Monitoring

GeoVision Collection and analysis of data from actual geothermal heat pump (GHP) systems is essential to improving confidence in the technology.  With improved confidence that the systems will provide the desired benefits -- reducing heating costs and carbon emissions -- homeowners and business owners will be more likely to adopt this technology as they update their heating systems.   Documenting performance at scale will enable financial institutions to provide services that will make the technology accessible to all income levels. 

While there have been several research projects to provide these analyses, they are very costly and limited in scope and duration.   These projects typically focus on a few systems and collect high-quality data for a year.   While these studies have provided insight into system operation and performance, they do not address the needs of system owners that want to insure that their system operates correctly.

To support the widespread availability of system monitoring, Davis co-founded a private equity-financed small business that developed and marketed a web-based monitoring system for individuals to track their own systems.   In 2012, the Department of Energy (DoE) published a roadmap for the research that would enable the widespread adoption of GHP technology, recognizing the need for data from actual system as the highest priority, and acknowledged Ground Energy Support as helping to meet that need.

ges-logo Over the past decade, Ground Energy Support has deployed over 150 GHP monitoring systems in 25 states and Canadian provinces, amassing over 250 million records of operating data. These data provide insights into the operation of actual systems using a variety of configurations for the ground heat exchanger and the equipment installed in the building.  GES has worked closely with UNH in licensing of anonymized data in support of the collaborative research under the US DoE SBIR/STTR program.
