Experimental comparative study of the thermal performance of the façade of a building refurbished using ETICS, and quantification of improvements

Abstract

Abstract The current imperative to reduce energy consumption in the building sector calls for the implementation of energy-saving strategies. Existing building stock also needs to be adapted to meet today’s requirements. In Spain, consumption focusses on domestic heating systems, and since most energy is lost through the building’s envelope, improving these structures is a priority strategy. Renovating facades using external thermal insulation composite systems (ETICS) is currently one of the most effective strategies available. However, studies are needed to evaluate their real performance in order to quantify these improvements. In this article, we analyse the thermal performance of the facade of a dwelling situated in a building in Madrid by monitoring surface temperatures before and after renovation with ETICS. The results show the extent to which the thermal performance of the facade is improved with respect to its original status in this type of building in the climatic conditions found in Madrid.
