Technical Guidance - Modelling assumptions for steel projects

Category: Guidance

With the Passivhaus standard now being routinely applied in the UK to larger and more complex buildings, we are starting to see the emergence of more steel frame elements, or entire steel frames, being designed for Passivhaus buildings. The design of a steel frame for Passivhaus brings unique challenges, which design teams may not have encountered when aiming for less ambitious fabric performance standards.

The Passivhaus Trust has released this technical briefing note to guide the modelling assumptions required for steel frame projects, which is considered of immediate concern for teams involved in developing UK steel frame projects.

The Trust is now working on a more detailed technical position paper on steel in Passivhaus construction for publication later in 2022.
