The growing demand for electric energy requires smarter and quicker distribution systems. In urban contexts, a of power to various classes consumers, according their demands, is possible through compact sorters. Since this type device must be protected from unwanted access by people, wildlife inclement weather, protection placed around the main components. When deployed in areas, housing can built using solid panels. However, there risk overheating vital costly parts system with possibility...

In a world increasingly aware of the environmental cost current production/ consumption model, use sustainable practices to reduce our impact as society becomes imperative. One way this is increase reuse materials that are considered, by definitions ”waste”, at their end life. End-of-Life Household Materials (EoLHM) can be defined household waste still possess exploitable properties, thus making them suitable for reuse. There several studies in literature address recycling these materials....

The circular economy model is based on the 4R framework—reduce, reuse, recycle, and recover. While recycling was primary focus in past, shortage of raw materials desire to reduce carbon footprints have led a change focus: end-of-life are now considered resources rather than waste. When discharged, still possess properties that can be exploited. For this reason, comprehensive characterization reusable mandatory waste increase material availability. reuse materials, such as surgical masks,...

This paper investigates the relationship between Indoor Environmental Quality index (IEQ): thermal comfort and indoor temperature trend in moderate environments, buildings that belong to Class A with reference Energy Performance of Building Directive (EPBD). The work consists measurement IAQ energy efficiency a residential building located centre-north Italy, namely Ravenna. results measurements, as well PMV-PPD indexes, are presented commented. These indexes could be criteria test if EPBD...

To reduce energy consumption for space heating, a coordinated action on supply, building fabric and occupant behavior is required to realize sustainable improvements. A reduction in district heating supply temperature an interesting option allow the incorporation of renewable sources distribution losses, but its impact final users must be considered. This aspect especially critical as most European countries feature old stock, with poor insulation systems designed high-temperature operation....

The control of noise propagating along ventilation system ducts has always been an important issue in the building and vehicle sectors. This problem is generally tackled by selecting noise-reducing components with a suitable transmission loss, possibly verifying their effectiveness at later time. aim this article to characterize nature propose design approach focusing directly on perceived effect, that is, sound pressure level downstream outlet. Because emission depends various generation...

Sandwich structures are manufactured using multiple combinations of materials for core and laminates. The real performances influenced by variability in the composing layers even uncertainties introduced while bonding them together. Therefore, experimental tests usually preferred way to assess most important parameters required develop characterize product, main downsides lying their cost time consumption. This work explores a practical application wave propagation approach means case study,...

The Lombardy Region and the Construction Technologies Institute of National Research Council Italy are promoting development an innovative coating nano-material for building retrofitting. research aims at obtaining a material with higher sound absorption features when compared to conventional plasters, as well fair thermal insulation performances. In both design testing stages, it is important identify measure key acoustic parameters. This article presents characterisation new in terms by...

Clay hollow brick walls are still popular in building industry, but the prediction of their sound insulation properties is not straightforward due to inhomogeneous and anisotropic characteristics. In this article, a classic approach has been used determine transmission coefficient walls, assuming an orthotropic behaviour deriving mechanical dynamic characteristics from datasheet information. Different types with horizontal vertical mortar joints have analysed. Experimental measurements...

Composite panels are being increasingly used in many applications because they can combine several interesting properties, such as high load-bearing capacity, low weight, and excellent thermal insulation. Different core materials be for composite sandwich panels, like polystyrene, mineral wool, polyurethane, glass or rigid phenolic foam, which is considered the plastic foam with best fire-proof properties. During research development phase, use of simulation tools often required improvement...

With the world facing urgency of energy transition, development efficient and quiet electrical infrastructures is topical importance in construction environment future. The problem noise from power distribution systems often underestimated, although several works literature underline effect disturbance on population, especially concerning low frequency range. This paper overviews issue low-frequency generated by substations, experimental characterization source to possible mitigation...

The paper presents the results of a critical analysis most important prediction methods radio-interference and acoustic noise produced by power transmission lines available in technical literature. A code has been implemented MATLAB environment to improve quality predictions, preliminary validation tool are presented. Particular attention is given applicability non-conventional geometries lines.

One of the tasks scholars and scientists is to highlight values cultural heritage, a great patrimony that all new generations should be acknowledged. aspects explored besides construction restoration historical buildings, especially Opera theatres, acoustics. This article deals with acoustic investigation performed in relation Teatro Grande Brescia. The outcomes have been analyzed by following both standard requirements stated ISO 3382-1 creating an overlay video shows real-time impulse...

From a circular economy perspective, the acoustic characterization of steelwork by-products is topic worth investigating, especially because little or no literature can be found on this subject. The possibility to reuse and add value large amount kind waste material lead significant economic environmental benefits. Once properly analyzed optimized, these become valuable alternative conventional materials for noise control applications. main properties investigated by means four-microphone...

Thermal solar systems are interesting solutions to reduce CO 2 emissions and gradually promote the use of renewable sources. However, sizing such analysing their behavior still challenging issues, especially for trade-off between useful energy maximization stagnation risk minimization. The new EPB (Energy Performance Buildings) standard EN 15316-4-3:2017 offers several methods evaluate performance a forced circulation system. One them is dynamic hourly method that must be used together with...

With energy efficiency regulations coming into force, the retrofitting of existing plants has become mandatory in many European countries. The application thermostatic radiator valves is a cheap, effective solution case radiator-based hydronic plants, but it requires distribution system to be re-engineered and, some situations, further adjusting devices added. In this paper, behaviour vertical heating been simulated with aim analysing outcome different hydraulic balancing strategies and...

Overhead high-voltage lines are a common choice for power transmission, but their planning, installation and management often challenging tasks because of the surrounding public interest importance as critical infrastructures.
