IBPSA-USA

What IBPSA-USA does

IBPSA-USA (International Building Performance Simulation Association – USA) is a U.S. nonprofit professional association and the official regional affiliate of IBPSA-World. Founded in 2002 and headquartered at 401 Edgewater Place, Wakefield, Massachusetts, the organization is dedicated to advancing and promoting the science of building performance simulation to improve the design, construction, operation, and maintenance of buildings in the United States. Its core constituency comprises energy modelers, building performance analysts, simulation engineers, and related AEC professionals, supplemented by student and early-career members served through the EPSI committee, plus architecture/engineering firms, software vendors, and government research bodies (US DOE, NREL, PNNL) that participate in standards-setting and sponsorship.

IBPSA-USA's substantive outputs are programmatic rather than software products. Flagship offerings include SimBuild (a biennial conference; SimBuild 2026 scheduled for Minneapolis), semi-annual meetings co-located with ASHRAE conferences, the Building Data Exchange (BDE) committee producing tool-agnostic consensus data models, the BEST Directory of building energy software tools, Project STASIO, an Education on Demand video library, an Ask A Modeler expert Q&A column, and a Job Board. The organization supports multiple standing committees (Education, Research, Advocacy, Equalities/DEI, BDE) and a chapter network across the United States. Major strategic partners include IBPSA-World, ASHRAE, the Net Zero Conference, and federal research labs contributing to standards development.

The business model is a member-driven subscription-plus-sponsorship nonprofit. Revenue is generated through three tiered annual membership dues (Premium $100, Basic $50, Student $25), ticket sales for SimBuild and semi-annual meetings (membership confers discounts), and a tiered corporate sponsorship program (Silver, Bronze, Friend) drawing AEC firms and building-simulation technology vendors (Atelier Ten, BetterBuilding, Pollination, HKS, and others in 2026). Distribution is via a self-serve Wild Apricot membership portal, local chapters, and ASHRAE-aligned conference infrastructure; go-to-market is community-led and event-driven, with marketing channels concentrated in a monthly newsletter, a content-rich website, and active social media presence across LinkedIn, Facebook, Twitter, Instagram, and YouTube.

Regional players

• CIBSE (Chartered Institution of Building Services Engineers): CIBSE is the U.K.-based professional body for building services engineers and offers memberships, conferences, and publications comparable to IBPSA-USA. It is a strong analog as a peer association, though focused primarily on the United Kingdom.
• IBPSA-France / other regional IBPSA affiliates: Regional IBPSA affiliates (e.g., IBPSA-France, IBPSA-UK, IBPSA-Australia) replicate IBPSA-USA's model of national simulation community-building in their geographies. They are structurally identical peers outside the U.S.

Broad incumbents

• U.S. Green Building Council (USGBC): USGBC administers LEED certification and convenes a large sustainability and green building professional community. Its members overlap with IBPSA-USA's audience and it offers competing educational content, conferences, and certifications in the broader decarbonization space.
• American Institute of Architects (AIA): AIA is the largest U.S. professional association for architects and convenes building performance content within a much broader practice agenda. It competes for the same AEC member dollars and conference attention as IBPSA-USA.
• Building Owners and Managers Association (BOMA): BOMA represents commercial real estate owners and managers and provides relevant networking, education, and advocacy in the same building performance space. It serves a related but distinct stakeholder group and competes for event sponsorship from overlapping AEC sponsors.

Emerging players

• Carbon Leadership Forum: Carbon Leadership Forum is a multi-stakeholder community focused on embodied carbon in buildings, an adjacent emerging topic to operational simulation. It targets overlapping AEC professionals and competes for thought leadership within the building performance community.
• Net Zero Conference: The Net Zero Conference is a partner event where IBPSA-USA maintains an official presence. It serves an adjacent sustainability audience with growing brand recognition and could evolve into a competing or substituting destination for IBPSA-USA members.

Direct peers

• ASHRAE: ASHRAE is the dominant U.S. association for HVAC&R and building systems professionals and co-locates semi-annual meetings with IBPSA-USA. Membership and conference audiences substantially overlap with IBPSA-USA's energy modeling community, making it the closest comparable organization.
• IBPSA-World (International Building Performance Simulation Association): IBPSA-World is IBPSA-USA's parent international federation and the global organizing body for building performance simulation. As affiliates serving overlapping professional communities with shared standards goals, they are direct peers despite the parent-affiliate governance relationship.
• Association of Energy Engineers (AEE): AEE is a professional association serving energy engineers and certified practitioners, with overlapping certifications (CEM, BEP) and conference programming. Memberships and learning offerings are directly comparable to IBPSA-USA's career development value proposition.
