6、pices of 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 tha
7、n 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. AS
8、HRAE 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 memb
9、ers 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 Senior Manager of Standards of ASHRAE should be contacted fora.

27、TIVITIESASHRAE is concerned with the impact of its members activities on both the indoor and outdoor environment.ASHRAEs members will strive to minimize any possible deleterious effect on the indoor and outdoor environment ofthe systems and components in their responsibility while maximizing the ben
28、eficial effects these systems provide,consistent with accepted Standards and the practical state of the art.ASHRAEs short-range goal is to ensure that the systems and components within its scope do not impact theindoor and outdoor environment to a greater extent than specified by the Standards and G
29、uidelines as established byitself 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 promotethose new and revise
30、d Standards developed by other responsible organizations.Through its Handbook, appropriate chapters will contain up-to-date Standards and design considerations as thematerial is systematically revised.ASHRAE will take the lead with respect to dissemination of environmental information of its primary
31、 interest andwill seek out and disseminate information from other responsible organizations that is pertinent, as guides to updatingStandards and Guidelines.The effects of the design and selection of equipment and systems will be considered within the scope of thesystems intended use and expected mi
32、suse. The disposal of hazardous materials, if any, will also be considered.ASHRAEs primary concern for environmental impact will be at the site where equipment within ASHRAEs scopeoperates. However, energy source selection and the possible environmental impact due to the energy source andenergy tran
33、sportation will be considered where possible. Recommendations concerning energy source selectionshould be made by its members. ASHRAE (www.ashrae.org). For personal use only.
