Ninety-nine commercial buildings either under construction or recently completed produce as much energy through on-site renewable resources as they use. And more highly efficient buildings are on the way.
This is according to a report from the New Buildings Institute (NBI), Vancouver, Washington, which examines the number, location, costs and design strategies of "zero-energy" commercial buildings and "zero-energy-capable" buildings--which are efficient enough to be zero-energy but lack on-site renewable generation.
"Lofty goals have been set for achieving zero-energy buildings by 2030," said Dave Hewitt, executive director of the New Buildings Institute. "The really good news is extremely-energy-efficient buildings are being demonstrated in a multitude of climates and across building types. This is certainly a good sign for the future of zero-energy buildings."
Commercial buildings consumed roughly 20 percent of all U.S. energy in 2010, said the White House in proposing its Better Buildings Initiative, which aims to make more …
