Upside-down ship’s kel-shaped vaults as a contemporary design criteria. The case of the Palace of the Dukes of Braganza in Guimarães (Portugal)
2015
A contemporary worldwide trend is exposing the structural elements of a building to create an articulate and complex architecture whose lines of force give robustness, stability and, at the same time, a sort of lightness and frivolity to the entire construction. However, the combination between the visual conception of architecture and the principles of statics is not new to the world of construction. Exposed structure as a design approach may be observed in many historical buildings, either public, religious or private, and in several cultural and geographical areas where exposed structures communicate power, solidity, and rigour along with an instance of economy and lightness. In this wor…
Wooden domes, vaulted and flat ceilings, partition walls in the Sicilian constructive tradition knowledge for the safeguard of architecture abd techn…
2014
The domes, vaulted and flat ceilings and also the partition walls built with wood and reeds had a particular diffusion from the XVII century, in Palermo as well as in other countries of Sicily, in many regions of Italy and in the whole Europe. The consolidated constructive tradition made them one of the most appreciated and usual systems for structural frame and for the definition of interior rooms, employed both for the monumental housebuilding and for that of minor importance, also owing to the adoption of economic materials. These wooden structures in the monumental architecture contain the rich pictorial and stucco decoration and define - together with other aspects of quality - the aul…
Modelli lignei e architettura in Sicilia tra XV e XVI secolo
2020
La realizzazione di modelli lignei nel processo di creazione di opere architettoniche in Sicilia è documentata a partire dalla fine del XV secolo. Oltre ad alcune testimonianze nel campo dell’architettura militare, si tratta principalmente di edifici chiesastici, nei quali una articolata committenza svolge un ruolo propositivo. Nell’ambito delle comunità benedettine, in particolare, trova riscontro l’esistenza di un modus operandi che include la realizzazione di modelli lignei. Da tale modalità operativa, tuttavia, non rimane esclusa l’architettura civile. Questo contributo analizza le testimonianze relative a tale casistica, valutando l’attendibilità per il contesto in esame dei parametri …
Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light
2017
Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…
Less is future: landscape as the key element for the “milieux” renaissance in the former East Germany
2013
Twenty-two years ago, Germany was reunified as a single state. Waste land, pollution and empty buildings are some of the problems that the people had to face, along with radical and painful political reorganization. The strong collective reaction to these environmental and social disasters was heart-warming. Hundreds of coordinated and collective actions of renovation in open spaces were carried out. People were involved in each level of the design process in order to decide the best way to improve and promote the heritage and identity of their landscape. Halle, Dessau, Leipzig, and Berlin are some examples explained in this paper which demonstrate that these successful massive actions are …
