Notes: a. Domestic hot water pipe insulation requirements are different between the 2012 and 2015 editions of the IECC.

e. In absence of 2006 IECC code requirements for envelope leakage limit, a 2006 IECC baseline is created based on Mendon et al. 2013. "CostEffectiveness Analysis of the 2009 and 2012 IECC Residential Provisions – Technical Support Document". Pacific Northwest National Laboratory, Richland, Washington. The same leakage limit is used for the HUD cases.

In absence of HUD and 2006 IECC code requirements for duct leakage limit, a baseline is created based on Lucas et al. 2007. “National Energy Savings Potential in HUD-Code Housing from Thermal Envelope and HVAC Equipment Improvements” ASHRAE Transactions 113 Part 2:62-69.

The original IECC prescriptive requirements for ceiling, floor and wall sheathing insulation have been modified in some cases to provide consideration for constraints related to manufactured housing dimensions and construction. Where the IECC prescribes ceiling insulation greater than R-38, a value of R-38 is used; where IECC prescribes floor insulation greater than R-30, a value of R-30 is used and wall sheathing requirements prescribed by the IECC are not considered in this analysis. The lighting baseline is created based on the benchmark defined in the 2014 Building America House Simulation Protocols. Wilson et al. 2014. "2014 Building America House Simulation Protocols". National Renewable Energy Laboratory, Golden, Colorado. 7 3 6B 3
