Reno's climate zone, in plain terms
Washoe County's normal precipitation runs about 8.1 inches a year, with 29.7 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Reno.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Reno buyer benefits from checking both instead of assuming one implies the other.
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 3.2 mi away.
What FEMA's risk data says about Reno
Neither rating changes a window's energy label, but both are exactly what impact-resistance and design-pressure ratings are built to answer for a Reno home.
Ask specifically about design pressure and impact rating for Reno, not just energy performance, if either risk rating comes back on the high side.
- Strong wind
- Relatively Moderate
- Winter weather
- Very High
