The book was written by Steve Kavanaugh, professor emeritus at the University of Alabama, and Kevin Rafferty, a consulting engineer from Klamath Falls, Ore.

“One of the realities of the GSHP industry is that, to some degree, it has been a victim of its own success,” Rafferty said. “Years ago the struggle was to simply get design teams to consider using the technology. Though this is still an issue in some areas, nationally it is far less an issue than 20 years ago.  There is now fairly wide recognition of the benefits of GSHP systems, particularly on the part of building owners in the schools and office-building sectors where the technology has achieved its highest penetration rates.”

The book provides engineers design strategies, benchmarks and information needed to create the most efficient and cost-effective systems. It also will help engineers avoid problems such as inefficient pumping, high-cost ground-loop designs, inadequate outside air provisions and other problems.
