Zero Energy Ready Home (ZERH)
A DOE certification for homes so energy-efficient that a standard solar system can offset all or nearly all annual energy consumption. Requires high-performance envelope, HVAC, lighting, and appliances.
Why It Matters
ZERH homes use 40-60% less energy than code-built homes. The IRA provides a $2,500-5,000 tax credit for new homes meeting ZERH standards.

Building Energy Code
Minimum energy efficiency standards for new construction and major renovations, set by states/cities based on IECC or ASHRAE 90.1. Some states now require solar-ready or solar-equipped new homes.
ENERGY STAR
