（取代ANSI/ASHRAE标准62.2-2004）包括附录C1中列出的ANSI/ASHRAE附录。目的本标准定义了机械和自然通风系统的作用和最低要求，以及旨在为低层住宅建筑提供可接受室内空气质量（IAQ）的建筑围护结构。2.范围本标准适用于单户住宅和地面以上三层或三层以下的多户结构内供人类居住的空间，包括人造房屋和模块化房屋。本标准不适用于临时住房，如酒店、汽车旅馆、养老院、宿舍或监狱。2.1本标准考虑了可能影响空气质量的化学、物理和生物污染物。本标准不包括热舒适性要求（见ANSI/ASHRAE标准55-2004，人类居住的热环境条件）。 2.2虽然可接受的室内空气质量是本标准的目标，但即使满足所有要求，也不一定能达到。由于室内空气来源和污染物的多样性以及人群的易感性范围；b、 由于许多其他因素可能会影响乘客对室内空气品质的感知和接受，例如空气温度、湿度、噪音、照明和心理压力；c、 如果环境空气不可接受，且该空气未经清洁就进入建筑物（本标准不要求清洁环境室外空气）；d、 如果系统未按设计进行操作和维护；当高污染事件发生时。2.3本标准不涉及无通风燃烧空间加热器。本文件的西班牙文译本目前仅在2007年版中提供。

(Supersedes ANSI/ASHRAE Standard 62.2-2004)Includes ANSI/ASHRAE addenda listed in Appendix C1. PURPOSEThis standard defines the roles of and minimum requirements for mechanical and natural ventilation systems and the building envelope intended to provide acceptable indoor air quality (IAQ) in low-rise residential buildings.2. SCOPEThis standard applies to spaces intended for human occupancy within single-family houses and multifamily structures of three stories or fewer above grade, including manufactured and modular houses. This standard does not apply to transient housing such as hotels, motels, nursing homes, dormitories, or jails.2.1This standard considers chemical, physical, and biological contaminants that can affect air quality. Thermal comfort requirements are not included in this standard (see ANSI/ASHRAE Standard 55-2004, Thermal Environmental Conditions for Human Occupancy).2.2While acceptable indoor air quality is the goal of this standard, it will not necessarily be achieved even if all requirementsare meta.because of the diversity of sources and contaminants in indoor air and the range of susceptibility in the population;b.because of the many other factors that may affect occupant perception and acceptance of IAQ, such as air temperature, humidity, noise, lighting, and psychologicalstress;c.if the ambient air is unacceptable and this air is brought into the building without first being cleaned (cleaning of ambient outdoor air is not required by this standard);d.if the systems are not operated and maintained as designed; ore.when high-polluting events occur.2.3This standard does not address unvented combustion space heaters.The Spanish translation of this document is currently available in the 2007 edition only.
