Major Changes In 2012 IECC 1. Increased R-value in exterior walls for most zones was R-13 in climate zone 3 now R-20 2. Maximum air infiltration rate for fenestration reduced for storefront glazing was 0. 3 cfm/ft 2 at 75 Pa now 0. 06 cfm/ft 2 at 75 Pa 3. Maximum area of vertical fenestration reduced from 40% to 30% (certain daylight zones may have 40% max. area) 4. Maximum U-factor fenestration reduced In climate zone 3 was 0. 60 now 0. 46 for fixed glazing Copyright 2008, International Code Council 2

Changes to 2012 IECC continued 5. Air barrier construction identified Fifteen materials are deemed to comply Can be inside or outside of the building thermal envelope 6. Blower test option for Commercial (Required for Residential) 0. 4 cfm/ft 2 at 75 Pa for commercial 7. Blower test required for Residential was 7 ACH at 50 PA now 3 or 5 ACH at 50 PA depending on climate zone Copyright 2008, International Code Council 3

Changes to 2012 IECC continued 8. Duct tests required for Residential only if not entirely within the building envelope (4 cfm per 100 sf of conditioned area at 25 Pa) 9.
