White Pine, Nevada falls within IECC Climate Zone 5B (Cool - Dry), a heating-dominated region with dry moisture conditions. HVAC contractors working in White Pine must use the official ASHRAE design temperatures of -7°F (99% winter) and 91°F (1% summer) when performing Manual J load calculations. These values represent the outdoor conditions your heating and cooling system must handle 99% and 1% of the year, respectively — ensuring proper equipment sizing without costly over- or under-sizing.
Because Zone 5B is heating-dominated, insulation levels are critical. White Pine homes require a minimum of R-20 wall insulation, R-49 ceiling insulation, and windows with a U-factor of 0.3 or lower per the IECC 2021 energy code.
