Zero Energy Buildings More Than Double Since 2018

The demand for zero energy buildings across the U.S. and Canada is growing, according to new data from New Buildings Institute (NBI), a nonprofit organization pushing for better performance in buildings. NBI unveiled its 2020 Getting to Zero Buildings List, which shows the total number of verified and emerging zero energy buildings in North America has grown to nearly 700 – representing a 42 percent increase since 2018. The total square footage of zero energy buildings has surpassed 62 million, a 39 percent jump from 2018. The number of verified zero energy buildings in the U.S. and Canada more than doubled between 2018 and 2020, a sign that designers are gaining expertise for delivering on zero energy targets set by building owners.

A verified zero energy building is defined as an ultra-low-energy building that consumes only as much energy as it produces with clean renewable energy. These projects must provide 12 months of measured energy use and renewable energy production data. An emerging zero energy building is one that has a goal of achieving zero energy, but has yet to be completed or attain zero energy-level performance.

“In the United States, where buildings are responsible for nearly 30 percent of the nation’s carbon emissions, zero energy buildings will continue to play an important role as we transition to a low-carbon economy,” says Ralph DiNola, CEO of NBI. “Because so many of the zero energy buildings we are tracking run entirely on electricity and include on-site renewable energy generation, they are proving to be a cost-effective way to reduce carbon emissions, achieve deep energy savings, and improve the indoor air quality of homes and commercial buildings.”

2020 Getting to Zero Buildings List Key Findings & Trends

States with climate action goals lead the market. Projects span all climate zones and nearly every state and province. While they are concentrated in California and the Northeastern U.S., zero energy buildings outside these dominant regions grew by more than 20 percent over the last two years. The states with the most growth in zero energy projects over the last two years are California, Oregon, New York and Massachusetts – not surprising given the ambitious climate action goals set by state and local governments in these places.

Both public and private sectors see strong growth. Publicly and privately-owned buildings continue to grow at a similar pace. Despite owning less real estate than private building owners, publicly owned government offices, libraries, schools, and universities make up a significant portion of NBI’s 2020 Getting to Zero Buildings List. In the private sector, several large companies, including IKEA, Walmart, Google, Apple and Amazon, have completed zero energy projects. Many of these corporations have already set or have committed to setting science-based emissions reduction targets. 

Meeting zero energy goals is more attainable than ever. Twenty percent of the buildings on NBI’s Getting to Zero Buildings List are verified – the largest percentage to date – signaling designers are getting better at meeting zero energy project goals. Verified buildings have a median energy use intensity (EUI) of 20 kBtu per square foot per year and consume about half the energy of comparable buildings. The remaining energy demand is met with renewable resources.
