Professor Richard Fitton from Energy House Labs will be speaking at an upcoming free webinar on Thursday 05 February 2026, focused on the use of measured U-values to improve building performance, compliance, and retrofit outcomes.
Titled Better Data, Better Buildings: Using Measured U-Values to Drive Performance and Compliance, the webinar will explore growing evidence that commonly assumed U-values used in EPCs and energy models can be inaccurate by as much as 40 to 100 percent. These inaccuracies can result in EPC ratings shifting by whole bands, affecting investment decisions and the effectiveness of retrofit programmes.
Professor Fitton will be joined by Richard Jack from Build Test Solutions and Andrew Parkin from Elmhurst Energy. Together, they will present findings from field trials and real project case studies, demonstrating how in situ measurement of building fabric can improve accuracy and support better decision making.
The session will also show how measured U-values can be integrated into existing modelling software, allowing improved outcomes without requiring changes to current systems.
The webinar will be relevant to housing providers, retrofit professionals, energy assessors, and policymakers involved in building performance, EPCs, and net zero delivery.
