“…The results obtained for the façades orientation (North, South, East and West) are plausible and consistent with reality; façades facing North and West feature the lowest expected service life when the graphical method is used, while the façades facing South have slower decay trends, showing the best behaviour. These results are reliable because façades facing North are cooler and more susceptible to moisture and biological growth (Kuenzel & Sedlbauer, 2001;Barreira, de Freitas, & Delgado, 2013), and façades facing West are more exposed to solar radiation, facing in some cases, more abrupt temperature gradients (Barreira & Freitas, 2013;Gómez-Heras, Smith, & Fort, 2008), which compromises the performance of ETICS over time. Therefore, the North/NE and South/SW orientations were quantified with a k value equal to 0.8 (unfavourable) and 1.2 (favourable), respectively.…”

“…According to Barreira and Freitas (2013), during the energy crisis of the late 60s and early 70s, the interest in exterior thermal insulation gradually increased. Thus, ET-ICS became a popular solution among the construction companies, due to the emerging awareness regarding the reduction of the energy consumption.…”

Abstract. This study intends to develop a methodology for service life prediction of ETICS (External Thermal Insulation Composite System), based on the factor method. The methodology adopted is based on data collected during visual inspections of buildings under current conditions of occupation and exposure, contemplating the degradation mechanisms and the characteristics of ETICS. This research can also provide a suitable tool to aid the planning, implementation and rational use of building management systems in several ways, namely: i) improvement of the materials' performance, based on the optimization of maintenance actions, use of resources and maintenance costs; ii) selection of the best constructive solution, based on the knowledge of the evolution of degradation of ETICS, according to their characteristics; iii) analysis of the economic and environmental impacts of buildings during their life cycle, based on the knowledge of the number of replacements required during this period of time.

“…They comply with all requirements in terms of thermal protection, energy saving and environmental protection. c) Façade + ETICS (External Thermal Insulation Composite System): this refers to a façade with a thermal insulation system on the outside (38,39). It consisted of clay bricks, inside cladding made of rendered plaster around 0.015 m thick, with a thermal conductivity of 0.57 W/m·K, in line with the relevant standard (23), and an ETICS outer sheet of insulating material attached to the wall mechanically, by adhesive or by a combination of the two.…”

This paper compares the equivalent thermal transmittances of different façades built using commercial clay bricks with three different thicknesses and façades made using the same method but with ceramic bricks with optimized rhomboidal interior geometry.Equivalent thermal transmittances of 0.300 W/m 2 ·K were recorded for the rhomboidal brick with a thickness of 0.290 m and a façade with thermo-acoustic insulation and a large format brick on the interior, but the final thickness of the façade was 0.445 m. RESUMEN: Influencia del tipo de bloque de arcilla aligerada en la transmitancia térmica equivalente de diferentes tipos de fachadas en edificios.En el presente trabajo se comparan las transmitancias térmicas equivalentes de diferentes fachadas ejecutadas con bloques comerciales de tres espesores 0,290 m, 0,240 m y 0,190 m, con el mismo montaje pero con un bloque cerámico optimizado con geometría interior romboidal.Se ha obtenido una transmitancia térmica equivalente de 0,300 W/m 2 ·K para el ladrillo con geometría romboidal de 0,290 m de espesor y pared con aislamiento termoacústico y gran formato en el interior, con un espesor total de fachada de 0,445 m.Para fachadas ventiladas con el ladrillo romboidal propuesto con espesores de 0,290 y 0,240 m, se obtiene una mejora de un 8%-9%, con valores de 0,312 W/m 2 ·K y 0,339 W/m 2 ·K, respectivamente. Podemos concluir que, dada la pequeña diferencia en términos térmicos, la mejor opción es el uso de ladrillos de 0,240 m de espesor, siempre y cuando el espesor total de fachada no exceda los 0,300 m.

Abstract-Meteorological stations are now-a-days used worldwide in many different fields: agriculture, civil engineering, thermal comfort, architecture, renewable energy, etc.The Laboratory of the Building Physics (FEUP) in collaboration with mechanical department, has been, supporting on-line delivery of the data from a meteorological station. This system has been used since nineties with great success in teaching and researching activities support both, in Civil and Mechanical Departments and also shared internationally for wide use.The numerous activities performed based on this on-line experiment motivated the authors to share some case studies currently used in Engineering curricula.
