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.

An earth energy system (EES) is a type of heat pump system that uses the ground or groundwater as a source of energy. This guide provides information needed to understand, plan, oversee, design, build, and manage an EES for heating & cooling applications in commercial & institutional buildings. Chapter 1 provides an introduction to EESs, what they are, where they make the most sense, how they work, and their economics as compared to other heating, ventilating, & air conditioning systems. Chapter 2 describes the different configurations or types of EESs and factors to be considered when selecting an EES. It also introduces the energy efficiency descriptors for heat pumps used in EESs and discusses the importance of energy efficiency in other aspects of buildings. Chapter 3 provides a brief overview of an EES design. Chapter 4 examines other important matters unique to EESs, such as environmental & legal considerations and planning, installation, & maintenance issues. Chapter 5 contains a detailed examination of topics pertaining to heat pump performance & efficiency. Chapter 6 discusses the evaluation & calculation of building loads & energy use. Chapter 7 explains the requirements for sizing heat pumps and ground heat exchangers, and includes sample calculations. Chapter 8 outlines factors to consider in the analysis of an EES investment and includes an economic & financial calculation example. The final chapter addresses practical issues that should be considered in EES design & installation. It also provides a sample performance specification and a list of important information to obtain from suppliers & contractors. Appendices include EES case studies and a glossary.
