This research presents a new intervention methodology on arches and vaults of a Renaissance factory in the Colegio Santo Domingo de Orihuela (16th century) using 3D software LIDAR technology that verifies the execution process of the works studying the different charges states and structure behavior. This document aims to explain a working methodology in the monitoring of structural repair interventions in the architectural heritage, in the specific case of the replacement of traditional one-way timber joist frame slabs on structures of former, splay and groin arches between vaults. This involves the compilation and processing of two types of data: on the one hand, the analysis of the different load states to which the intervention is exposed in its different phases: initial, dismantling of the different layers of traditional construction and replacement by the new structural system; and, on the other hand, the graphic information provided by the photogrammetry techniques used to dimension and define the spatial position of the structural elements that have historically resolved the covering of the architectural space in this type of Renaissance solution. The different layers and demolished materials have been verified by analysing their constructive disposition, thicknesses, and dimensions of the elements that formed part of the initial construction system and their own weights. In addition, the new construction systems used in the restoration project generate a state of loads similar to the existing one. The LIDAR technology used in the research process provides graphic data of the spatial position of the arches and vaults studied in the different states of the construction intervention. The point clouds obtained are analysed by taking as reference fixed points (considered unalterable and infinitely rigid) of the refectory and the coordinates of the initial and final states are compared. The results show minimal variations between the two positions, which justifies the goodness of the construction methods used and the structural safety obtained in the complex. This methodology applied to arches and vaults in heritage architecture guarantees the control and recording of the movements produced in the process.
Energy renovation of buildings in the European Union would lead to considerable energy savings and a 26% reduction in energy consumption. Despite this and the programmes implemented to promote it in the residential environment in Europe and the United States, the barriers that homes, contractors, and finance companies face to undertake these processes have slowed down the results. The emergence of one-stop-shops (OSSs), promoted by European directives, as integrated management entities to promote the energy renovation of dwellings seems to be a central element in the development of future strategies. This paper looks at experiences of implementing OSSs in Europe, tries to identify the main factors of success, and proposes lines of action to strengthen OSS operation in the long term. To achieve this, documents, regulations, and data on the context were studied, and active cases of OSSs were analysed. Experiences of OSSs that are no longer operating were identified to determine why they had closed down. The results suggested that a lack of structural funding is one reason why activities terminated and that the most successful cases applied an ‘all inclusive’ model and supported families in the entire process.
A pesar de las incontestables ventajas de la rehabilitación energética la tasa de renovación residencial es preocupantemente baja, en tanto las barreras para los hogares son infranqueables. Posiblemente se ha sobrevalorado la capacidad de éstos para emprender un proceso muy complejo que requiere conocimientos técnicos, financieros y de gestión. Así, recientemente han aparecido en la escena internacional One-Stop-Shops (OSS) para asistir de forma integral a la rehabilitación residencial. Este artículo estudia, mediante un análisis documental y entrevistas en profundidad, el panorama de las cuatro experiencias pioneras españolas. Los resultados destacan el importante papel que juegan las administraciones y los proyectos europeos como fuente de financiación y, sobre todo, de conocimiento específico; así como los obstáculos que se han superado para implementarlas y los de resolución pendiente. Estas iniciativas se vislumbran como instrumentos indispensables delante del arribo de los fondos Next Generation European Union (EU).
