METHODOLOGICAL EXPERIMENTATION FOR RENOVATION OF SPREAD BUILDING HERITAGE: A CASE STUDY IN NAPLES’ METROPOLITAN AREA
No full textWithin building renovation interventions, a deep knowledge of the building and the context in which it is placed is a key factor in order to respect, in the upcoming intervention, the character of the existing building. For this reason, during the investigation phase it is very helpful to follow a standard and univocal procedure, consisting in simple steps, allowing to identify, at various scales (urban, building, technological, etc.) the invariant elements to be repeated in the project. This paper presents the application of a possible methodology to a real case belonging to the spread building heritage in Naples’ suburban area
Ri-conoscere il costruito attraverso l’analisi tipologica: un caso di studio nell’area metropolitana di Napoli
No full textBefore carrying out any building refurbishment intervention, it is necessary to gather as much information as possible about the building itself and the built context surrounding it. This is a key factor in order to preserve the character of the built area in the design of the renovation intervention. For this reason, the first step to take is a field and archive survey to collect information and acquire knowledge about the existing shapes, materials, techniques and technologies. To do this, it may be helpful following a standardized procedure, consisting in simple steps, which allows identifying, at various scales (urban, building, technological, etc.) the invariant elements to be conserved, preserved and repeated in the project. This paper presents the application of a possible typical methodology to a real case belonging to the spread building heritage in Naples’ suburban area
How Circular is an Italian Apartment Building? Testing of a Whole-Building Circularity Indicator
No full textCircular economy (CE), focused on closing the material loops, turns out to be relevant in
the building industry to improve the construction process and reduce waste. Assessing the
circular performance of buildings reveals the current level of achievement and future areas of
improvement, hence aiding in transitioning from a linear to a CE based construction industry.
However, this can be very complex, especially due to absence of a universally accepted Circularity Assessment Framework. Bearing that, a comprehensive CE assessment tool called
Whole-Building Circularity Indicator (WBCI) is being developed at Engineering Department
of University of Campania. This study tests and validates the first version of the freshly released WBCI using an existing apartment building in Southern Italy as a case study. The data
is collected through building documents (detailed drawings, specifications) and site visits,
and then modelled in BIM to perform a rigorous analysis. The results show that the apartment
building does not perform well in circularity and scores very low (0.274). Excessive use of
virgin materials, linear design approach, poor adaptability and disassembly potential after
the end of life are the leading causes for this low score. The space plan turns out to be the
most circular system among different building layers. The validation also uncovers the positives and negatives of the tested model. Finally, the study recommends practical strategies to
improve the circular performance of residential buildings. With these advantages, this paper
contributes to the much-anticipated debate on the measurement of CE in the building industry and can help construction practitioners estimate how advanced they are in the process of
transition from linear to circula
SULLE TECNOLOGIE PER IL MONITORAGGIO NON INVASIVO DELL'UMIDITA' NELLE MURATURE
No full textGran parte delle tecniche esistenti per la misurazione del contenuto di umidità nei paramenti murari prevede campionamenti, perforazioni e inserimento di sonde. Tali pratiche non possono essere utilizzate in edifici appartenenti al patrimonio culturale poiché comprometterebbero l’integrità del manufatto. Viene qui presentata una panoramica critica dei metodi non-invasivi allo stato disponibili
MOISTURE CONTENT ESTIMATION IN YELLOW NEAPOLITAN TUFF AND CLAY BRICK BY TDR
No full textTime Domain Reflectometry (TDR) is a proven technology for the evaluation of soil moisture,
which is increasingly finding application in the field of moisture measurement in porous building materials. In
this work TDR technique is used to estimate water content of two building materials commonly used for
masonry: yellow Neapolitan tuff and clay bricks. The two specimens were first instrumented with a classic
three-rod TDR probe and then saturated by immersion. The moisture measurements were carried out during
the drying phase, coupling TDR readings with gravimetric determinations of water content. Then, empirical
relationships linking water content (gravimetrically measured) to the dielectric permittivity of the material
(obtained by TDR) were retrieved. In fact, TDR response strongly depends on the water content of a material
since the dielectric permittivity of water is about 40 times greater than the one of the dry material. The found
calibration curves have a clear trend and confirm the suitability of TDR for the estimation of water content in
porous building materials
