California’s Net Zero Energy Building Mandate To Reshape US Construction Industry | CleanTechnica

 California’s recent revisions to Title 24 put in place ambitious
performance goals: all residential buildings must be Zero Net Energy
(ZNE) by 2020, and all commercial buildings must follow suit by 2030.
The code also applies to retrofit projects that pass certain thresholds.
(A ZNE building produces as much energy on-site as it consumes on an
annual basis.) These changes promise to reshape the construction
industry in significant ways — and not just in California. Here’s how.
