“…The layer must be a reasonable thickness -minimum 40 mm, recommended 50 mm -except for masonry walls with air layer, where the air layer thickness may be up to 12 cm; have holes/slots connecting to the outside atmosphere located at the bottom and top of the façade, except in cases where the layer(s) located between the ventilated air layer and the outside of the façade have open joints or perforations; and if the vertical continuity of the ventilated air layer and the exterior [18][19][20][21][22].…”

Reducing the energy consumption needed for creating suitable indoor conditions has become a significant issue on a global scale. The building’s envelope and service systems have the most important influence over the amount of energy consumed. This aspect is related to reducing the heat flux across the building envelope in summer conditions and preventing the condensation and infiltration risk in the winter period. The research regarding ventilated façades has advanced taking into account these advantages, which emphasized the need to study and create constructive solutions adapted to the conditions. In this context, this paper represents a brief introduction to ventilated façades solutions, taking into account the definition, their characteristics, the principal constructive elements, the main types of ventilated facades, and last, but not least, their advantages and disadvantages. The authors believe that the study is critical in fully comprehending the characteristics of these systems and their primary components, as well as designing and implementing them in accordance with current environmental needs. It is anticipated that comprehending this concept, as well as its evolution and trends, can contribute in the resolving of a number of ecological and societal issues.

La calidad del ambiente térmico es determinante en la sensación térmica percibida del usuario, por lo que los efectos de los sistemas constructivos utilizados en la edificación son clave en la habitabilidad térmica del espacio. El conocer el desempeño térmico con la técnica de monitoreo permite una evaluación realista bajo las condiciones del microclima donde se construye. El objetivo de este estudio fue evaluar el ambiente térmico del periodo de transición y frío de dos viviendas construidas con un sistema constructivo de ensamblado (Thermorock), aplicado en muros y techo, para establecer las variaciones de temperatura de bulbo seco en su interior comparándolas con un caso base de un sistema de uso predominante en un clima cálido seco extremoso (Mexicali, Baja California). Se desarrolló una estrategia de monitoreo con siete puntos de medición en una vivienda; dos puntos en otra y dos más en una vivienda de referencia, más un sensor al exterior en cada una de las viviendas. Se colocaron los sensores con base en la normatividad de ISO 7726 y ASTM 168 – 97. Los resultados indican que el sistema evaluado permite condiciones de confort térmico para los usuarios en un clima desértico.

“…A relevant topic which has been of the highest interest of the building physics research community is the investigation of the performance of thermal bridges [43][44][45]. A thermal bridge is an area or a component of an object which has lower thermal resistivity than the surrounding materials, producing a pathway of a higher rate of heat transfer [46].…”

Inevitably, the 21st century has initiated a series of developments in the construction industry, leading to its digitalization and resulting in a series of innovative approaches and practices. At the same time, the construction industry, being one of the main global environment polluters, should fulfil well-established, as well as novel, sustainability requirements in order to evolve in harmony with the rising concerns on the availability of natural resources. This overview study aims to present the main developments, research, and scientific challenges in the field of sustainable construction, emphasizing the field of energy. The study aims to present a state-of-the-art scientific discussion on the sustainable built environment topic by analyzing cutting edge topics in the fields of building elements and whole building energy assessment, of indoor air quality and low carbon buildings, as well as on sustainable energy systems and smart buildings. The study also presents the state-of-the-art in existing tools which are adopted for the assessment of the sustainable built environment, including the use of digital tools and building information modelling for the energy assessment of the built environment, as well as the application of Life Cycle Assessment on building-related processes. Cross cutting issues related to the analysis of the building sector in the Industry 4.0 era, such as sustainability management topics and environmental geomatics are also discussed. The study concludes in those fields which will be of interest of the scientific community in the following years, towards achieving the goals of the sustainable development of the building sector.
