New Filters Before Occupancy

NC-2009 IEQc3.2: Construction IAQ management plan - before occupancy

Susan Walter HDR LEEDuser Expert 1299 thumbs up June 11, 2014- 8:36 am The MERV rating for IEQc3.1 (which I'm assuming your project is also earning) and this credit is 8. The minimum MERV rating for IEQc5 is 13. Because they aren't the same, they get changed before occupancy. This credit does require a change in filtration media before a flush and I believe most teams use MERV 8 filters. You could do more if you wanted.
