No full textA comparison between environmental sustainability rating systems LEED and ITACA for residential buildings
No full textThe paper presents a comparison between two different rating systems to evaluate buildings sustainability:
LEED (USA) and ITACA (Italy), thanks to the application of both methods to two residential
buildings located in Italy.
The LEED green building rating system encourages an integrated design approach, with a points
scheme that allots credits for building design features deemed to improve sustainability, which includes
reductions in energy use, improvements in indoor environment quality, protection of the construction
site, reduction in water consumption and use of sustainable materials.
ITACA procedure, the environmental quality rating system adopted in Italy, consists of the compilation
of a group of worksheets, one for each different performance indicator, at the aim of describing the
building environmental quality, including the maintenance of indoor comfort during the entire life cycle.
The chosen buildings are located in central Italy; they are both energy efficient and designed according
to the principles of bioclimatic architecture, even if they are characterized by different features. Five
common areas (site, water, energy, materials, indoor environmental quality) were identified in order to
compare the two methods and to normalize their score; this original approach can be transferred also to
the comparison of other building environmental assessment tools.
The comparison allows to prove the main features of both schemes. Even though the two procedures
give different importance to the various areas, the analysis show a proportionality between the
respective normalized final score for the two examined buildings
Il Paleolitico superiore in Maremma: modalità insediative e paesaggi preistorici fra la Grotta del Sambuco e le coste del Tirreno
No full textIl contributo illustra la distribuzione e le
caratteristiche delle evidenze del Paleolitico
superiore in Maremma (GR). Il censimento
dei siti editi, comprendente sia dati di scavo
che raccolte di superficie, è stato effettuato
per un transetto di studio al cui centro si trova
Grotta del Sambuco (Massa Marittima)
e che dalle colline metallifere si estende fino
all’attuale arcipelago. Per l’area in esame si
propongono ricostruzioni del paesaggio preistorico
individuando le tracce di elementi relitti
che, nonostante le trasformazioni oloceniche,
identificano il paesaggio del Paleolitico.
Particolare attenzione è stata dedicata alle
trasformazioni della linea di costa. Questa ha
raggiunto durante il massimo glaciale la quota
batimetrica di - 120 mt dando luogo alla
formazione di una sorta di paleo golfo che si
estendeva con varie conformazioni durante le
diverse fasi, dalla fine del MIS 3 al MIS 2, fino
ad includere l’Isola d’Elba e l’Isola di Pianosa.
In questo scenario sono state ipotizzate le relazioni
fra i siti dell’area interna e quelli costieri
per comprendere le diverse strategie insediative
del Paleolitico superiore in un’ottica sia
sincronica che diacronica.The paper presents the distribution and
the characteristics of Upper Palaeolithic evidence
in Maremma district (GR). The gathering
of data related excavations and surface
collections are used to investigate the prehistoric
landscape of a transect which includes the
inner territory of the Sambuco Cave (Massa
Marittima) and it extends till the actual Tuscan
archipelago. Beyond the Holocene transformation
the study area preserved some
relict features of the Palaeolithic landscape.
Attention has been paid to costal changes, during
the LGM the sea level get down till -120
mt and the coastland included the actual Elba
and Pianosa Islands assuming different shapes
during MIS 3 and MIS 2. In this scenario
the relationship between inland and coastland
sites has been investigated in order to explore
the Upper Palaeolithic settlement strategies in
synchronic and diachronic perspectives
L'affidabilità diagnostica della citologia preparatoria nella patologia nodulare tiroidea: confronto con la diagnosi istologica intraoperatoria e con quella definitiva
No full textIntra-site spatial analysis at Sambuco Cave: testing digital 3D approach for the interpretation of Upper Palaeolithic behavioural strategies
No full textSambuco Cave, located in central Italy, preserves a stratified sequence from the Upper Palaeolithic to the Neolithic, making
it an important archaeological site. This research combines traditional excavation data with Digital Heritage methodologies to enhance the understanding of site formation and spatial organization within the cave. A 3D GIS-based workflow integrates photogrammetric documentation, lithic analysis, and spatial modelling to reconstruct prehistoric behaviours and identify activity zones. The study highlights the importance of virtual reconstructions in clarifying stratigraphic relationships and interpreting the cave's usage. Results suggest a focused, task-specific occupation pattern, emphasizing short-term use, possibly related to hunting and toolmaking. This innovative approach provides valuable insights into Upper Palaeolithic settlement strategies and offers a new perspective on the spatial organization of prehistoric sites. At present, this paper represents an experimental 3d analytical approach presented here as a methodological test
A Generalization of the Cors Method to Determine Cepheid Radii: Theory and Application
No full textThe CORS method for the empirical determination of the radii of pulsating variables (Caccin et al., 1981; Sollazzo et al., 1981) is discussed in the framework of the quasistatlc approximation to the variations of the atmospheric parameters (Unno, 1965) and reformulated in a way that does not make direct use of theoretical calibrations of the photometric system in terms of model atmospheres. The radii calculated with this approach are in good agreement with those previously obtained by means of Pel's calibrations of the VBLUW system (Sollazzo et al.,1981) which lead to a period-radius relation coinciding, within the errors, with the theoretical one (Cogan, 1978) and, consequently, mass determinations consistent with pulsational masses (Cox, 1979). The method can be immediately applied to any other multicolour system, and very promising preliminary results are obtained by using recent UBV data by Gieren (1982)
