Net Zero Ready
A Net Zero Ready home is built to the same envelope and mechanical-system quality as a Net Zero home but does not yet have its onsite renewable-energy system installed. The owner can add solar PV later — when budget, roof orientation, or grid policies are favorable — and the home becomes Net Zero. The Department of Energy Zero Energy Ready Home (ZERH) certification formalizes this idea: high-performance envelope, all-electric ready, with a clear pathway to onsite energy.
