HackSimBuild will take place on May 18-19, 2026, immediately before SimBuild 2026. Participants will present their work to SimBuild attendees and a panel of industry experts during SimBuild 2026.

The program will kick-off with an opportunity for the participants to share quick introductions about their background and interests. This will be followed by a team-forming session to allow participants to pitch their hacking ideas and join teams to collaborate on a common goal for their HackSimBuild project.

Software and building simulation experts will be on hand to help teams realize their idea.

After 24 hours each team will present and demonstrate their project.

Teams will present their projects at the 2026 SimBuild Conference and be judged by a panel of industry experts who will select the winners.

We encourage teams that integrate students, building analysts, designers, architects, engineers, programmers, and other participants. Registrants may form teams in advance or at the event. Teams will have 24 hours to address a building performance simulation challenge of their choosing.

The teams may use any software or a combination of software to complete their projects. Open-source projects are highly encouraged!
