Passivhaus Retrofit: How far can every building go?
The UK cannot meet its climate ambitions by focusing on new buildings alone. The greatest opportunity lies in improving the buildings we already have. Successful retrofit is rarely about chasing a single target. It is informed decision-making that achieves the best possible performance while avoiding costly mistakes and keeping future improvements open. Passivhaus retrofit provides a robust approach to delivering low-energy, comfortable and resilient buildings. Drawing on the Passivhaus Trust's latest research and real-world case studies, this session explores how Passivhaus retrofit can be applied across housing, and non-domestic projects. From whole-building EnerPHit retrofits to carefully planned staged upgrades, our panel will examine what good retrofit looks like, how performance can be verified, and how clients can balance ambition with practical delivery.
