U-value measurement with Build Test Solutions and Energy house Labs

In this episode, host Claire Brown is joined by Richard Fitton from Energy House Labs at University of Salford and Richard Jack from Build Test Solutions to explore how we measure the real world thermal performance of buildings.Focusing on U-values, the conversation unpacks why traditional ‘calculated figures often fall short, and how in situ measurement is transforming our understanding of heat loss, energy efficiency and building quality. Drawing on cutting-edge research from Energy House Labs and practical tools developed by Build Test Solutions, the episode highlights the surprising variability in building performance, even among seemingly identical homes.The conversation explores what U-values really measure and why they matter, the gap between predicted and actual building performance and how new technologies are enabling more accurate measurement of heat loss, air tightness and thermal efficiency. It also looks at why a measure first approach could reshape retrofit strategies, alongside the growing role of data, testing and international collaboration in improving housing standards.For further information visit:www.buildtestsolutions.comwww.energyhouselabs.salford.ac.ukThis podcast is an informal discussion between interested parties associated with Retrofit Information, Support and Expertise.
