According to CBRE's 2017 National Green Building Adoption Index, which ranks 30 of the largest commercial office markets in the U.S. by the share of green-certified square footage, 38% of all office space in the nation's largest markets were LEED and/or ENERGY STAR certified as of 2016.
This is a slight increase from the 37% reported in 2015, but a huge jump from 2005, when less than 5% of office space was certified. The study excluded buildings and square footage of any office that failed to renew certifications after five years.
The study reported that 22 cities, the District of Columbia, two counties, and two states have implemented laws requiring privately owned buildings to disclose annual energy consumption and publish the resulting data. Most of these policies had not reached their full phase-in of reporting by January 2016, though.
Several cities have experienced an increase in the adoption of environmental building certification after passing benchmarking and transparency laws. After Kansas City’s Green Building Adoption measure was passed, certified green square footage jumped five percentage points, and Atlanta gained five points after adopting energy benchmarking and reporting regulations.
