International Building Performance Simulation Association

What International Building Performance Simulation Association does

International Building Performance Simulation Association (IBPSA) is a global, member-governed non-profit professional association founded in 1985 (first BS conference, Seattle) and headquartered in Atlanta, United States, dedicated to advancing building and environmental performance simulation. Its mission is to improve the design, construction, operation, and maintenance of the built environment through simulation. The association serves researchers, engineers, architects, and graduate students active in building energy modeling, HVAC simulation, daylighting analysis, and indoor environmental quality, as well as corporate and academic organizations engaged in simulation tool development and application.

IBPSA's portfolio is organized around five pillars: (1) the Journal of Building Performance Simulation (JBPS), a peer-reviewed journal published in partnership with Taylor & Francis; (2) the biennial Building Simulation international conference (BS2025 Brisbane, BS2027 Vienna, BS2029 RFP issued March 2026); (3) the ibpsaNEWS newsletter distributed twice yearly to ~5,000 members and the @IBPSAUniversity webinar and YouTube library; (4) an awards and recognition program (Distinguished Achievement, Outstanding Young Contributor, Innovative Application, Godfried Augenbroe PhD Thesis Award, Fellows); and (5) open-source research projects, most notably the BIM/GIS and Modelica Framework (Project 1, 2017–2022) and the Building Optimization Testing Framework (BOPTEST). The association is governed by representatives from 32 regional affiliates covering 48 countries plus 10 At-Large Directors.

Revenue is generated through a subscription-and-event model: annual Supporting Memberships ($70–$120/year depending on JBPS inclusion), Student Supporting Memberships ($30–$80/year), and Corporate Memberships ($750 Standard, $5,000 Gold), supplemented by biennial conference registration, sponsorship, and exhibition fees. Distribution is primarily self-serve via a Wild Apricot membership system, complemented by field/community channels through regional affiliates and co-hosting by regional chapters (e.g., IBPSA-Australasia for BS2025). Endorsing partners include ASHRAE, CIBSE, AIRAH, IKCEST, and WUPEN, with Taylor & Francis as publishing partner and DSquared Consulting among listed corporate sponsors.

Core offering

IBPSA is a non-profit professional association that delivers its mission through tiered membership programs (individual, student, corporate), the peer-reviewed Journal of Building Performance Simulation, a biennial international Building Simulation conference held since 1985, recurring educational webinars hosted on YouTube, a twice-yearly newsletter, a global structure of 32 regional affiliates, and recognition programs including awards, fellowships, student competitions, and travel grants. The association also develops and disseminates open-source research software (BOPTEST, BIM/GIS and Modelica Framework) supporting building and district energy simulation.

Product overview

IBPSA is a global professional association advancing building and environmental performance simulation. Rather than a commercial software product, its portfolio consists of: The Journal of Building Performance Simulation (JBPS), the biennial Building Simulation Conference, the ibpsaNEWS newsletter, IBPSA Educational Webinars (3 series on YouTube), IBPSA Student Competitions and Travel Awards, Achievement Awards (Distinguished Achievement, Outstanding Young Contributor, Innovative Application, Godfried Augenbroe), the IBPSA Fellows distinction program, and research projects including the BIM/GIS/Modelica Framework and BOPTEST. The organization also maintains the IBPSA Publications Repository for conference proceedings. Membership spans 32 regional affiliates representing 48 countries.
