IRC, not the IECC) • Mandatory whole-house pressure test • More stringent duct leakage test • DHW distribution system requirements – Minor changes – Key non-changes • Retains prohibition on envelope-equipment trade-offs • Makes lighting requirements “mandatory” 2012 IECC Overview – Major Changes For SI: 1 inch = 25.4 mm. 2009 IECC 2012 IECC CHANGES REVISION TYPE 101.2 Scope C101.2 Scope R101.2 Scope The 2012 IECC separated the residential and commercial portions into two distinct, separate, stand-alone “codes.” Both residential and commercial scopes were revised to These solutions do not represent the only compliant options to meet lighting and receptacle control requirements. Residential Energy requirements in the IRC and IECC are now identical; Format has changed. I know this question will apply to a very few engineers and the answer will vary around the country depending on climate zone and codes enforced, but has anyone found a way to get around the economizer requirements in the 2009 or 2012 IECC? 2015 IECC –Option: Prescriptive. Indicate equipment efficiencies, system controls, outdoor-air ventilation rates, duct insulation levels, duct sealing, and water-heating components that comply on your project plans.
