“In May 2017, Santa Clara, California, became the first city in the world to include ZNE requirements in its building code, requiring all new single-family residential construction to be ZNE. Cambridge, Massachusetts, plans to follow Santa Monica’s footsteps with goals to phase in ZNE in all new construction between 2020 and 2030 starting with commercial buildings and finishing with energy intensive laboratories. These moves follow statewide goals set in 2007 by the California Public Utilities Commission (CPUC) for all new residential construction to be ZNE by 2020 and all new commercial construction to be ZNE by 2030. Many other cities like Fort Collins, Colorado, and Austin, Texas, have also made ZNE plans and goals.
On the national level, the New Buildings Institute (NBI) estimates that the number of “ZNE certified and emerging projects” increased by 74% in 2016 alone.”
