According to a Report by the U.S. Green Building Council (USGBC), based on research conducted by Booz Allen Hamilton, the green building sector is outpacing overall construction growth in the United States and accounted for more than 2.3 million U.S. jobs in 2015.

The “2015 Green Building Economic Impact Study” found that the green building industry currently contributes more than $134 billion in labor income to U.S. workers.

By 2018, according to the study, green construction will account for more than 3.3 million jobs—more than one-third of the entire U.S. construction sector—and will generate $190 billion in labor earnings. The industry’s direct contribution to the U.S. gross domestic product (GDP) is expected to reach $303.5 billion from 2015 to 2018.

“Green building is playing a massive role in the U.S. construction sector, the clean and efficient sector, and the U.S. economy as a whole,” said Rick Fedrizzi, CEO and founding chair of the USGBC. “Demand for green building will only continue to grow as individuals, businesses and institutions continue to prioritize sustainable approaches to the design, construction and operations of our built environment.”

The new study also explored the multifaceted economic contribution of green construction to the U.S. economy, such as quantifying the economic impact of green building and, specifically, Leadership in Energy and Environmental Design (LEED).

“Our research shows that green building has created millions of jobs and contributed hundreds of billions of dollars to the U.S. economy, with the construction of LEED-certified buildings accounting for about 40 percent of green construction’s overall contribution to GDP in 2015,” said David Erne, a senior associate at Booz Allen Hamilton. “The industry is certainly on the rise, and aggressive growth in the green-building sector is anticipated over the next four years.”

Earnings related to LEED building construction projects in all 50 states are estimated to total $8.4 billion by 2018. In Texas alone, according to the report, approximately 1.25 million jobs in the green-building sector are projected between 2015 and 2018.

Overall, green building will also contribute to significant savings across energy, trash, water and maintenance costs.

The report, of course, bodes well for electrical contractors who specifically market to the green-building sector or work on LEED projects.
