Net Zero Energy
According to the Net Zero Energy Coalition, growth of ZE (Zero Energy) home construction was 75% higher in 2017 than in 2016. While California represents approximately half of all net zero energy homes built in the US, growth is occurring across the country, including Massachusetts, which has a similar top-down approach to the construction process, putting this state in second place in the inventory of zero ready (ZR), near zero (NZ), and ZE inventory.
A ZE home (also referred to as a Zero Energy Building, ZEB) is a home that consumes no more energy than it produces in a year. To achieve this, ZE homes are extremely efficient, leveraging cutting-edge building materials and construction methods, smart thermostats, and energy-efficient appliances to keep the home’s energy consumption as low as possible without seriously inconveniencing the homeowner. ZE homes produce on-site energy from renewable sources. In the residential segment, the most common renewable installed is solar photo voltaic (PV) panels. ZR homes have all of the energy-efficient elements with the exception of on-site energy generation.
For many communities, ZE is an important building block for their climate and sustainability action plans, driving several states and cities to introduce ZE legislation
