BOULDER, CO—Aiming to reduce energy costs and minimize thecarbon footprint of their buildings, governments, corporations, andhome-builders are pursuing zero energy building(ZEB) solutions. Also called net zero energybuildings, ZEBs bring together existing energy efficienttechnologies to form a high-performance building.

According to a new report from NavigantResearch, worldwide revenue from ZEBs is expected to growfrom $629 million annually in 2014 to more than$1.4 trillion in 2035.

“The global zero energy building market has many pockets ofpotential growth, but challenges remain in defining what exactly aZEB is, as well as raising awareness of the increasingaccessibility of these solutions,” says NoahGoldstein, research director with Navigant Research. “Thestrongest driver for this market is regulation, as policies likethe European Union's Energy Performance of Buildings Directive andCalifornia's evolving Title 24 building code bring ZEB markets intobeing for new commercial, new residential, and retrofittedcommercial spaces.”
