Net-Zero Energy Buildings Double 0

While the total number of net-zero energy buildings remains small, “the growth and diversity are important indicators for what we should expect in the coming years,” notes Ralph DiNola, executive director of New Buildings Institute (NBI), which tracks the growth of these buildings.

“We are seeing this play out in the shift from a handful of projects primarily in the public domain, to private companies such as Walgreens and TD Bank embarking on these building projects and using those experiences to inform future development,” he says.

There are 33 verified net-zero energy buildings in North America and 127 more that await verification after gathering a full year of energy data. 53 other buildings have levels of efficiency comparable to net-zero but don’t have sufficient onsite renewable energy. In all, there are 213 buildings, up from 99 buildings in 2012, according to NBI.

NBI’s report, 2014 Getting to Zero Status Update finds that net-zero energy buildings are:

  • achievable in all regions and climate zones: they are currently in 36 states and two Canadian provinces that cover all eight climate zones.
  • possible in many building types and sizes: current buildings are spread across K-12 schools and universities offices, low-rise apartment buildings and merging labs ratory buildings. Half are over 100,000 square feet.

    Education buildings such as K-12 schools and universities, make up the single largest category this year, with a third of all net-zero buildings. An example is the Center for Energy Efficient Design, a net-zero learning lab  for middle school students in Rocky Mount, Virginia.

  • achievable for retrofits, not just new construction: 24% of this year’s list is for renovation projects
  • net-zero districts are a growing trend: in addition to individual buildings, there is a new trend of communities and campuses committed to groups of net-zero buildings.  NBI identifies 18 Districts, with the U.S. Army and several universities leading.
  • increasing interest from the private sector: 26% of net-zero buildings contructed this year were for private corporations.

Some examples they point to:

Anna Maria Historic Green Village in Florida combines historic preservation – four 100-year-old buildings – with state-of-the-art green technology, bringing jobs and economic development to local residents.

TD Bank‘s retail branch in Fort Lauderdale, Florida.

The Ramona in downtown Portland, Oregon, is a mixed-use development with 138 units of affordable housing and two educational facilities.

Last year, a net-zero energy training center opened San Leandro, California, to teach electricians advanced skills in this area. It’s a joint project of the International Brotherhood of Electrical Workers Local Union 595 and the North California Chapter of the National Electrical Contractors Association.

Here’s the report and a map that shows where the buildings are:
