“…To a large extent, the enhancement of the EE of buildings has been achieved by improving the thermal performance of the opaque envelope through the widespread use of thermal insulation systems [22], [23]. Yet, in contemporary residential buildings, more than 50% of the energy consumption is used for space heating and air conditioning in EU members [28][29][30], and the main mechanism through which energy is lost to the environment is associated with the renovation of indoor air.…”

Highlights Summary of recent developments and work at ADAI's Energy, Environment and Comfort research group is presented  The Indoor Live Lab (I2L) and an e-learning course on Indoor Environmental Comfort in Buildings are introduced  The paper aims to present the facilities, instruments and the purposes behind I2L project  Several Indoor Environmental Quality (IEQ) parameters studies are discussed in particular 1 AbstractIn this paper some of the recent developments and ongoing work at the Energy, Environment and Comfort research group of ADAI (Association for the Development of Industrial Aerodynamics), in the areas of Indoor Environmental Quality and Energy Efficiency in Buildings are presented. Summarily, it is showcased a state of the art of the Indoor Live Lab, developed at the Mechanical Engineering Department of the University of Coimbra. The Indoor Live Lab (I2L) is a new platform for research and technology demonstration in IndoorEnvironmental Quality (IEQ). The main motivation for initiating this effort arose from the increasing necessity that researchers, educators and decision makers have for continuously available monitored data on all aspects of building functioning. This paper aims at presenting early developments at the I2L, as well as associated research projects which were at the centre of its creation. Firstly, the objectives of the I2L are presented. Secondly, ongoing research on both residential buildings and services buildings is exposed. After, the several IEQ parameters studies are discussed in particular. This is followed by the I2L description, location and specific features. Finally, a conclusion and future work section is presented.

“…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.

“…puncturing). In some studies the application of VIPs in new constructions or existing buildings was investigated (IEA/ECBCS, 2001; Johansson et al, 2014b;Mandilaras et al, 2014;Mukhopadhyaya et al, 2014). Others explored possible developments of VIP technology concern new ways for fixing the panels to the other envelope layers (Boafo et al, 2014(Boafo et al, , 2015 or the alternative use as internal thermal breakers (Sallée et al, 2014) or innovative sandwich panels (Voellinger et al, 2014).…”

In this paper a numerical analysis aimed at evaluating the thermal performance of vacuum insulation panels (VIPs) at the building scale is presented. This technology has seen considerable development over the past few years, gaining increasing penetration in the building insulation market. However, it is important to evaluate correctly the thermal bridging effect that occurs when the VIPs are coupled with joints at the building scale. To this purpose, the linear thermal transmittances of different VIP assemblies inserted in several wall configurations were assessed through a bidimensional numerical analysis. Moreover, to evaluate the influence of thermal bridges on the building energy need, quasi-steady-state simulations for a parametric building module were performed. A simple empirical model was finally built to estimate the linear thermal transmittance from basic input variables. The study demonstrates that thermal bridging effects that occur when VIPs are jointed are never negligible and they could have an important impact on the building heating energy need.
