New California Building Efficiency Standards for 2017

Net ZeroOne Step Closer to Zero Net Energy

The majority of the changes to the standards will apply to single-family and low-rise multifamily buildings. California has set goals that all new residential buildings will be zero net energy (ZNE) by 2020 and new commercial buildings will be ZNE by 2030. In general terms, a ZNE building is one that produces as much energy (generally through onsite renewable energy) as it consumes. Given that 2020 standards are right around the corner, the CEC chose to focus on improving the residential code and making modest improvements to the commercial code under the current update. Today's standards are a great step toward meeting that 2020 goal.
