California Green Building Standards Code 2019 > 5 Nonresidential Mandatory Measures > 5.504 Pollutant Control > 5.504.1 Temporary Ventilation
JUMP TO FULL CODE CHAPTER
The permanent HVAC system shall only be used during construction if necessary to condition the building or areas of addition or alteration within the required temperature range for material and equipment installation. If the HVAC system is used during construction, use return air filters with a Minimum Efficiency Reporting Value (MERV) of 8, based on ASHRAE 52.2-1999, or an average efficiency of 30 percent based on ASHRAE 52.1-1992. Replace all filters immediately prior to occupancy, or, if the building is occupied during alteration, at the conclusion of construction.
