1.1 This practice details the minimum requirements for installation, testing, commissioning, and maintenance of closed-loop, ground source geothermal heat exchangers. These requirements provide the installation steps to construct closed-loop, ground source geothermal heat exchangers. Specifically dealing with institutional and commercial installations, this practice covers a broad spectrum of applications and shall be focused on proper processes to ensure quality. 1.2 This practice does not cover the internal building loop or equipment requirements of this type of installation. 1.3 This practice shall not dictate specific design criteria or favor any product or technology. 1.4 This practice shall be focused on the proper, documented process required to build a quality, cost-effective closed-loop geothermal heat exchanger. 1.5 Integration of best practices shall be relevant to this practice and promote a mechanism for rapid evolution and reaction to changes or events. 1.6 This practice shall be divided into four key areas: 1.6.1 Installation, 1.6.2 Testing, 1.6.3 Commissioning, and 1.6.4 Maintenance. 1.7 Safety and hazard considerations unique to this application, such as drilling, trench safety, and proper equipment operation are addressed by other codes, standards, or authorities having jurisdiction. 1.8 This practice provides guidelines for minimum processes required and shall be used in conjunction with applicable codes and standards, requirements, manufacturer requirements, and best practices. 1.9 This practice is not intended to replace or supersede any other applicable local codes, standards, or licensed design professional instructions for a given installation.
