Overview
Passive solar homes are designed from the ground up to minimize mechanical heating and cooling by capturing winter sun, blocking summer sun, and storing thermal energy in mass materials. They're among the most energy-efficient builds possible — but they require more upfront design precision than conventional homes. The orientation, window placement, overhang depth, and thermal mass specification all interact and must be documented carefully.

Permits & Codes
Passive solar homes meet and typically exceed energy code requirements. Some jurisdictions offer expedited permitting for high-performance buildings. Your energy calculations (Manual J or similar) should be included in your permit application.
FAQ
Well-designed passive solar homes can reduce heating and cooling costs by 50–90% compared to a code-minimum conventional home. The exact savings depend on climate, design quality, and occupant behavior.
Passive solar is most effective in cold, sunny climates (Colorado, Utah, New Mexico, etc.). Cloudy climates need a higher-insulation envelope to compensate for lower solar gain.
Yes — most passive solar homes include a backup system (mini-split, wood stove, radiant) for extended cloudy periods. The system is much smaller than a conventional home requires.
