College Station sits in IECC climate zone 2A, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover College Station on this site, so Google Maps supplies the 8 ranked names you see below. Checked September 2026.

College Station's climate zone, in plain terms
College Station falls in IECC climate zone 2A, and ENERGY STAR separately groups Brazos County into its Southern zone for window certification.
Those two numbers, not the brand on the box, set the U-factor and SHGC worth checking on any quote you get in College Station.
A College Station-Bryan, TX contractor who can't name either one on request is worth a second question before you sign.
Data: U.S. EPA / DOE, ENERGY STAR, ENERGY STAR Version 7.0 Climate Zones by County/ZIP (Windows, Doors, and Skylights) (V7.0); Pacific Northwest National Laboratory (DOE Building America), Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270) (2021 IECC), from the nearest NOAA station 4.1 mi away.
