Best Practices for Designing Geothermal Systems

Geothermal Heating and Cooling is a complete revision of Ground-Source Heat Pumps: Design of Geothermal Systems for Commercial and Institutional Buildings, which is recognized as the primary reference for nonresidential ground-source heat pump (GSHP) installations. This new work takes advantage of the many lessons learned since the time of the original publication, when GSHPs were primarily residential applications.


Many improvements have evolved, and performance data, both positive and negative, is now available to guide the development of best practices. This essential guide for HVAC design engineers, design-build contractors, GSHP subcontractors, and energy/construction managers also provides building owners and architects with insights into characteristics of quality engineering firms and the information that should be provided by design firms competing for GSHP projects.

This revision draws on new ASHRAE and industry research in critical areas, as well as measured data from long-term installations and optimized installation practices used by high-production GSHP contractors. Nearly all chapters and appendices were completely rewritten, and they include coverage of closed-loop ground (ground-coupled), groundwater, and surface-water systems plus GSHP equipment and piping.

Additional information on site characterization has been added, including a new hydrogeological chapter. Another new chapter contains results of recent field studies, energy and demand characteristics, and updated information to optimize GSHP system cost. While other publications deal primarily with ground-coupled heat pumps, this text includes detailed coverage of groundwater, surface-water, and GSHP costs.

Tables, graphs, and equations are provided in both Inch-Pound (I-P) and International System (SI) units. As a bonus, supplemental Microsoft® Excel® macro-enabled spreadsheets for a variety of GSHP calculations accompany the text.

Geology and Drilling Methods for Ground-Source Heat Pump Installations: An Introduction for Engineers


This manual is intended to help the designer understand the driller's tools, techniques and the ground they   penetrate. It includes an introduction to geology, hydrogeology, soil development, and other conditions that impact the feasibility and economics of ground-source heat pump system installation.
