27、 in designing and constructing residential buildings that comply with ASHRAE Standard 62.2-2016, Ventilation and Acceptable Indoor Air Quality in Residential Buildings. Standard 62.2 is written in mandatory language in order to be enforceable as a code, except for one informative appendix. This user

28、s manual does not reproduce the text of the standard, but, rather, is a basic volume of knowledge and facts relating to meeting the provisions set forth in Standard 62.2. A person serious about effectively designing, constructing, and regulating buildings and structures included in the scope of ASHR

29、AE Standard 62.2 will find the users manual to be a reliable source of relevant data and reference materials. The manual is intended to be used in conjunction with the standard and not as a substitute. This document is advisory only. Ultimately the users manual benefits the occupants and owners of d

30、welling units. It is important to understand that ASHRAE Standard 62.2-2016 is a minimum requirement standard. Thus, if an organization or program is adhering to the standard, ventilation of equal or greater airflow rates than the standard requires may be installed but not ventilation airflow rates

31、less than specified. Standard 62.2 was originally published in 2003. This users manual applies to the version of the standard published in 2016, which is known as ASHRAE Standard 62.2-2016. When using this manual to comply with any codes based on Standard 62.2, check to confirm that the code is base

32、d on the 2016 version. If the code is based on a version of 62.2 other than the 2016 edition, this manual might not apply to certain provisions. Audience This users manual is intended to aid many types of residential building professionals, including the following: Builders Code officials Weatheriza

33、tion Assistance Program staff Home performance contractors Home Energy Rating System (HERS) raters HVAC technicians and contractors Design professionals It may also be useful for the following: Governmental agencies Utility program stakeholders Affordable housing stakeholders Property owners and man

34、agers Real estate agents v i Preface Home appraisal professionals Homeowners Addenda Standard 62.2 is a dynamic document that is maintained and updated by ASHRAE under “continuous maintenance” procedures. Periodically, ASHRAE will develop and publish addenda that modify or add to the standard. ASHRA

35、E publishes a full, updated version of the standard on a three-year cycle, which includes all the addenda that have been approved since the previous publication. Between the published versions of the standard, ASHRAE publishes a supplement, which contains any addenda approved during the first 18 mon

36、ths of the three-year revision cycle. Official Interpretations of the Standard In addition to addenda, ASHRAE periodically publishes official interpretations of the standard. Interpretations do not change the standard, but are intended to clarify the meaning of existing provisions. Anyone may submit

37、 a request for interpretation to ASHRAE. Interpretations are limited to the meaning of the standard and may not be used for design reviews or requests for changes to the standard. Requests for interpretation should be sent to: Manager of Standards ASHRAE 1791 Tullie Circle, NE Atlanta, GA 30329-2305

38、 When a copy of the standard is purchased, all interpretations that apply to the standard are included in the package. The ASHRAE website also lists interpretations, and users can check there for any interpretations that may have been issued since they purchased the standard. Previous interpretation

39、s are posted on the ASHRAE website, at www.ashrae.org/standards-research-technology/standards-interpretations Errata for the ASHRAE Standard 62.2-2016 can also be found on the ASHRAE website. Where appropriate, published errata have been incorporated into this users manual, with explanation. Organiz

40、ation This users manual is organized to follow the organization of the standard. Each section of this users manual contains explanatory material intended to assist the user in understanding the provisions of the standard and how to comply with them. Many sections also include examples that give spec

41、ific means of complying with the standard. Some sections also include background material that explains why the standard includes particular requirements, how equipment tests are performed by the manufacturer or testing organizations, or theoretical information intended to provide a deeper understan

42、ding of the provisions and means of compliance. Standard 62.1 Users Manual vii Comments and recommendations are encouraged. Through input from the user, we can improve future editions. Please direct your comments to the manager of standards, as noted above. Acknowledgments The 2016 edition of the St

43、andard 62.2 Users Manual is based on content originally developed for the 2010 edition authored by Roger Hedrick of NORESCO. The 2016 version was developed by Rick Karg of R.J. Karg Associates and member of 62.2 committee; Dr. Charlie Holly of Residential Energy Dynamics; Paul Raymer of Heyoka Solut

44、ions and member of 62.2 committee; and Paul Francisco of the University of Illinois, chair of the 62.2 committee under contract to ASHRAE. The illustrations were created by Joe Medosch of Energy and Environmental Consulting. Substantial contributions were also made by members of the Project Manageme

45、nt Subcommittee chaired by Mike Blanford, U.S. Department of Housing and Urban Development; Michael Lubliner, Washington State University Energy Program; Darren Meyers, P.E., International Energy Conservation Consultants; Dr. Iain Walker, LBNL; and John Dunlap, Dunlap contains irritating contaminant

46、s, such as pollen or other allergens; or contains contaminants at concentrations that might have harmful health effects. Unacceptable indoor air can have one, two, or all three of these characteristics. It might have odors only, but not be unhealthy, or it might be air that seems healthy, but contai

47、ns dangerous concentrations of toxic chemicals that cannot be sensed by the occupants. In summary, the Purpose states that the standard prescribes mechanical ventilation, building envelope recommendations, and other measures intended to provide residential indoor air quality that is acceptable for h

48、uman health and comfort. 2. Scope Changes to 2, Scope 2 Scope. In the 2016 standard “. . . three stories or fewer above grade. . .” was deleted, changing the scope of the standard to include dwelling units in multifamily buildings of any height. Standard 62.1-2016 addresses spaces other than dwellin

49、g units in residential occupancies in multifamily buildings, such as corridors, mechanical rooms, and garages. 2.3. Section 2.3 was deleted in the 2016 Standard, which stated “This standard does not address unvented combustion space heaters.” As determined appropriate, provisions addressing unvented combustion space heaters will be considered in future editions. For the specific addenda that define the differences between the
