Santa Fe Climate Zone & Energy Code

Climate Zone: IECC Climate Zone 5B (cold-dry). Santa Fe's 7,200-foot elevation produces significant altitude derating (~77% of sea level), very low humidity, intense solar radiation, hot afternoons, and cold nights — a challenging high-altitude high-desert climate profile.

Energy Code & Manual J Requirement: New Mexico Energy Code (IECC 2021). ACCA Manual J required for Santa Fe County HVAC permits. High-altitude construction often incorporates passive solar design and high-performance envelopes that significantly affect Manual J inputs.

Local Electric Utility: PNM (Public Service Company of New Mexico)

Building Department: City of Santa Fe Community Development Department

Local Trade Association: ASHRAE New Mexico Chapter
