Draft Scope/Description:

1.1       Inclusions

This Standard applies to ground heat exchanger systems that use groundwater to provide a heat source (and/or heat sink) for ground source heat pump systems.  These systems pump water from aquifers to be used as a heat exchange medium in a heat pump system and return the water to the same aquifers. These systems are commonly referred to as ”Open Loop Systems” or  “Aquifer Thermal Energy Storage Systems (ATES)”.   

1.2       Requirements

This Standard covers the minimum requirements for site survey, design considerations, material selections, installation, testing and verification, documentation, commissioning, and decommissioning.

1.3       Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.4  Units of measure

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

The values given in US customary units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
