs. A horizontal GHX, however, actually works quite a bit differently than a vertical GHX because of the impact of the atmosphere on the piping that is buried only a few feet from the surface. Heat rejected into the horizontal piping dissipates very quickly to the atmosphere during colder weather. In summer, solar energy warms the earth around the shallow piping of a horizontal GHX, while the impact on the earth around a vertical borehole at a depth of 100’ cannot be measured. Conversely, a deep vertical borehole cannot take advantage of solar energy striking the ground, nor can it dissipate heat to the atmosphere quickly. By integrating a vertical and horizontal GHX into one system, it is possible to take advantage of the different way the GHX’s work. There can be some significant benefits to combining different types of heat exchangers into a GCHP system. A project in Kalgoorlie, Australia, is used to illustrate the design and advantages of this approach.

Only a few years ago a geothermal heat pump was a simple electromechanical device where all a technician needed was a flashlight, screwdriver and a good sense of smell. Today heat pumps have been enabled for communication to simple service tools and information displays. What are the lessons learned from other industries as they have gone through this first transition and far beyond into the connected world, where the networked device is literally the engine that drives the business.

For low operating cost, precise temperature control and low sound levels, consider inverter technology for your next geothermal job. These 3 and 4 ton units use Daikin variable speed technology in a water source heat pump. Our 4 ton unit modulates down to 1˝ tons and up to 5 tons for a wide operating range. As the compressor slows down, the EER increases. EER’s on the 3 ton unit go from 20.4 EER at full load (35,600 Btu/hr.) to 47.3 EER at part load (15,600 Btu/hr.) – all at ASHR Ground Loop conditions. Additional features include ECM fan motor, optional electric heat, desuperheater and desuperheater pump. The end result is no more over or under-cooling/heating, minimal temperature fluctuation in the space since the compressor is not cycling on and off, better humidity conditions due to longer run time and lower sound levels.

GX District Energy and Environments in the West
A look at the progress of two District Energy systems and a unique program to re-populate an endangered species, the Devil’s Hole Pupfish. Cashman Equipment Caterpillar Dealership in Las Vegas, NV is a 310,000 sq. ft., seven building LEED Silver facility that has been operating for just over five years. Cashman has been very proactive in managing and tuning the HVAC system to optimize energy use and reduce consumption. It was part of a DOE study on Hybrid Systems in 2011 by the Energy Center of Wisconsin. The second project is the story of designing and installing a hydronic GX system to control the temperature of a 100,000 gallon tank that mimics the natural environment of the Devils Hole Pupfish by +/- 1.5 degrees C. The efforts to save this species of pupfish and a U.S. Supreme Court decision helped to precipitate the Endangered Species Act of 1966. The third section is an update of the district energy system at Colorado Mesa University in Grand Junction Colorado. The first portion of this GX district system (~2,200 tons) was commissioned in the fall of 2011 and has been very successful in reducing energy cost and consumption. This summer the system was expanded (~2,200 tons) to cover the new classroom buildings and dormitories under construction, and is scheduled to add the university field house and natatorium in 2014.

Everybody knows the three key barriers to geothermal adoption, lack of awareness, lack of trust, and upfront cost. However these are not barriers of the technology but consequences of the business model chosen to sell and deploy it. Leaving behind the “savings based” sales model that depends on incentives and consumer tax credits for a sales model based on profit and resilience, while still lowering price volatility and consumer costs. This presentation shows how a different, utility driven sales and ownership model is evolving to dramatically move geothermal sales from 2% to the mass market.

California is a paradox whose history for energy conservation and technological achievement led to a regulatory approach favoring solar and renewable electricity over GHPs. Recognition of GHPs’ permanent electric load reduction and GHG reduction could lead to full or partial credit in electric utilities’ Renewable Portfolio and perhaps on-bill financing.

Description: The Orca Geothermal Utility model has been successfully implemented in Canada for 10 years, and is now being rolled out across the United States. By removing the initial cost barrier from the equation, the implementation of geothermal systems will increase dramatically. This tool allows home owners, developers and contractors alike to install geothermal systems where they may otherwise have not. With the help of the various tax credits and rebates, the installation of a geothermal system will now be less expensive than conventional systems. Furthermore, stable long term utility rates result in cost certainty and peace of mind to the end user. This presentation will explain how the Orca utility model will change the way geothermal systems are delivered.
