DMV Zero Net Energy Facility in Fresno

Requirements for ZNE

    • Includes all new construction, major renovations and build-to-suit leases that began design after October 23, 2017  

    • 50 percent of existing state building area shall achieve ZNE by 2025

Steps to ZNE

    1. New construction, major renovations and build-to-suit leases shall exceed Title 24, Part 6, Building Energy Efficiency Standards by at least 15%.
    2. Existing state buildings should work to meet or exceed the Source Energy Use Intensity (Source EUI) targets listed under their climate zone in the State of California Energy Efficiency Targets for Existing State Buildings Pursuing Zero Net Energy (ZNE).
      1. Measure energy efficiency
        • Total energy use from all sources (electricity, natural gas, propane, steam, chilled water, etc.) converted into Source kBtu.
        • Does not include energy use from electric vehicle charging, or other types of transportation fuels used.
        • Divide total energy quantity (Source kBtu) by building area (square feet) to obtain Source Energy Use Intensity (EUI).
        • ZNE calculator can help calculate Source EUI.
      2. Compare with energy efficiency targets established for state buildings. Buildings or facilities below the EUI targets are “ZNE ready” and can become ZNE once renewable energy is obtained.
    • a. Provide renewable energy from onsite and/or offsite sources that generates as much clean renewable energy on an annual basis as the building/facility uses during the year.

      1. Preference to onsite generation when possible or feasible to reduce environmental impact.
      2. Offsite generation acceptable from in-state sources, with long-term (20-year minimum) purchase agreement.All Renewable Energy Certificates (RECs) shall be retired on behalf of the state.
