Greenbuild Comes to New York

For the first time, the Greenbuild International Conference + Expo came to New York City, meeting October 20 to 23, 2026, at the Javits Center. Its theme, “Invest for Impact,” challenged the industry to push harder on decarbonization, resilience and healthier buildings. The venue made the point even before any session began: The campus includes a 6.75-acre green roof with bird habitat and a rooftop farm. The week drew more than 250 exhibiting companies, more than 10,000 attendees and more than 150 CE-accredited sessions on resilience, decarbonization and climate policy.

The main stage set the tone. CNN host Fareed Zakaria opened Wednesday’s keynote with a look at the geopolitical landscape and what it means for building a healthier world. Thursday’s session turned to data centers, with a panel moderated by Lauren Kiel of Bloomberg Media. NYSERDA President and CEO Doreen Harris opened that morning with a host-state welcome on turning “Invest for Impact” into measurable progress.

That focus matched a concern raised by Ben Stapleton, executive director of USGBC California. “It’s really about community,” he said, calling the event a reminder that the work needs a community to carry it. He described climate work as “a long haul” that depends on relationships, and pointed to climate resilience, which he said felt louder this year.

The tours took those themes onto the streets. Attendees could visit the Battery Park City and East Side Coastal Resiliency projects, the passive design of the American Museum of Natural History’s Gilder Center, and the Empire State Building. Hudson Yards, built over active rail yards, was another stop. Walking the High Line, which runs through the neighborhood, was a highlight for many attendees, showing how public green space can anchor a dense urban transformation.

Among the expo’s most distinctive spaces was the Mindful Materials Pavilion, where the nonprofit behind the Common Materials Framework curated a lounge around circularity. Fourteen exhibitors took part, and the furniture on display, from Steelcase to Shaw Contract, was reclaimed or given a second life.

What stood out most on the show floor was the enthusiasm of the booth hosts, who were eager to explain their products and connect with visitors. The energy was palpable and uplifting. Among the exhibits that caught attention was a shipping container converted into a “urine mill,” a sign that resource recovery is moving from concept to hardware.

Books were part of the show floor, too. David Gottfried, a co-founder of USGBC, signed copies of Regen360: An Operating System for a Regenerative Earth on the Expo floor, where the book debuted. Its argument is that green building’s gains haven’t reversed warming or biodiversity loss, and that a new economic operating system is needed.

Stapleton’s emphasis on community and Gottfried’s call for a new system point to the same question: What will sustain this work for decades? New York’s answer was to show projects that already prove the approach.
