The 2012 IECC: A “Whole House” Approach to Efficiency Top Ten 2012 IECC residential requirements 1. Mandatory whole-house pressure test aka: Blower Door test CZ1-2 Test out at less than 5 ACH50 CZ 3-8 Test out at less than 3 ACH50 2. More stringent duct leakage test aka Duct Blaster test 3. Steel Framing – equivalency charts adjusted for thermal bridging (see Table) 4. Floor insulation must maintain (continuous) permanent contact against subfloor 5. Low-e essentially required for all CZ’s. Top Ten 2012 IECC residential requirements 6. Wood-burning fireplaces shall tight-fitted 9. Hot water piping must now be insulated flue dampers and outdoor combustion air. to at least R-3 with some exceptions. 7. Whole house ventilation system required • • meet IMC or IRC minimum efficacy 8. 75% of lamps in permanently installed fixtures shall be high efficacy lamps 10. Hard Ducted returns: Building cavities are not allowed to be used as return ducts Top Ten 2012 IECC commercial changes from 2009 1. Vertical fenestration maximum: CZ7-8 30%; CZ 1-6 Still 40% if half the conditioned floor is in a daylight zone; controls are installed; VT/SHGC ratio is at least 1.1 2. Increased Skylight area from 3% max to 5% - with daylighting controls 3. Air barrier – continuous throughout envelope CZ 4-8 4. Pipe insulation more stringent – now also rely on diameter and fluid temp 5. Requires one of these additional efficiency features to be selected for compliance: high-efficiency HVAC; reduced LPD Renewable energy. Top Ten 2012 IECC commercial changes from 2009 6. Air economizers are required in more 10. Calculation of heating and cooling load: climate zones and at a lower threshold (33K must account for building envelope, lighting, Btu/h vs. previous 54K) ventilation, and occupancy-related loads of the project. ASAHRAE/ACCA Standard 183 7. Lighting power limits based on 90.12012 and ASHRAE design conditions space by space method. 8. Commission plan – by a registered design professional (or agency) 9. Cool roofs - minimum solar reflectance and thermal emittance of roofs in Climate Zones 1-3 that have a slope less than 2 in 12 (several exceptions) THE 2012 IECC As Seen By The Us Department Of Energy: The 2012 IECC “represents the largest, one-step efficiency increase in the history of the national model energy code.” In fact, DOE found that the 2012 IECC represents a whopping 32% improvement in US energy savings over the 2006 IECC.

Habitat for Humanity: If home buyers pay less for energy, they can afford larger mortgages. Because energy efficient homes have lower and more stable utility costs, there is less risk of foreclosure. Energy efficiency is a great investment for home owners. When added to a mortgage, energy improvements usually cost less than the savings they offer on utility bills. Increasing the value of a home is a great investment . . . paying high energy bills is not! THE IECC IS THE ONLY I-CODE THAT PAYS FOR ITSELF . . . . . .
