Ground-source heat pump technology has not yet enjoyed the wide-spread deployment in California that has been experienced in many other regions in the United States. This is due to many reasons, somewhat unique to California. Regardless, the focus of this presentation is to share the challenges and triumphs of a local California Community College District, an early adopter of the GSHP technology, regarding their original GSHP system installed in 2006 and the current development of Central Utilities Plant scheduled to begin construction in 2015.

How to Use Stiff-Foam to Air-Rotary Drill Through Caving Overburden
The stiff-foam drilling method uses significantly less air volume and creates a pseudo-wall-cake to minimize the collapsing of the caving overburden and to decrease the erosion of the borehole wall. This innovative air-rotary drilling method can eliminate the need for temporary casing while you loop and grout the borehole, and can be an alternative to mud-rotary drilling.

Ed Lohrenz
GEOoptimize, Inc.
A big part of the cost premium for a ground coupled heat pump (GCHP) system is the cost of building the ground heat exchanger (GHX). Considering the options available for designing the mechanical system, the opportunities available on the site and the capabilities of GHX contractors in an area makes a significant difference in the cost of installing a GCHP system, the cost of energy to run it as well as the long term cost of maintaining the system. All of these factor into the owners decision to choose to install a GCHP system versus a conventional system. The cost of the GHX for a large commercial project was reduced by 80 percent and energy cost savings were doubled by considering changes to the design of the mechanical system and the configuration and construction of the GHX.

Steve Hamstra
Greensleeves LLC
The use of advanced computational tools and algorithms brings new applications and economies when designing, commissioning and optimizing the on-going operation of heat pump based HVAC systems. These tools can often reduce the first cost of a geothermal heat exchanger by more than 50 percent while meeting or exceeding the operational efficiencies of a full-sized (non-hybrid) application. Additionally, performance feedback and future operational prediction capabilities bring self-adapting and self-healing attributes to these systems. This seminar will summarize the design process, the tools and provide actual case studies of how this approach is being highly effective in our market.

Construction of a “Slinky”® Style Ground-Coupled Heat Exchanger
Ground-coupled heat exchangers for geothermal heating/cooling systems unite thermal needs of a building and thermal capacity of available ground, using excavation or drilling equipment to place High Density Polyethylene Pipe (HDPE) into soil in the most efficient manner. Each underground system is customized to site and circumstances. Design parameters vary among configuration options but comparable thermal exchange can be achieved. For structures up to 50,000 square feet or 150 tons of cooling capacity, a horizontal, “Slinky”®-style ground-coupled heat exchanger may be most expedient or cost effective to install. Slinkies concentrate partially-uncoiled pipe in trenches or pits that are shorter or more compact than those used for straight loops. Documentation of heat exchanger location, configuration and components benefit future building operators and occupants not familiar with a site’s history or underground features. Subsurface conditions can only be visually documented while exposed during construction. Photo series, slide shows or PowerPoint® presentations can provide such a record.
