SimBuild is the premier US venue for sharing cutting edge research in building performance simulation. The conference features peer-reviewed scientific paper presentations, practitioner case studies, and seminars on a range of building performance simulation topics. IBPSA-USA convened the SimBuild conference every other year from 2004 to 2012 as a forum for sharing information through peer-reviewed papers. From 2014 to 2022, IBPSA-USA  partnered with ASHRAE to co-host a bi-annual conference called Building Performance Analysis Conference and SimBuild. IBPSA-USA returns to hosting SimBuild as an independent conference in 2024.
