Los cambios normativos derivados de la aprobación de la Ley 8/2013 de Rehabilitación, Regeneración y Renovación Urbana van a suponer un antes y un después en los habituales modos de plantear los procesos de reforma de los bloques de vivienda colectiva. El artículo analiza las consecuencias de dichos cambios en el ámbito de la obligada rehabilitación energética de edificios y su repercusión económica y social. El análisis se fundamenta en el estudio comparado de treinta y dos edificios rehabilitados en los últimos años, confrontándolos con el hipotético coste económico que la aplicación de dichos cambios hubiera supuesto en sus respectivos procesos de ejecución. Los resultados obtenidos evidencian que para alcanzar los objetivos previstos, resulta fundamental potenciar la oferta de ayudas públicas, sugeridas en la ley pero no reflejadas en la práctica, en aras de la sostenibilidad del proceso y para que las mejores intenciones no deriven en un problema social. Se justifica analíticamente la teoría escogiendo un ejemplo de la obra de Félix Candela, ejecutada por medio de cáscaras cilíndricas largas de cubierta, y elaborando el proceso de cálculo necesario propuesto.

In this article, it is presented the experience of the Educational Innovation Project accepted by the Basque Country University, which is being developed since 2014 at the Polytechnic University School in Donostia. This project highlights for being the first teaching experience in the Technical Architecture Degree, where teams of teachers from different subjects are developing a work in a cooperative, joint, coordinated and collaborative way, and encompassing the full spectrum of the design - construction process closely with the architecture professional dynamics. BIM technology (Building Information Modeling) is being used so that the same three-dimensional parametric modeling is shared among different subjects, for the resolution of real Learning Based Projects, linking teaching and labor market. En esta comunicación, se presenta la experiencia del Proyecto de Innovación Educativa aceptado por la Universidad del País Vasco, que se está desarrollando desde 2014 en la Escuela Universitaria Politécnica de Donostia. Destaca por ser la primera experiencia docente en el Grado en Arquitectura Técnica, donde equipos docentes de diversas materias están desarrollando un trabajo de manera cooperativa, conjunta, coordinada y colaborativa, abarcando el espectro completo del proceso proyectual-constructivo en estrecha relación con la dinámica profesional Arquitectónica. Se está empleando la tecnología BIM, (Building Information Modeling) de manera que se comparte un mismo modelado tridimensional paramétrico entre diferentes asignaturas, para la resolución del Aprendizaje Basado en Proyectos reales, enlazando docencia y mercado laboral.

The evolution of the quality of an artificial material in subsequent periods should not present setbacks. Technological development and monitoring the execution should ensure a favourable outcome in quality. However, socioeconomic and political forces can distort the course of this evolution, making it impossible for a linear reading; serving as an example of this is the history of reinforced concrete in Spain. The material was introduced to Spain about 120 years ago from European patents. After the war, and after several glorious decades, came the decline of these patents with the consequent liberalization of the technology and the publication in 1939 of Instruction for Concrete. This liberalization came into effect in a context of scarcity and high cost of construction materials, so that the concrete used in the reconstruction of the cities turned out to be a very poor material. Various decrees and orders published at this time established a number of limitations in the use of iron and cement, both depleting the quality of the material used, and as a result, developing a black market, further adding to the decline in quality. Later in the 60s, overcoming these constraints, the quality of materials began to improve. In 1973, a new regulation on the use of concrete introduced a section on quality control. Thereafter, the increasing control ensured the proven quality of the material and its continuous improvement to the present day. A series of tests conducted in buildings made of reinforced concrete in the Basque Country during the twentieth century, shows that the strength and quality of concrete from 100 years ago can be much better than of concrete from 60 years ago, attesting to the inability to perform a linear reading of its evolution.

- Abstract
The conservation of constructions, and especially of built heritage, requires complex studies concerning their Global Vulnerability. These studies have to consider the current state of the building, i.e. the degradation degree, and the factors that mostly affect the building and, therefore, generate alterations. These factors are not limited to the structure of the building, location and environmental factors are also involved. Hence, the assessment of built heritage vulnerability should consider the building itself and also be extended to the site and the environment. This work presents a systematic and reproducible methodology for the quantification of the Global Vulnerability in different typologies of constructions and environments. The proposed methodology establishes a relationship between the existing alterations (A) and the main factors (F) that affect vulnerability (V) by means of an AFV (Alteration/Factor/Vulnerability) diagram. Based on these results alteration and vulnerability indices are calculated. The obtained AFV diagram allows the comparison between different constructions or separate areas within the same construction. This methodology was validated in two early twentieth-century constructions that form part of the reinforced concrete architectural heritage of the Basque Country: the Punta Begoña Galleries (Getxo, Spain) and the Aqueduct of the Araxes paper mill (Tolosa, Spain)., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.
