Four-day conference to convene over 1,200 global experts for decarbonization strategies, networking, and site tours

The International District Energy Association (IDEA) has announced that registration is open for CampusEnergy2026, its 39^th annual campus energy conference, to be held February 17-20, 2026, at the Gaylord National Resort and Convention Center in Washington, D.C.

More than 1,200 energy professionals, policymakers, and technology innovators are expected to attend the four-day event, which will spotlight district energy, microgrids, and thermal energy networks as essential tools for decarbonization at scale.

The 2026 theme, “Advancing Thermal Networks,” will showcase how campuses—from universities to airports—are deploying innovative technologies to reduce emissions, improve efficiency, and strengthen resilience. Attendees will gain firsthand insights through over 100 technical sessions, site tours, expert panels, and hands-on workshops.

“CampusEnergy2026 is about putting ideas into action,” said Rob Thornton, president and CEO of IDEA. “It brings together energy managers, city leaders, and innovators who are delivering real solutions to today’s climate and infrastructure challenges. Hosting in Washington, D.C.—a city long served by district energy—provides a fitting backdrop for global conversations on decarbonization, technology innovation, and resilient infrastructure.”

The four-day conference will feature over 100 technical sessions, hands-on workshops, and case studies from campuses, military bases, airports, and cities, along with networking opportunities for end-users, policymakers, and providers. This year’s program will also include the Patti Wilson Program, honoring the legacy of a trailblazer in district energy by featuring and supporting the next generation of women leaders in the energy industry. Through this initiative, IDEA is proud to elevate emerging voices and foster a more diverse, inclusive future for the sector.
