Zero energy homes produce at least as much energy as they consume through a combination of energy efficiencies, passive design and renewable energy production. California has adopted zero net energy as the new residential standard for 2020; many other governments are considering similar policies. Developing zero energy homes is the first step towards making all buildings zero energy — a critical step in mitigating climate change, since buildings account for 40% of material and energy use worldwide.
