Building Performance + HVAC Conferences Happening in 2026 Brit Heller The work of making buildings more efficient, comfortable, and resilient doesn’t happen in isolation. In-person events and conferences remain the most direct way to see what’s actually working in the field – new equipment innovations that solve old problems, code changes that affect your projects, and conversations with the people who’ve already figured out what you’re trying to solve.
