Determine the required ventilation rates for indoor spaces based on occupancy and space types. ASHRAE 62.1-2004 tables 6-1 and 6-4 list minimum requirements for particular spaces.
Consider whether your HVAC system will be able to power a flush-out while maintaining temperature and humidity levels during seasonal extremes in a timely fashion, without major scheduling impacts. A total of 14,000 cubic feet of outside air must be exchanged for every square foot of floor area. The amount of outside air prescribed during a phased flush-out (0.3 CFM) may be several times greater than the normal rate required for a project’s occupancy, based on ASHRAE 62.1-2004, as required by EQp1: Minimum IAQ Performance.
If you choose to pursue EQc5: Indoor Chemical and Pollutant Source Control, relatively high MERV 13 filtration is required. Pursuing both credits may require you to increase duct size and fan power, and may even affect your system selection.

Interior lighting cannot spill out of the windows after business hours. Window coverings or automatic controls like timers, occupancy sensors, or master switches have to shut off all non-emergency indoor lights during that time.
Be aware of all requirements for interior lights so that fixtures do not direct their maximum candela through windows to the outdoors. Identify locations where fixtures might have a direct line of sight to a window or other opening. The lighting designer should either eliminate those fixtures from the design, provide shades to prevent the maximum candela from shining outdoors, or include controls to turn off all non-
