Purpose 1.1 Specify minimum ventilation rates  and other measures intended to provide IAQ that is acceptable to human occupants and that minimizes adverse health effects 1.2 Intended for regulatory application  to new buildings and additions 1.3 Guide the improvement of IAQ in  existing buildings 2. Scope 2.1 All spaces intended for human occupancy  excluding low-rise residential (62.2) 2.2 Defines requirements for ventilation, air-cleaning  design, commissioning, installation and O&M 2.3 Additional requirements and other standards  may apply (labs, healthcare, industrial, etc.) 2.4 May be applied to both new and existing  buildings, not intended to be used retroactively 2.5 Does not prescribe specific ventilation rates for  smoking spaces 2. Scope 2.6 Ventilation requirements based on  chemical, physical, & biological contaminants 2.7 Consideration or control of  thermal comfort is not included 2.8 In addition to ventilation, the  standard contains requirements related to certain sources 2. Scope 2.9 Acceptable IAQ may not be  achieved in all buildings meeting these requirements because of: Diversity of sources and contaminants  Air temperature, humidity, noise, lighting,  and psychological/social factors Varied susceptibility in the occupants  Introduction of outdoor contaminants  3. Definitions 36 Terms Defined  Two of Particular Significance  Acceptable Indoor Air Quality  Occupiable Space  General Requirements 4. Outdoor Air Quality 4.1 Regional Air Quality  Must determine NAAQS attainment status  www.epa.gov Air cleaning is required in some cases in  non-attainment areas 4.2 Local Air Quality  Conduct observational  site survey to identify local sources of air contaminants General Requirements 4. Outdoor Air Quality 4.3 Documentation  Regional air quality compliance status  Local survey information  Conclusions regarding  acceptability of outdoor air quality
