Texas SB2102 establishes energy efficiency standards for unvented attics and rafter assemblies in residential buildings.

Texas SB2102 amends the Health and Safety Code to set energy efficiency performance standards for unvented attics and rafter assemblies in residential buildings. The bill specifies that these assemblies must be insulated and air sealed with air impermeable insulation to an R-value of at least 20 in climate zones 2 or 3, and 26 in climate zone 4. Additionally, the building must meet certain criteria, including achieving a blower door test result of less than 3.0 ACH50 and having a mechanical ventilation system that does not rely solely on a negative pressure strategy.
