Texas State Building Energy Code Update

Posted By Administration, Tuesday, April 14, 2020
Updated: Wednesday, April 8, 2020

PIMA’s State Energy Code Fact Sheets provide a state-by-state detail of the minimum insulation requirements for low-slope commercial roofing in both new and existing buildings. Each fact sheet includes state-specific insulation requirements, code-compliant assembly examples, and links to helpful resources. PIMA monitors state codes regularly to provide the most up to date information possible.

The 2015 International Energy Conservation Code reviews the energy-efficiency requirements for commercial building roofs in Texas. The minimum requirement for insulation installed entirely above the roof deck is R-25 for climate zones 2 and 3, and R-30 for climate zone 4. This code became effective on November 1, 2016.

 Sample roof assembly diagrams and additional information can be found in PIMA’s Texas code fact sheet.
