Building Energy Performance: A LCA Case Study of kenaf-fibres insulation board
2008
Abstract The paper presents a life cycle assessment of a kenaf-fibre insulation board following the international standards of the ISO 14040 series. Each life-cycle step has been checked, from kenaf production and board manufacture by an Italian firm, to use and disposal. The aim is to assess the board eco-profile and to compare, on the basis of a life-cycle approach, the energy and environmental benefits and drawbacks related to its employment into a typical residential dwelling. A comparison among various insulating materials has been carried out. The study focuses also on processes and input materials which cause the main environmental impacts of the product, and points out critical issu…
DIFFERENT APPROACHES TO DATE BRICKS FROM HISTORICAL BUILDINGS
2014
Abstract The application of Thermally (TL) and Optically (OSL) Stimulated Luminescence on bricks used as building material has allowed solving an chronological issue in the field of historical building dating. The possibility to use one or more methodologies of dating is closely related to the luminescent and granulometric characteristics of the sample. Using some brick samples collected in the church of Sain Seurin in Bordeaux (France), this paper discusses the implications and the possibility to use different approaches and techniques for dating. With this aim luminescence measurements were performed on both polymineral fine grain and quartz inclusion phases extracted from each brick. For…
Active-passive control strategy for adjacent buildings
2011
Author's version of a chapter in the book: 2011 Proceedings of the American Control Conference. Also available from the publisher at: http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=05991059 In this paper, a control strategy to mitigate the vibrational response of adjacent buildings under seismic excitation is presented. The proposed strategy combines inter-building passive actuators with active actuators placed in the building stories. The main ideas are presented by means of a simplified two-building model; however, a semi-decentralized overlapping approach via the inclusion principle has been used to impose a proper information exchange structure suitable for wireless control of larg…
Terres et pierres pour matières de cultures : l'apparition et la diffusion de nouveaux modes et matériaux de construction dans le Nord-Est de la Gaul…
2017
Roman building materials often arose a growing interest through their presence in early contexts, sometimes way before Gallic Wars. Made from natural resources, their final shape corresponds to anthropogenic and cultural constraints. However, even if building materials are not neglected during archaeological excavations, so far they have been considered as playing a minor part in understanding ancient sites. Economical, technical and architectural aspects are regularly mentioned, creating the picture of an exploited « landscape » around the studied areas, but the question of materials as cultural markers witnessing intercultural relations between Rome and Gallic tribes has never really been…
Pierres et carrières : réflexions autour de différentes stratégies d’approvisionnement sur les chantiers bourguignons médiévaux
2021
In this paper, we want to discuss the complexity of the mechanisms of medieval building stone supplying based on a diachronically and multidisciplinary inquiry on several Cistercian and ducal study cases. The first results enlighten the constraint caused by land property that limits the builders to a supplying network shaped by domain and law. Thanks to the growing vitality of trade and the arrival of independent stone providers, criteria of selection gradually focus on stone itself. Both global and individual strategies evolve then, reinventing the networks of stone providing and the markets.
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…
Environmental performance of building materials: life cycle assessment of a typical Sicilian marble
2009
Background, aim, and scope: The building sector is strategically important for achieving sustainability. Therefore, the improvement of energy and environmental performances are relevant targets because precious building materials such as marble have a significant impact on the environment. The aim of this paper is an analysis of a typical Sicilian marble (Perlato di Sicilia) to evaluate its energy and environmental performance. Marble plays an important role in the economy of Italy and has a global market share of 58% in terms of exports. For the main production areas of marble, relevant environmental performance data are missing except for one region (Tuscany-Massa e Carrara province). Per…
Interaction of construction costs and output in Latvia
2020
Growth of an economy is strongly linked with the growth of the construction sector. An increased construction output must influence the costs in this area. Analysis of the construction output and construction costs in Latvia for the time period since 2006 until 2017 shows an average effect. The main goal is to forecast construction costs and output in Latvia. Comparative analysis of costs and output dynamics was done, and a general trend can be proven, but heteroscedasticity is being observed. The effect of construction output on costs is limited in scale, but similar in general tendency and author offers his discussion for possible reasons for inconsistencies in construction sector changes.
Fontaines (Saône-et-Loire). Place de l’Église [notice archéologique]
2019
Le village actuel de Fontaines, situé à environ 8 km au N.-O. de Chalon-sur-Saône, se développe sur 1,5 km de long selon un unique axe E-O, depuis la montagne Saint-Hilaire à l’ouest, occupée au Néolithique puis durant l’Antiquité tardive et le haut Moyen Âge, jusqu’à l’église paroissiale Saint-Just, à l’est. Malgré une emprise limitée et contrainte par de nombreux réseaux existants, l’opération a permis de documenter l’environnement immédiat de l’église, occupé depuis l’Antiquité jusqu’à nos jours.
Le Clos de Vougeot (Côte-d’Or) : nouvelles observations sur les matériaux de construction et la chronologie du bâti médiéval
2009
Mithilfe sehr unterschiedlicherMethoden hat es sich diese Arbeit vor allem zur Aufgabe gemacht, bestimmte Phasen der Baugeschichte des Clos de Vougeot zu verstehen, um die Organisation und die Entwicklungen eines Zisterzienserhofsin Hinsicht auf diesozialen und historischen Wandlungen besser zu verstehen. Diese Studie bot ebenfalls Gelegenheit, die geologischen Eigenschaften der im Clos de Vougeot eingebrachten Baumaterialien genauestens zu untersuchen und neue Erkenntnisse zum Bau dieser Gebäude zu gewinnen und zu präzisieren.
