THE UNIVERSITAT AUTÒNOMA DE BARCELONA’S DEPARTMENT OF CHEMISTRY BUILDINGS PROVIDE THE PERFECT SETTING FOR A THERMOGRAPHIC STUDY ON THERMAL COMFORT AND ENERGY EFFICIENCY PERFORMANCE COMPARING A VENTILATED FAÇADE WITH ONE MADE OF CONCRETE. Hosted within the Department of Science complex, the Department of Chemistry occupies two interconnecting buildings in the Universitat Autònoma de Barcelona’s Bellaterra campus. Built in the late 1960’s, these two box-like buildings are among the oldest structures on the university grounds. While one has a painted concrete exterior, the other was renovated and displays a ventilated façade. One of the buildings underwent a major refurbishment in 1992, as it needed to accommodate new laboratories and a high concentration of equipment. Because Spain already had in place its rst norms on the thermal regulation of buildings, it was decided that a ventilated façade was the best solution to refurbish the building made of precast concrete. Trespa® Meteon® panels in Mid Grey were chosen as cladding. More than 20 years later, the Department’s facilities is providing the perfect setting for a thermographic study on thermal comfort, condensation and energy e ciency performance with and without a ventilated façade. “We have the phrase ‘an image is worth a thousand words,’ well this setting allows us to include in just one thermographic image the behaviour of a traditional façade next to one clad with Trespa® Meteon®,” says Xavier Viola i González, director of Efcore, the Spanish rm in charge of the study.
