Consensus requires that allviews and objections be considered, and that an effort be made toward their resolut

7、ion.” Compliance with this Standard is voluntary until and unless a legal jurisdictionmakes 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 P

Specific informationon the conten

27、ts of each addendum and approval dates foraddenda are included in Informative Appendix K.First published in 1973 as Standard 62, Standard 62.1 isupdated on a regular basis using ASHRAEs continuousmaintenance procedures. Addenda are publicly reviewed,approved by ASHRAE and ANSI, and published as a su

28、pple-ment at approximately 18 months. The complete collection ofaddenda to the standard are incorporated into the currentedition and published as a new edition every three years.Standard 62.1 has undergone key changes over the years,reflecting the ever-expanding body of knowledge, experience,and res

29、earch related to ventilation and air quality. While thepurpose of the standard remains unchangedto specify mini-mum ventilation rates and other measures intended to provideindoor air quality (IAQ) that is acceptable to human occu-pants and that minimizes adverse health effectsthe means ofachieving t

30、his goal have evolved. In its first edition, the stan-dard adopted a prescriptive approach to ventilation by speci-fying both minimum and recommended outdoor airflow ratesto obtain acceptable indoor air quality for a variety of indoorspaces. In its 1981 edition, the standard reduced minimumoutdoor a

31、irflow rates and introduced an alternative perfor-mance-based approach, the Indoor Air Quality Procedure,which allowed for the calculation of the amount of outdoorair necessary to maintain the levels of indoor air contami-nants below recommended limits. Today, the standardincludes three procedures f

32、or ventilation design, the IAQ Pro-cedure, the Ventilation Rate Procedure, and the Natural Venti-lation Procedure.In its 1989 edition, in response to a growing number ofbuildings with apparent indoor air quality problems, the stan-dard increased minimum outdoor airflow rates significantlyand introdu

33、ced a requirement for finding outdoor air intakeflow requirements for multiple-zone recirculating systems. The 1999 and 2001 editions made several minor changesand clarifications that did not impact the minimum requiredoutdoor airflow rates. The 2004 editionthe last time thestandard was revised in i

34、ts entiretymodified the IAQ Proce-dure to improve enforceability, but more significantly it modi-fied the Ventilation Rate Procedure, changing both theminimum outdoor airflow rates and the procedures for calcu-lating both zone-level and system-level outdoor airflow rates.The 2007, 2010, and 2013 edi

35、tions of the standard providedsome significant updates, but the changes primarily focusedon usability and clarity.The 2016 edition revises and improves the standard inseveral ways. Scope was changed to remove residential occu-pancies from 62.1 with a concurrent change in 62.2 to add allresidential s

36、paces. Significant changes include the following: Previously, Standard 62.1 had responsibility for multi-family residential buildings that are 4 stories or more.Now the dwelling units themselves are covered by Stan-dard 62.2 regardless of building height, while commonareas are covered by Standard 62

37、.1. The definition of “environmental tobacco smoke” (ETS)was revised to include emissions from electronic smokingdevices and from smoking of cannabis. Operations and maintenance requirements were revisedto closer align with the requirements in ASHRAE/ACCAStandard 180-2012. Requirements were added to

38、 the Indoor Air Quality Pro-cedure for determining minimum ventilation rates byincluding consideration of the combined effects of multi-ple contaminants of concern on individual organ sys-tems.
