Solar radiation for buildings and energy applications: the feasibility of the reduced data set for Mediterranean sites

2007

In the last years several computer programs for thermal simulation of buildings have been quickly spread; they allow to describe the thermal behavior of buildings and to verify their energy efficiency, in order to suggest eventual improvements as from the design stage. Most of these simulation tools generally need a complete input data set and, in particular, information referring to the climatic conditions of the site where buildings will be built-up. As it is well known, among climatic issues, particularly important for the thermal energy balance is the solar radiation. In this paper authors present a short reference year of the solar radiation, more precisely the Monthly Average Day (MAD…

Natural Radioactivity in Clay and Building Materials Used in Latvia

2015

Abstract This paper presents the results of natural radionuclide concentration and activity index study in materials used for construction in Latvia. Special attention is given to clay and clay ceramics. Concentrations of K-40 and Th- 232, U-238 radioactivity were determined using gamma-spectrometry method. In some building ware, maximal concentration of K-40 was 1440 Bq/kg, and of U-238 - 175 Bq/kg. In granite, the determined maximum concentration of Th-232 was 210 Bq/kg. It was found that radionuclide content in different period clay deposits can differ by more than two times, and up to five times in different clay ceramics. The results obtained are compared with analogous data from the o…

Some Features of Modeling Ultrasound Propagation in Non-Destructive Control of Metal Structures Based on the Magnetostrictive Effect

2023

A method and mathematical models of direct and inverse problems of ultrasonic testing and diagnostics of complex metal structures for defects were developed and tested. A prototype of a system for magnetostrictive control of elements of the objects under study was manufactured and experimentally tested. Mathematical simulation of ultrasonic testing processes using MATLAB and the COMSOL Multiphysics software environment was carried out. The adequacy of the mathematical models was verified by the results of their comparison with real physical experiments. Information support and a methodology that implements it was developed, which ensure the functioning of the control facilities for these ob…

A reckoning with the maintenance of the built environment, a Sisyphean task

2023

Maintenance concerns most of the artifacts, referring simultaneously to the socio-cultural, technical and managerial spheres. Contemporary scenarios impose an overall rethinking, where key-topics such as tradition, consumerism, sustainability and digitization become pivotal in the search for suitable production models, between post-industrial and neo-craftsmanship, in order to have fresher references for the maintenance activities.
 In the construction field, maintenance is not limited to the objective of prolonging the duration of quality levels that only affect direct users, but also has important implications of a social and collective nature, in the case of both public and private …

THE BUILDING RECOVERY OF A TRUTH OF PALERMO (SICILY)

2008

The building recovery of a truth of Palermo (Sicily) -The study means to make its contribution to the knowledge and to the recovery of the architectural patrimony which is chronological inserted in the arc of xxth century, to study its cultural and material weaving, spotlighting the truth of Palermo. It is characterised by an evident heritage and hidden inheritances which seem to be from successive human vicissitudes, This research aims at the creation of new models of interpretation of the cultural heritage,

HISTORICAL SCIENTIFIC AND EXPERIMENTAL RESEARCHES AIMED AT FINDING NEW TECHNIQUES AND INSTRUMENTS TO RECOVER

2005

The “building recovery” has been the key point of various talks that, since the ‘60s, have regarded planning and urban landscaping. The reinforced concrete-ruled XXth century has generated buildings that have resulted technologically flawed, if not altogether unattractive. These flaws can be justified by premature use of certain techniques (not will-known the necessity of historical research), but this can not justify the modern degraded townships, the loss of local urban characteristics and the environmental unbalancing. Where sites are of XXth century cultural heritage? Which are the methodologies for documenting and managing? This research is aimed at analysing new techniques and materia…

Restoration and enhancement of KOS City - Greece

2012

Abusiveness phenomenon is an essentially political, social and economi-cal fact in all territories that determines a disadvantage in the community and in its environment. Architectural is “the science of living” and it is called to answer on a problem which is progressively go destroying living places. Architectural must therefore answers to housing needs. Abusiveness is a housing emergency which oppresses towns and citiziens. Architectural does-n’t feel guilty because for too many years architects did something else, cor-rupted building did the rest.

BUILDING REHABILITATION AND SUSTAINABLE URBAN REGENERATION: CIANCIANA A CASE STUDY IN SICILY

2016

The paper investigates issues related to the principles of eco-sustainability and criteria of design choice to be made in respect to the characteristics of the interventions. It proposes cases of recovery and re-use sustainable in Sicily, whose choices of action were made in respect of the environment and local traditions. General directives: reduction of the energy consumption; use of recycled and recyclable materials; improvement of the thermo/igrometric. The programming is based not only on the control of the performance, but on an idea of global quality of the operations. The correspondence between the needs and the requirements of the organism and the norms that protect the user, it's …

Trasparenze mediatiche

2009

Tra tutti, l'involucro edilizio è quello che più di ogni altro componente del manufatto architettonico ha permesso di veicolare informazioni a scala urbana. La sua forza espressiva e simbolica si è manifestata nel passato quando lna sua struttura portante, realizzata con spesse mura perimetrali, fungeva da barriera difensiva e visiva; o quando, abbellita con stucchi e decori esprimeva la ricchezza e i fasti di un mondo fatuo; o, ancora, con le sue grandi vetrate colorate filtrava la luce e trasmetteva al mondo il suo messaggio spirituale. La stessa forza espressiva e simbolica si manifesta oggi con le nuove tecnologie applicate all'involucro edilizio, inteso come luogo di controllo delle pe…
