The Green Innovator

The green innovator promotes LEED across a broad range of projects.

Charlie Cichetti, who’s leading a rolling wave of green innovation, calls his 2008 layoff from his construction job at real estate developer The Opus Group a blessing in disguise. He’d earned his first LEED AP credential that year, and his journey into the world of sustainability was just getting started when the recession hit.


“They laid off the entire construction team,” says the Atlanta-based social entrepreneur. “I was in tears. My wife and I had just bought our first house together; it was the year our first son was born.”

However, his experience at Opus had taught him a lot, and the man who’s gone on to teach tens of thousands of building professionals the best ways to design and build green was ready to expand on it.

“Opus was the developer, the designer, the construction team and the property manager, all in one company,” Cichetti says. “As a young professional, it was an amazing experience. Plus, they were an early adopter of LEED; it’s where I really cut my teeth on LEED projects.”

Back then, those projects were mainly new construction. Today, Cichetti is immersed in the greening of both new and existing buildings—including stadiums and skyscrapers—in Atlanta, across the U.S. and in several other countries.

Cichetti, who was named a LEED Fellow in 2020, says he’s humbled to be among the elite group of 330; each month, he facilitates a Zoom call for the whole group. “We share a common goal that as we make buildings better, we protect the environment,” says Cichetti, who’s the CEO, founder and strategist behind a compelling array of small forces in the green building industry.

His portfolio of businesses includes education and software ventures that are helping propel green building from a specialty endeavor to business as usual.

In 2009, he and a former colleague launched Sustainable Investment Group (SIG)—a full-service consulting, engineering and training firm that was an early force in the real estate movement toward healthy building and wellness. Today, the firm has covered 50 million square feet and completed more than 400 projects, many of which achieved LEED Gold or Platinum status.

SIG has led to three more Cichetti creations that are helping to define sustainability’s potential.

Green Building Education Services, begun in 2007 and taken over by Cichetti in 2014, was the first company to make LEED AP practice tests. Since then, it has grown into a worldwide powerhouse responsible for teaching upwards of 150,000 professionals about green building and helping them to earn and maintain their professional credentials.

Next came the technology startup Blue Ocean Sustainability, a software company that creates solutions for developers and contractors in green building. One of its main tools, TrueCarbon, helps track energy, water and embodied carbon impacts during construction.

During the pandemic, Cichetti says, “We got really innovative in order to keep the business moving.” When his team couldn’t travel, clients at construction sites and energy efficiency projects at existing buildings were supplied iPads for “over the shoulder” work.

That led to the third division under Cichetti’s green-building umbrella, Aetos Imaging, a 3D scanning and digital twin venture that’s able to virtually tell the story of any project’s healthiest, most sustainable possibilities.

“The pandemic sped things up for us,” Cichetti says of his new technology enterprises. “In eight weeks’ time, we built up years of innovation. And I’ve heard the same from other companies.”

He’s proud of 1180 Peachtree Street, which was the first LEED Gold high-rise office building in the southeast U.S. when it was built in 2006. Last year, the SIG project team won a USGBC Georgia Chrysalis Award for the building’s sustainability upgrade to LEED Platinum through its recertification under LEED for Operations and Maintenance.

Upgrading the Hines-owned building meant taking a skyscraper that was built green and figuring out ways it could better operate green. Today nearly 2,000 occupants of the 41-story office tower enjoy enhanced HVAC equipment and clean power. Reserved parking for alternate-fuel vehicles, EV charging stations and secure bike storage, plus incentives for commuting via the nearby train station, contribute to the building’s improved sustainability.

Cichetti and his teams are called on to bring LEED certification to projects of all ages. He embraces the challenge of 30- to 40-year-old buildings in Manhattan, and also cites upgrades to two stadiums in the Twin Cities of Minnesota as LEED achievements in existing buildings.

“New construction is something we do very well,” Cichetti says, but he sees existing buildings as a key part of the movement’s future. “We are very good at applying green practices to any building in existence.”

In 2019, his work took him to the island country of St. Lucia, where green building was virtually unknown until he and his team arrived to assist 34 professionals with earning their LEED credentials. Previously, there were zero. “Helping create new green building careers in St. Lucia was really a career highlight for me,” he says.

To further spread the word about sustainability, Cichetti hosts a weekly podcast called Green Building Matters. His interviews with green leaders help uncover the stories behind the sustainability movement.

When he’s not working, Cichetti spends time with his wife Latrice and their three young sons. He especially enjoys bringing his family to the North Georgia mountains where he was raised. Aside from involvement in his kids’ many activities, Charlie likes to play tennis, read and indulge his love for technology.

LEED is “a tool to make sure we’re all talking the same language,” says the green pioneer. “There’s always more to do,” he says. “But I argue that LEED has created a target for us all to hit. There are so many buildings that may never have improved, but thanks to LEED, they’re achieving a lot more than they ever would have originally.”
