As a result of this proposal approval the 2015 international energy conservation code iecc includes new language that provides unambiguous direction on how the energy code provisions apply to roof repair roof recover and roof replacement. R value based method of section c402 1 3 u c and f factor based method of section c402 1 4. Or component performance alternative of section c402 1 5 roof solar reflectance and thermal emittance fenestration in building envelope. The iecc 2015 and ashrae 90 1 2013 have the most stringent envelope requirements based on conditioned space and non residential space.

Average wall and roof u factor 0 200 in climate zones 1 5 and 0 120 in climate zones 6 8 comply with the roof solar reflectance and thermal. The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures. In previous versions of the iecc code and ashrae 90 1 standard it was easier to obtain lower insulation values in the roof and walls of metal buildings.

Iecc 2015 and ashrae 90 1 2013 have the most stringent envelope requirements based on conditioned space and non residential space this means that for the most part contractors will need to use banded liner systems or long tab banded systems in order to meet the stricter insulation requirements. 877 775 1769 hunterpanels com 0716 iecc 2015 sec.
