About Jeff Harrison

Jeffrey J. Harrison, PE-Retired-inactive (Maine) Currently retired and looking for part time work in design or engineering or contract short term projects. Jeff Harrison has been a consulting engineer providing mechanical, plumbing and fire protection services in the State of Maine and throughout New England since 1979. Most recently as an applications Engineer for Blake Equipment (BE), specializing in Alternative Energy, Mr. Harrison provided “Peak Energy Performance Solutions” facility energy review services as part of a comprehensive plan to convert buildings from fossil fuels to integrated hybrid thermal solar and geo-exchange energy systems. Beginning about 2012, Mr. Harrison began working with Geo-exchange systems from a forensic engineering perspective to understand why systems were routinely under performing from expectations. Based on this in depth understanding of the science of how geo-exchange works, Mr. Harrison developed a new paradigm for “Near Net Zero Energy HVAC by Design” that encompasses more efficient borehole heat exchangers, more efficient pump and piping optimization, utilization of high efficiency frictionless chillers for geo-exchange, and other aspects for a system wide approach ultimately resulting in a fourfold increase in geo-exchange BTU/$. At Blake’s new warehouse facility in CT, he has installed a geo-exchange research facility with 4 different borehole heat exchanger styles to monitor and measure performance for comparison to commercial software calculation models for improvement of the software used in the industry. While with Turner Building Science, Mr. Harrison developed and received a patent for hybrid integration of thermal solar and Geo-exchange into a combined system for higher efficiency. Designing and installing both horizontal and deep borehole closed loop geo-exchange systems have included many variations for hybrid thermal solar / geo-exchange heating and cooling systems This hybrid application of his collection of peak performance equipment typically provides more BTU’s / dollar than previously engineered systems. Previous to joining BE, Mr. Harrison spent 6 years as a principal with Turner Building Science & Design, 16 years as the principal of Building Tech Services - Consulting Engineers, 10 years as a mechanical engineer with Neill & Gunter, Inc, providing industrial HVAC, Process and Power Piping and general mechanical consulting engineering services and two years working for Carrier Corp. in the industrial chiller department.
