Old walls warmer than wethink
RESULTS from the first stage of SPAB’s (The Society for the Protection of Ancient Buildings) research on the energy-efficiency performance of old buildings suggest that standard Uvalue calculations used across the construction industry underestimate the performance of traditional walls. In some instances,the heat loss through vernacular materials can be up to three times lower than expected.
SPAB’s Jonathan Garlick, says: “We appear to be actually underselling the thermal performance of our old buildings by not fully understanding them. It’s all about understanding the building first – how it performs, how we use it and how we live in it. U-values are not the complete story.”
