    Title, Purpose, and Scope

    1 Purpose: The purpose of this standard is to provide baseline requirements for the design of mechanical systems that minimize the volume of water required to operate HVAC systems.

    (a) Balance environmental responsibility, resource efficiency, process efficacy, and community sensitivity.

    (b) Support the goal of the development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

    2 Scope:

    2.1 This standard provides baseline criteria that:

    (a) Applies to new buildings and renovation projects (new portions of buildings and their systems) and the surrounding site: a building or group of buildings that utilize a single submittal for a construction permit or which are within the boundary of a contiguous area under single ownership.

    (b) Addresses water use through the concept of water use efficiency implemented during design and construction of residential, commercial, institutional, and industrial projects.

    2.2 The provisions of this standard do not apply to:

    (a) Storm or building wastewater management, except as a means of reducing potable water use.

    (b) Industrial process systems

    2.3 This standard shall not be used to circumvent any safety, health or environmental requirements.
