  1. Zero Net Energy Homes: Background and Definitions Ted Bardacke Nueva Vista, Santa Cruz Colorado Court, Santa Monica

  3. What Zero Energy is Not? • Not Off the Grid - Utilizes net metering • Not Fossil Fuel-Free - Still might have natural gas or “dirty” electricity • Not Carbon Neutral - emissions still dramatically reduced

  4. What is a Zero Net Energy Home? Greatly reduced needs for energy through efficiency gains, with the balance of energy needs supplied by renewable technologies.

  5. What is “Cost Effective?” • Net cash positive from day one when first costs for energy efficiency and renewables are folded into mortgage. • Annual utility bill savings are greater than the additional monthly mortgage payment needed to pay for energy efficiency and renewable components
