The standard has undergone key revisions over the years, reflecting the expanding knowledge, experiences and research related to ventilation and air quality. The standard is updated regularly by the ASHRAE Standing Standard Project Committee and has been revised every three years since 2001. Going far beyond the minimum requirements, it provides information and tools building designers can use to achieve IAQ sensitive building design integrated with other design goals, budget constraints and functional requirements.ĪSHRAE Standard 62 has served as one of the most prominent ventilation standards since it was first published in 1973. The guideline covers design, construction and commissioning of IAQ. It provides information on how to use and apply Standard 62.1 with practical examples of compliance and explains the basis of ventilation rate requirement and calculation methods. The user manual contains explanatory material, detailed information, figures and examples to aid user in designing, installing and operating buildings. The user's manual is intended to be used as a companion to Standard 62.1, which is written to be code enforceable and therefore contains only mandatory language. ASHRAE 62.1-2016 includes appendix A through K, with only Appendix A and B being normative appendices and part of the standard. Informative appendices are merely intended to provide knowledge with no conformance requirements. Normative appendices are part of the standard and provide alternative procedures for compliance to the standard. Portions of this standard, such as ventilation rate tables and formulas, have already been incorporated into some of the model building codes such as international mechanical code and thus become mandatory requirements.Īppendices include two types: normative appendices and informative appendices. The standard by itself is not a code nor it is enforceable, unless it has been adopted or referenced by an authority having jurisdiction. The standard itself has been written in mandatory and enforceable language since 1999. There are many ways to improve indoor air quality, including source contaminant control, keeping HVAC systems clean, filtration systems and increased ventilation rates.ĪSHRAE Standard 62: Ventilation for Acceptable Indoor Air Quality and its subsequent incarnations as Standard 62.1 (commercial and institutional) and Standard 62.2 (residential), serves as one of the most prominent ventilation standards and sets up the minimum ventilation requirements to provide IAQ that is acceptable to human occupants to minimize adverse health effects.ĪSHRAE Standard 62.1 includes four separate parts. Numerous studies spanning several decades have documented the adverse health effects associated with indoor air pollution, ranging from minor discomfort, decreased worker productivity, to respiratory illness and even cancer. Conditioning outside air for ventilation is a big contributor to energy use in a building and is one of the primary factors in achieving sustainable and integrated design. All building components, including envelope, lighting, HVAC system, building automation and controls, outside air treatment and domestic water heating play a role in creating a sustainable environment.
