Project NEGATHERM for Ground Source Heat Pumps:

(Improving the Geothermal Borehole Drilling Environment in California)

This July, 2011 Document was written by Dennis Murphy (Green Building Council of California and founding member of CaliforniaGeo) for the California Energy Commission as document CEC-500-2011-025.

The Project Negatherm Report defines and breaks down the stumbling blocks to drilling ground-source heat pump boreholes by investigating specific regulatory, technological, and financial hurdles across California. Featuring surveys and interviews of consumers and key representatives of the drilling and ground source heat pump communities, this report pinpoints areas for improving interactions between government, utilities, business, educators, and the public and delivers detailed recommendations for regulatory reform, best practices and information sharing.
