Bozeman BS + Beer

BS* (Building Science) + Beer is a discussion group for builders, architects, engineers, tradespeople, and anyone interested in better building in the Gallatin Valley area.

Building science applies the principles of physics, thermodynamics, and fluid dynamics to understand how buildings perform. Each month, we gather at a local brewery, pub, or job site to explore industry topics, share practical knowledge, enjoy a few refreshments, and strengthen Bozeman’s high-performance building community.

Presentation: Passive House Prefab for Busy Builders

Brothers Mark Tumason of Eesome Builders and Paul Tumason of Tumason Builds bring experience from nearly 50 Passive House installations, four ground-up Passive House projects in Bozeman, numerous high-performance retrofits, and multiple European-style window and door installations.

They’ll host Mariana Pickering and JD Scott of B.Public Prefab in Santa Fe, New Mexico, for a presentation titled “Passive House Prefab for Busy Builders.” The discussion will explore off-site solutions for purchasing, delivering, and installing complete thermal and structural building envelopes.

B.PUBLIC Prefab is a woman-owned public benefit corporation built around the belief that high-performance, sustainable housing should be within reach for more people. We design and manufacture off-site wall, floor, and roof panel systems for single-family and low-rise multi-family construction. Our precision-built approach means healthier indoor spaces, carbon-storing materials, above-code energy performance, and faster enclosure on site. The result is a simpler, more predictable process for builders, architects, and developers.

New Location: Bozeman Cohousing

The venue for this event has changed to Bozeman Cohousing, 3120 Wagonwheel Dr., Bozeman. Please note that on-site parking is limited, so please carpool, walk, or bike. If you need to drive solo, please park on Fieldstone or Concord adjacent to the venue.

Bozeman Cohousing is Montana's first cohousing community and is a market-rate Net Zero Energy neighborhood of 43 dwellings. The design employed Passive House strategies and standards to achieve these benchmarks in a production construction context. The neighborhood was recognized by the American Institute of Architects as the nation's premier community-based housing project of 2025 and is the first multi-family housing project in Montana to receive the AIA's national housing award.

Thank you to Studio Cohab for helping host this event!
