Assessment of thermal performance and surface moisture risk for a rear-ventilated cladding system for façade renovation

Ventilated façade systems, incorporating thermal insulation behind a rear-ventilated cladding, constitute a popular renovation solution in warm European climates. For compliance with building regulations, their energy efficiency is usually obtained through simple onedimensional desktop calculations, which do not consider the impact of the support elements of the cladding penetrating the thermal insulation. This study assesses a ventilated façade system anchored over a solid concrete wall with adjustable stainless steel brackets. One-dimensional calculations are compared against three-dimensional numerical thermal modelling, evaluating the effect of insulation thickness (40–100 mm) and potential gaps in the insulation around anchors. Results indicate low risk of condensation and mould growth over internal surfaces. The additional heat flow induced by stainless steel anchors, which is not considered by simplified calculations, appears lower than for aluminium-based systems but can become significant as insulation levels increase. Ensuring the continuity of insulation around anchors is critical for keeping this additional heat flow at reasonable levels (8–13%). If gaps in the insulation are present around anchors, the additional heat flow increases substantially (25–70%) and pushes effective U-values above 0.4 W/m²K, thus resulting in unforeseen energy consumption and noncompliance with regulatory requirements in many European locations.This study has been partly developed within the InnoWEE research project.

La intrincada fenomenología del metatexto cinematográfico

El llamado séptimo arte produce ingentes derivaciones metatextuales, textos que se refieren al cine y/o a las películas de muy diversas maneras. Las páginas que siguen pretenden poner cierto orden en ese abigarrado archipiélago discursivo en el que conviven la crítica de películas, la teoría cinematográfica, la historiografía del cine y el análisis fílmico. Y lo hacen poniendo el énfasis en las diferencias que median entre la crítica y el análisis, discursos de tono, perspectiva, metodología, amplitud de miras y factura manifiestamente divergentes que pese a toda evidencia constituyen una misma cosa para el despistado cinéfilo de a pie.From its very beginnings, cinema has produced an impressive body of literature covering every possible aspect of the art of film The following pages try to put some order to this complex archipelago of criticism, theory, historiography and analysis of film. This is done by emphasizing the differences that separate criticism and analysis and such divergent aspects as essays on tone, point of view, methodology, scope and origin of film (although the average film goer does not usually make these distinctions)
