Content | ASHRAE 62-2001 sets guidelines for outdoor air requirements for ventilation and occupancy maxima for different facilities. Adhering to these guidelines should ensure that carbon dioxide levels are maintained less than 1,000 ppm, and that complaints are kept to a minimum. Proper thermostat location and a well-maintained heating, ventilation and air conditioning (HVAC) system should allow for temperatures to be maintained within the thermal comfort range. Operating a building under positive pressure will reduce the infiltration of outside contaminants into a building. Using local exhaust in areas such as copy rooms, chemical storage areas, and print shops can reduce other sources of indoor air contaminants.
