Join us for a deep-dive Passivhaus Retrofit Masterclass exploring an Passivhaus retrofit by components project currently under construction. With few UK examples of this pathway, the session offers a rare opportunity to examine the method in practice - from design intent through to on-site delivery and certification.
In this advanced level session, we’ll look closely at the project’s technical development, including floor upgrades, envelope strategy, THERM calculations, PHPP progress and the practical challenges of implementing the component method on a first project. The Passivhaus Certifier will also share insights drawn from wider retrofit experience, placing the project within the broader context of Passivhaus retrofit practice.
