Management of demolition phases and related waste, in a building renovation project near Salerno, Italy
2020
Compliance with recent environmental regulations, the demolition phase, within the building replacement process, plays a decisive role, in terms of execution and management methods. The contribution addresses the problems related to the management of the site, in compliance with regulatory requirements for selective demolition and disposal of waste materials. Possible organisational and procedural solutions were investigated with particular reference to the phases of selective demolition (in compliance with Minimum Environmental Criteria), excavation, handling, treatment, recycling, and disposal of waste materials.
Investigating energy saving potential in a big shopping center through ventilation control
2019
Abstract This paper investigates energy saving measures for the ventilation system of large shopping centers. This kind of buildings is characterized by high yearly energy consumptions, because of the high level of operating hours and the frequent use of obsolete technologies. In the analyzed case studies, three big Do It Yourself (DIY) shops, located in Italy, are considered. Two different approaches are considered, they are aimed at reducing the annual energy consumption for the indoor air exchange of the sales area. The first considered retrofit solution consists in the installation of heat recovery exchangers, reducing the energy demand for the air thermal treatment without changing the…
Investigating Energy Saving Potential in a Big Shopping Centre through Ventilation Control
2018
This work shows an example of energy saving interventions on the ventilation system of a big shopping center. This kind of buildings is characterized by high energy consumptions, because of the high level of yearly operating hours and the use of obsolete technologies. In the case study, a big Do It Yourself (DIY) shop located in the southern part of Italy is analyzed, proposing two different approaches aimed at reducing the annual energy consumption for the indoor air exchange of the sales area. In the AS-IS scenario, a centralized HVAC plant, composed by six rooftops, is installed on the roof of sales area, working with fixed airflow value. The first retrofit solution involves the installa…
MANUTENZIONE DELL’AMBIENTE COSTRUITO: QUANTO RESTA DELLA NOTTE?
2021
Confrontando la manutenzione dell’ambiente costruito con la stessa attività riferita, in genere, ai prodotti manifatturieri, importanti caratteristiche specifiche emergono, sia nelle tecnologie di processo che di prodotto. Infatti, per le costruzioni lo stretto legame tra manutenzione e qualità acquisisce, in più, notevoli implicazioni di ordine sociale e collettivo, sia se applicata a edifici e spazi pubblici, sia se riferita all’edilizia residenziale privata. Nonostante ciò, tenendo conto della tendenza al “constructuring” che sembra indirizzare il futuro dell’edilizia sotto gli influssi della digitalizzazione, è ugualmente utile tener presente gli avanzamenti nel campo della manutenzione…
La motte médiévale de Drosnay (Marne) : résultats de deux sondages archéologiques
2011
Deux opérations de diagnostic réalisées en 2008 et 2009 ont permis de mettre au jour un segment du fossé d’enceinte d’une motte répertoriée depuis le XIXe s., ainsi que les restes d’un bâtiment en pierre sur sa partie sommitale. Le fossé a livré un mobilier dont la chronologie est centrée sur le XIIIe s. alors que le bâtiment n’est pas antérieur au XVe s. Les remaniements ayant affecté ce site sont nombreux. Dès le XVe s. d’importants travaux de remblaiement et de nivellement semblent modifier l’angle sud-ouest de la motte. Cependant, ce sont les terrassements contemporains qui ont irrémédiablement détruit la plus grande part des vestiges. Seule la basse-cour peut désormais conserver des ve…
Organy w kościele Świętego Krzyża w Bytomiu-Miechowicach. Historia i koncepcja rekonstrukcji
2018
Th article describes the history of organs in the noble Church of the Holy Cross in BytomMiechowice. Th largest amount of information has been preserved about the instrument built in 1905 by the Schlag und Söhne company from Świdnica. Ths organ was dismantled in the 1960s due to heavy mining damage and was later replaced by a temporary instrument. However, work is currently underway on the renovation of the temple. A proposal to recreate the historical organ is among the plans and is included in the ongoing design work.

Effect of two novel bio-based rejuvenators on the performance of 50% RAP mixes - a statistical study on the complex modulus of asphalt binders and as…
2019
An experimental study was conducted to evaluate the effectiveness of two bio-additives as rejuvenators on the properties of asphalt mixtures containing 50% RAP and their binder constituents containing 37% RAP binder. Before mixing, the rejuvenators were blended with fresh bitumen and the extracted and recovered RAP bitumen, and changes in the rheological properties of the binders were assessed using performance grading (PG) criteria. The results showed that both rejuvenators could improve the low-temperature performance of the aged RAP binder and restore its low-temperature properties. Master curves for the unaged, RTFO-aged, and PAV aged blends were constructed using both the Christensen-A…
Data Compression Approach for Long-Term Monitoring of Pavement Structures
2019
Pavement structures are designed to withstand continuous damage during their design life. Damage starts as soon as the pavement is open to traffic and increases with time. If maintenance activities are not considered in the initial design or considered but not applied during the service life, damage will grow to a point where rehabilitation may be the only and most expensive option left. In order to monitor the evolution of damage and its severity in pavement structures, a novel data compression approach based on cumulative measurements from a piezoelectric sensor is presented in this paper. Specifically, the piezoelectric sensor uses a thin film of polyvinylidene fluoride to sense the ener…
Pollutant Emissions in Ports: A Comprehensive Review
2021
In recent decades, maritime transport demand has increased along with world population and global trades. This is associated with higher pollution levels, including the emissions of GHG and other polluting gases. Ports are important elements within maritime transport and contribute themselves to pollutant emissions. This paper aims to offer a comprehensive yet technical review of the latest related technologies, explaining and covering aspects that link ports with emissions, i.e., analyzing, monitoring, assessing, and mitigating emissions in ports. This has been achieved through a robust scientific analysis of very recent and significant research studies, to offer an up-to-date and reliable…
