Geothermal Heating & Cooling Survey

The 2009-2010 Geothermal Heating and Cooling Systems State Regulatory Oversight Survey represents the most complete and accurate information for geothermal system regulation available anywhere. The report is designed to allow readers to easily compare state regulations as well as aggregate data on all responding states.

The report is divided into two major sections. The first section contains a quick graphical overview of which geothermal systems are regulated. The second portion shows aggregated data for all responding states and each state's individual answers.

Guidelines for Construction of Loop Wells for Vertical Closed Loop Ground Source Heat Pump Systems


Edited by Jonathan T. Jenkins
NGWA Press
Digital Document

This third edition was put together by an NGWA volunteer work group to provide updated information on the original Guidelines that was published by NGWA in 1997 and then updated again in 2009.

The guidelines are written for loop well contractors, loop well design consultants, government officials, educators, students, and consumers.

It is a stand-alone document that does not supersede regulations or standards, and provides details on issues related to the construction of vertical closed loop ground source heat pump systems and offers insights to practical resolutions of the issues.

Intro to Numerical Modeling GW

By J. Bundschuh and M.C. Suarez Arriaga
CRC Press

This book is volume two in the multi-physics modeling book series. It provides an introduction to the scientific fundamentals of groundwater and geothermal systems.
In a simple and didactic manner the different water and energy problems existing in deformable porous rocks are explained as well as the corresponding theories and the mathematical and numerical tools that lead to modeling and solving them.
This approach provides a thorough understanding of the basic physical laws of fluid flow, in thermoporoelastic rocks, the partial differential equations representing these laws, and the principal numerical method that allow finding approximate solutions of the corresponding mathematical models. The book also details the form in which specific models can be generated and solved.

Introduction to Thermogeology

By David Banks
Wiley-Blackwell

This book provides a basis for understanding the emerging technology of ground source heating and cooling.
It equips engineers, geologists, architects, planners, and regulators with the fundamental skills needed to implement technologies for space heating and cooling.
The book is geared toward understanding ground source heating and cooling from the ground side (the geological aspects) rather than solely the building aspects.
This second edition is thoroughly updated and expanded to cover new technical developments and now includes end-of-chapter study questions to test the reader's understanding.
