Draft Scope/Description:

1.1  Scope

This Standard applies to standing column well (SCW) earth source heat exchangers which are to be connected to a ground source heat pump system and used as a thermal source or sink for heating and cooling applications.

Note: In certain jurisdictions, a “dual purpose SCW” can also serve as a residential water well.  In those jurisdictions, additional requirements can apply.

1.2  Inclusions

This Standard also applies to the standing column well heat exchanger, in-building interface, and geothermal heat pumps portions of a thermal energy transfer system.

1.3  Requirements

This Standard covers the minimum requirements for site survey, material selections, electrical, flows, testing and verification, documentation, commissioning, maintenance, and decommissioning of residential and commercial and industrial (C&I) standing column well applications.  In-building integration is also covered in this Standard.

1.4  Units

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.

1.5  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 (nonmandatory) to define their application.
