The number of zero net energy (ZNE) commercial buildings is on the rise as more contractors implement high-efficiency heat and power systems and build tighter envelopes. That’s according to a report from the nonprofit New Buildings Institute, which seeks to make commercial buildings more energy efficient. Zero-energy projects use as little energy as possible and compensate for their consumption with energy produced on-site. There were 67 zero-energy commercial buildings in 2017, up roughly 26 percent year over year, with more than 400 projects in the pipeline. The majority of the completed projects are offices, schools, and multifamily residential projects, Construction Dive noted in its analysis of the report.
