Old walls warmer than we­think

Yorkshire Post - Property - - PROPERTY -

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.”
