Building Science Symposium
Back by popular demand, the Building Science Symposium returns as a pre-IBS 2026 event with fresh content and big ideas. This full-day experience, before the official start of the Builders' Show, is the only place you can dive deep into the science of high performance building with top high performance builders who are putting building science into practice every day.
From the moment you arrive until the day wraps up with a networking happy hour, it's an immersive day of learning, networking and connecting with suppliers who bring building science products and systems directly to you. It's more than a pre-show event, it's a conference within a conference, built around the building science topics that matter most to your business.
This is a pre-show event that requires a separate registration from your IBS registration.
Experience the only event that dives deep into building science — where learning, networking and innovation collide.
