New Green Code Spells out Thermal Requirement for Roof Retrofits

The 2012 International Green Construction Code (IGCC) includes a straightforward approach to minimum thermal requirements for roof and wall systems. In addition, the new code extends the minimum thermal requirements to all low-slope roof replacements involving above-deck insulation. “Our association is impressed that, for the first time, a national energy code makes specific and clear requirements on the thermal performance of a retrofit roof,” said Jared Blum, president of the Polyisocyanurate Insulation Manufacturers Association (PIMA).

The International Codes Council will publish the first edition of the IGCC in the spring of 2012, and it is expected that many state and local governments will quickly adopt the IGCC as the primary benchmark for “green” construction standards and practices. As soon as the IGCC is published, PIMA will offer on its website a roof and wall design guide to complement the code and serve as an easy reference for building professionals designing to the code.
