6、 of ASHRAE. Consensus is definedby 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 sim

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 obta

26、VIRONMENTAL IMPACT OF ITS ACTIVITIESASHRAE 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 responsibil
27、ity while maximizing the beneficial 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 spec
28、ified by the Standards and Guidelines 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
29、 promotethose new and revised 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 environmenta
30、l information of its primary 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
31、intended use and expected misuse. 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
32、energy source andenergy transportation will be considered where possible. Recommendations concerning energy source selectionshould be made by its members. ASHRAE (www.ashrae.org).
