Consensus is defined by the AmericanNational Standards Institute (ANSI), of which ASHRAE is a member and which has approv

6、ed this Standard as an ANS, as “substantial agreement reached by directlyand materially affected interest categories. This signifies the concurrence of more than a simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that an effort be mad

24、 air quality (IAQ) standard developedspecifically for low-rise residential buildings via the ANSIprocess. It has been maintained using the ANSI and ASHRAEcontinuous maintenance procedures. Readers are encouragedto use these procedures to propose changes to the standard.The committee will consider an

25、d take formal action on everyproposal received. Forms and procedures for submittingchange proposals may be found on ASHRAEs website atwww.ashrae.org or at the end of this standard. When pro-posed addenda are available for public review and whenapproved addenda are published, notices will be publishe

26、d onASHRAEs website. The standard is now published in itsentirety every third year and includes all approved addendaand errata. This procedure allows users to have certaintyabout when the new editions will be published. This 2016 edi-tion incorporates the contents of 17 addenda into the 2013edition,

27、 which were processed by the committee and approvedby ASHRAE and ANSI. For brief descriptions of the addendato ANSI/ASHRAE Standard 62.2-2013, see InformativeAppendix D.Since 2007 extensive experience has been gained in theapplication of this standard due to its adoption by variousbuilding codes and

28、 use in numerous building programs.Additionally, the science regarding indoor air quality and itsrelationship to health has advanced significantly. As such,many clarifications and improvements have been identifiedand incorporated, including through the approved addendafor the 2016 edition. Major cha

29、nges since the 2013 editioninclude two scope changes: the inclusion of unvented spaceheaters as a potential contaminant source that the standardcan address, and the expansion of covered dwellings toinclude all multifamily dwelling units regardless of buildingheight. Other major changes include a de

30、minimus calcu-lated mechanical ventilation rate of 15 cfm to require theinstallation of mechanical ventilation in existing homes(addendum b); a distinction between range hoods and otherkitchen ventilation options (addendum c); a method fordetermining an infiltration credit for horizontally attachedm

31、ultifamily dwelling units (addendum j); and a method fordetermining requirements for a variety of noncontinuousventilation strategies (addendum v). Addendum v also imple-ments a maximum short-term relative exposure limit for thefirst time, in addition to the traditional use of annual dose.As in prev

32、ious editions of this standard, there are threeprimary sets of requirements and a number of secondaryones. The three primary sets involve whole-building ventila-tion, local demand-controlled exhaust, and source control.Whole-building ventilation is intended to dilute the unavoid-able contaminant emi

33、ssions from people, from materials, andfrom background processes. Local demand-controlled exhaustis intended to remove contaminants from kitchens and bath-rooms that, because of their design function, are expected tocontain sources of contaminants. Other source control mea-sures are included to deal

34、 with those sources that can be rea-sonably anticipated to be found in a residence. The standardssecondary requirements focus on properties of specific itemsthat are needed to achieve the main objectives of the stan-dard. Examples include sound and flow ratings for fans, con-trols, and labeling requ

35、irements.This standard does not address specific pollutant concen-tration levels. It also does not address certain potential pol-lutant sources such as contamination from outdoor sources orfrom episodic occupant-controlled events such as painting,smoking, cleaning, or other high-polluting events. Fo

36、r infor-mation on residential ventilation and IAQ beyond the mini-mum requirements contained in this standard, users may wishto consult the companion guideline, which was also devel-oped by the Standard 62.2 committee. ASHRAE Guideline 24-2015, Ventilation and Indoor Air Quality in Low-Rise Resi-den

37、tial Buildings, provides explanatory and educationalmaterial not appropriate for a code-intended standard andaddresses IAQ and ventilation issues where consensus couldnot be achieved for inclusion in the standard.1. PURPOSEThis standard defines the roles of and minimum requirementsfor mechanical and

38、 natural ventilation systems and the build-ing envelope intended to provide acceptable indoor air quality(IAQ) in residential buildings.2. SCOPEThis standard applies to dwelling units in residential occupan-cies in which the occupants are nontransient.2.1 This standard considers chemical, physical,

39、and biologi-cal contaminants that can affect air quality. Thermal comfortrequirements are not included in this standard.Informative Note: See ANSI/ASHRAE Standard 55-2013, Thermal Environmental Conditions for Human Occu-pancy.2.2 While acceptable IAQ is the goal of this standard, it willnot necessar

40、ily be achieved even if all requirements are meta. because of the diversity of sources and contaminants inindoor air and the range of susceptibility in the popula-tion;b. because of the many other factors that may affect occu-pant perception and acceptance of IAQ, such as air tem-perature, humidity,

41、 noise, lighting, and psychologicalstress;c. if the ambient air is unacceptable and this air is broughtinto the building without first being cleaned (cleaning ofambient outdoor air is not required by this standard); d. if the system or systems are not operated and maintainedas designed; ore. when hi

42、gh-polluting events occur.ANSI/ASHRAE Standard 62.2-2016 33. DEFINITIONSacceptable indoor air quality: air toward which a substantialmajority of occupants express no dissatisfaction with respectto odor and sensory irritation and in which there are not likelyto be contaminants at concentrations that

43、are known to pose ahealth risk.air cleaning: the use of equipment that removes particulate,microbial, or gaseous contaminants (including odors) fromair.air, exhaust: air discharged from any space to the outside byan exhaust system.air, indoor: air in an occupiable space.air, outdoor: air from outsid
