After leading an extensive stakeholder engagement process over the past year and a half, the U.S. Department of Energy (DOE) released its findings in the recently published A Common Definition for Zero Energy Buildings, which states that a Zero Energy Building is “an energy-efficient building where, on a source energy basis, the actual annual delivered energy is less than or equal to the on-site renewable exported energy.”
Green Technologies has been involved with low energy buildings for over 16 years coming from the first Green Building in 2000 which saved 19% energy below ASHRAE Standard 90.1 1989 that year, when we had our first LEED Building in 2002 outside of the United States.
