Resumen Las actuaciones para la rehabilitacion del parque edificatorio existente son un punto clave en la reduccion de la demanda de energia; objetivo principal de la normativa actual relativa a la eficiencia energetica. Uno de los elementos mas influyentes en la capacidad de ahorro energetico en un edificio es su envolvente. Reducir las perdidas de energia del interior de una vivienda a traves de la mejora de las caracteristicas de la fachada es una actuacion que mejora notablemente los edificios, tanto energetica como esteticamente. En el presente trabajo se analiza el comportamiento termico de la fachada de un edificio tipico de los anos 50 que ha sido rehabilitado con un sistema de aislamiento termico por el exterior (SATE). El estudio se lleva a cabo a traves de la monitorizacion de un edificio situado al sur de Madrid, concretamente en dos viviendas, una en estado original y otra ya rehabilitada. La monitorizacion se realiza en el mismo periodo de tiempo y teniendo en cuenta la similitud de las caracteristicas constructivas de las dos viviendas estudiadas. A traves de los datos obtenidos se compara la evolucion de las temperaturas superficiales en los dos casos y en sus dos orientaciones, norte y sur. Se pretende conocer las mejoras en el comportamiento termico y la influencia del sistema SATE en esta rehabilitacion. Abstract Actions for the existing buildings rehabilitation are a key point in the reduction of energy demand; main objective of the current regulations relating to energy efficiency. One of the most influential elements of energy saving capacity in buildings is its envelope. Reduce energy losses of the interior of a house through the improvement of the characteristics of the facade is a performance that significantly improves the buildings, both energy and aesthetically. In the present work the thermal behaviour of the facade of a typical building of the 50s that has been rehabilitated with an external thermal insulation system (ETICS), is analysed. The study was performed through the monitoring of a building located in the south of Madrid, specifically in two houses, one in its original state and another one already rehabilitated. The monitoring was carried out in the same period of time and taking into account the similarity of the constructive characteristics of the two houses studied. Through the data obtained, the evolution of surface temperatures is compared in both cases and in its two orientations, north and south. It is intended to know the improvements in thermal behaviour and the influence of the ETICS system in this rehabilitation.
