SPECIAL NOTE
This American National Standard (ANS) is a national voluntary consensus standard developed under the auspices of the American
Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Consensus is defined by the American National Standards
Institute (ANSI), of which ASHRAE is a member and which has approved this standard as an ANS, as “substantial agreement reached by
directly and materially affected interest categories. This signifies the concurrence of more than a simple majority, but not necessarily unanimity.
Consensus requires that all views and objections be considered, and that an effort be made toward their resolution.” Compliance with this
standard is voluntary until and unless a legal jurisdiction makes compliance mandatory through legislation.
ASHRAE obtains consensus through participation of its national and international members, associated societies, and public review.
ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the Standard. The Project
Committee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, all
must be technically qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all Project
Committees.
The Manager of Standards of ASHRAE should be contacted for:
a. interpretation of the contents of this Standard,
b. participation in the next review of the Standard,
c. offering constructive criticism for improving the Standard, or
d. permission to reprint portions of the Standard.

POLICY STATEMENT DEFINING ASHRAE’S CONCERN
FOR THE ENVIRONMENTAL IMPACT OF ITS ACTIVITIES
ASHRAE is concerned with the impact of its members’ activities on both the indoor and outdoor environment. ASHRAE’s
members will strive to minimize any possible deleterious effect on the indoor and outdoor environment of the systems and
components in their responsibility while maximizing the beneficial effects these systems provide, consistent with accepted
standards and the practical state of the art.
ASHRAE’s short-range goal is to ensure that the systems and components within its scope do not impact the indoor and
outdoor environment to a greater extent than specified by the standards and guidelines as established by itself and other
responsible bodies.
As an ongoing goal, ASHRAE will, through its Standards Committee and extensive technical committee structure,
continue to generate up-to-date standards and guidelines where appropriate and adopt, recommend, and promote those new
and revised standards developed by other responsible organizations.
Through its Handbook, appropriate chapters will contain up-to-date standards and design considerations as the material is
systematically revised.
ASHRAE will take the lead with respect to dissemination of environmental information of its primary interest and will seek
out and disseminate information from other responsible organizations that is pertinent, as guides to updating standards and
guidelines.
The effects of the design and selection of equipment and systems will be considered within the scope of the system’s
intended use and expected misuse. The disposal of hazardous materials, if any, will also be considered.
ASHRAE’s primary concern for environmental impact will be at the site where equipment within ASHRAE’s scope
operates. However, energy source selection and the possible environmental impact due to the energy source and energy
transportation will be considered where possible. Recommendations concerning energy source selection should be made by
its members.
