Heat Recovery and 2009 IECC

New postby mtCDCcb on Wed Jan 07, 2015 6:55 pm

Posted this a few weeks and didn't hear back so giving it one more shot.
We have a 4 story 44 Unit condo complex (R-2 Occupancy). The common halls have an existing separate ventilation system. Does the 2009 IECC require individual HRV units for each condo? Does it even require one for the building. We are in climate zone 7. My initial research indicates no but wanted to double check. Thanks.

I was out up in New York state doing some expert witness investigations and missed your first post - my apologies.

You mentioned "existing", when was the structure built? The International Existing Building Code (IEBC) would be the first code to be applicable, and if it was permitted as it is existing, the Existing Building Code would not require changes in and of itself.

If sufficient work was being done, then the IEBC may refer back to the IEEC for the work area of the new work.

There was a major water leak there this spring. The place has been completed gutted and its being remodeled. So new insualtion, drywall etc. The only difference than from before is the individual unit floor plans are slightly changing.
