SI conversions for population density added by the authors of this book (not part of original source). Generar‘ Notes 1. Related Requirements: The rates in this table are based on all other requirements of Standard 62-2003 (with addenda) being met. 2. Smoking: This table appiies to no-smoking areas. Rates for smoking-permitted spaces must be determined using other means. 3. Air Density: Voiumetric airflow rates are based on an air density of 1.2 kgm/m3 (0.075 Ibd t3). which corresponds to dry air at a barometric pressure of 101.3 kPa (1 atm) and an air temperature of 21°C (70°F). Rates may be adjusted for actual density, but such adjustment is not require for compliance with this standard. Defauir Occupant Density: The default occupant density shalt be used when actuai occupant density is not known. Default Combined Outdoor Air Rate (per person): This rate 15 based on the default occupant density. Uniisred Occupancies: if the occupancy category for a proposed space or zone is not listed. the requirements for the listed occupancy category that is most similar in terms of occupant density. activi— ties, and building construction shail be used. 7‘. Residential Facilities, Heaith Care Facilities. and Vehicles: Rates shall be determined in accordance with Appendix E (of Standard 62-2001). item-Specific Notes: A. For high schoo! and college libraries, use values shown for Public Spaces—Libraries. 13. Rate my not be sufficientwhen stored materials inciude those having potentially harmful emissions. C. Rate does not allow for humidity control. Additional ventilation or dehumidification may be required to remove moisture. 0. Rate does not include special exhaust for stage effects. e.g.. dry ice vapors, smoke. .mene TABLE E26 Recommended Ventilation and Exhaust Air Requirements—Low—Rise Residential Part A: Ventilation Air: cfm (Us) Floor Area 0—1 2—3 4—5 am? >7 W (“12) Bedroom Bedrooms Bedrooms Bedrooms Bedrooms (1500 (<139) 30 (I4) 45 (21) 60 (28) 75 (35) 90 (42) 1501—3000 (1391—279) 45 (21) 60 (28) 75 (35) 90 (42) 105 (50) 3001—4500 (2731—418) 60 (28) 75 (35) 90 (42) 105 (50) 120 (57) 4501—6000 (418.1—557) 75 (35) 90 (42) 105 (50) 120 (57) 135 (54) 6001—7500 (557.1»697) 90 (42) 105 (50) 120 (57) 135 (64) 150 (71) 150 (71) 165 (78) 135 (64) 3-7500 (>697) 105 (50) 120 (57) Part 8: Exhaust Air If continuousmlocal ventilation exhaust air flow rates: Kitchen: 5 air changes per hour {based upon kitchen volume) Bathroom: 20 cfm [10 Us] if intermittent-«40ml ventilation exhaust air flow rates: Kitchen: 100 Cfm (50 US) (vented range hood required if exhaust fan flow rate is less than 5 kitchen air Changes per hour) Bathroom: 50 cfrn (25 U5) Source: Reprinted with permission of the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. from AfiHRAE Standard 62.2—2003.
