Brian has long been passionate about Passivhaus and Enerphit design and in 2022 his practice Printie James Architecture collaborated on an Enerphit project in Findhorn for a London-based architect. Working alongside a Certified Passive House Designer through the Building Warrant stage proved to be a pivotal experience. Driven by this, Brian undertook Passivhaus training with MosArt Ltd in early 2025.
