THE OPPORTUNITY
additional people will live in cities. 1.6 billion By 2030,
will be constructed in cities worldwide.
900 billion ft2 (84 billion m2)
By 2030,
of new and rebuilt buildings

Proposed Definition for Zero Net Energy
• Newly constructed residential and commercial buildings
• One definition of ZNE
• Incorporates the societal value of energy (TDV)
• Must be fail proof – a path for all buildings to meet ZNE
Zero Net Energy – a newly constructed building that meets California
Proposed Definition for Zero Net Energy
Building Energy Efficiency Standards, and the value of on-site, or off-site, renewable energy equals the value of the energy consumed by the building annually.
• Optimizes energy efficiency and demand response (TDV).
Residential Zero Net Energy
• Equates to a CA HERS rating of approximately HERS 30.
Building Energy Efficiency Standards:
• Incorporate on-site renewable energy (TDV valued) to offset remaining energy consumed after efficiency (inexpensive), or • Purchase renewable energy to offset remaining energy consumed after efficiency (expensive).
Renewable Energy Requirement:
• Equates to a CA HERS rating of HERS 0.
