Principal, Building Performance Architecture

Robert J. Hosken, AIA, BECxP, CEM

Architect - Building Envelope Specialist

For more than 30 years, Robert "Rob" Hosken has combined architecture, building science, and energy performance to help create buildings that are healthier, more durable, and dramatically more efficient. As Founder and Principal of Building Performance Architecture, Rob works with owners, developers, architects, and contractors to integrate advanced building enclosure science with thoughtful architectural design, ensuring projects perform as intended long after construction is complete.

Rob's passion for high-performance buildings began early, growing up in a passive solar home in Wisconsin that required virtually no heating on sunny winter days. That experience sparked a lifelong fascination with how buildings interact with energy, climate, and the people who occupy them. His interdisciplinary background in architecture, physics, acoustics, music, writing, and art continues to shape his holistic approach to building performance today.
