5、ional Standard (ANS) is a national voluntary consensus standard developed under the auspices of ASHRAE.Consensus is defined by the American National Standards Institute (ANSI), of which ASHRAE is a member and which has approved thisstandard as an ANS, as “substantial agreement reached by directly an

6、d materially affected interest categories. This signifies the concurrenceof more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that aneffort be made toward their resolution.” Compliance with this standard is voluntary until

7、 and unless a legal jurisdiction makes compliancemandatory 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

8、 of writing the Standard. The ProjectCommittee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, allmust be technically qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all ProjectC

9、ommittees.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, ord. permission to reprint portions of the Standard.DISCLAIMERASH

Unresolved objec-tors on informative material are not offered the right toappeal at ASHRAE or ANSI.)FOREWORDThis addendum separates vertical air stratification limitsfor standing vs.

21、seated occupants because the previousrequirement did not distinguish between the two and would beoverly restrictive when applied to standing occupants. Thisclarification only applies to occupants who are standing stillwith metabolic rates less than 1.3 met because the entire Sec-tion 5.3.4, “Local T

22、hermal Discomfort,” does not applyabove 1.3 met.Note: In this addendum, changes to the current standardare indicated in the text by underlining (for additions) andstrikethrough (for deletions) unless the instructions specifi-cally mention some other means of indicating the changes.5.3.4.4 Vertical A

27、TAL IMPACT OF ITS ACTIVITIESASHRAE is concerned with the impact of its members activities on both the indoor and outdoor environment. ASHRAEsmembers will strive to minimize any possible deleterious effect on the indoor and outdoor environment of the systems andcomponents in their responsibility whil

28、e maximizing the beneficial effects these systems provide, consistent with acceptedstandards 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 the indoor andoutdoor environment to a greater extent than specified by

29、 the standards and guidelines as established by itself and otherresponsible 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

30、 those newand revised standards developed by other responsible organizations.Through its Handbook, appropriate chapters will contain up-to-date standards and design considerations as the material issystematically revised.ASHRAE will take the lead with respect to dissemination of environmental inform

31、ation of its primary interest and will seekout and disseminate information from other responsible organizations that is pertinent, as guides to updating standards andguidelines.The effects of the design and selection of equipment and systems will be considered within the scope of the systemsintended

32、 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 energy s

33、ource and energytransportation will be considered where possible. Recommendations concerning energy source selection should be made byits members. ASHRAE (www.ashrae.org). For personal use only.
