The first experimentation was done in situ during a restoration campaign. To improve the understanding of the phenomena, it was planned to carry on some experiments on porous materials that are homogeneous as much as possible. A fired clay brick and a sand stone pietra serena have been used to apply the contact sponge technique and to monitor the induced effects by IRT in a controlled environment

I componenti trasparenti sono infatti un elemento fondamentale dell\u2019involucro edilizio in grado di svolgere tradizionalmente pi\uf9 funzioni contemporaneamente: ingresso di energia, ingresso di luce, visione della contesto ambientale esterno. L\u2019innovazione tecnologica dei materiali permette attualmente di aggiungere anche una ulteriore funzione che \ue8 quella della produzione di energia ossia della trasformazione dell\u2019energia radiante solare in energia elettrica e energia termica. Ci\uf2 risulta di notevole interesse in relazione alla necessit\ue0 di realizzare entro pochi anni, sulla spinta della legislazione nazionale e europea, edifici che non consumino energia (Zero Energy Building ZEB) o che ne consumino molto poca (Near Zero Energy Building NZEB). Si sono presi in considerazione elementi di involucro innovativi (attivi e passivi) e la loro integrazione nel bilancio energetico dell'edificio. Pi\uf9 specificamente nel campo del sistemi produttori di energia di tipo fotovoltaico integrati nell\u2019involucro edilizio (Building Integrated PhotoVoltaic BIPV) si \ue8 attuata una estesa indagine di mercato sulle diverse tipologie di prodotti e sulle loro caratteristiche. Si sono individuate al momento attuale le tecnologie pi\uf9 concretamente applicabili nel contesto della progettazione delle residenze e degli edifici del terziario. Parallelamente si \ue8 svolta una attivit\ue0 sperimentale e si sono predisposti alcuni campioni con la collaborazione dell\u2019azienda UnionGlass di Motta di Livenza (TV) e del laboratorio ENEA UTEE ERT. Si \ue8 scelto di analizzare nel dettaglio un elemento BIPV composto dalle stratigrafie pi\uf9 diffuse sul mercato. Si tratta di un vetro laminato al cui interno viene inserito un strato di celle fotovoltaiche. Si sono caratterizzati tali campioni rispetto alle loro propriet\ue0 termo-fisiche e radiative in laboratorio. Presso il Laboratorio di Fisica Tecnica ambientale e presso il Laboratori ENEA ERT \ue8 stata determinata la trasmittanza termica. Presso il Laboratorio Fraunhofer Institut f\ufcr Solare Energiesysteme ISE di Friburgo si \ue8 proceduto alla determinazione del fattore di guadagno solare. Infine le propriet\ue0 ottiche e radiative degli elementi dei sistemi studiati (coefficienti di riflessione, trasmissione ed assorbimento) sono state misurate attraverso analisi spettrale alle varie lunghezze d\u2019onda presso la Stazione Sperimentale del Vetro di Murano Venezia. \uc8 stato messo a punto poi un modello numerico al fine di stimare le caratteristiche ottiche e termiche dell\u2019 elemento BIPV. Tale modello si base sulla descrizione del sistema con equazioni differenziali le quali sono state risolte con la tecnica delle differenze finite. Utilizzando tale modello sono state effettuate le stime dei parametri di trasmissione solare e trasmittanza del modulo BIPV, e i valori sono stati confrontati con i risultati sperimentali sintonizzando il modello numerico. A partire dai dati ottenuti dalla misura sperimentale e dalla modellazione numerica per il singolo componente fotovoltaico si \ue8 analizzata utilizzando un software di simulazione dinamica dell\u2019edificio l\u2019integrazione del sistema di produzione fotovoltaica sull\u2019edificio. Le analisi sono state fatte su un modello rappresentante un ufficio con una finestra esposta a Sud con moduli BIPV a diverse frazioni di area libera dalle celle

Also historical buildings are demanding attention from an energetic standpoint, as the most part of them needs renovation interventions. Due to their peculiar characteristics, these kind of buildings require advanced, non-invasive and non- intrusive survey techniques such as infrared thermography. In this paper the ancient church of San Vito alla Rivera, located in L'Aquila, has been inspected with infrared thermography. Data obtained from the survey have been used to improve the reliability of numerical energy simulation software, as energy modelling can support and orient the renovation process of the building

This change had a significant impact since early 2019, on the materials and systems that can be used in the construction sector. In 2020, the global pandemic caused by the diffusion of the COVID-19 virus represented a new challenge for the industry, with implications on programme certainty, material procurement, workforce management, moving towards offsite manufacture. The development of the Trent Brick Panel is set against this historical and social context. The envelope prototype is the opportunity for innovation that follows the turn of events. The offsite manufacturing of glass-reinforced concrete panel, mimicking several finishes, is the result of a design investigation carried out with the market-leading actors: developers, main contractors, subcontractors, engineering consultancies, architects, local authorities and warranty providers. The research aims to give an overview of the design principles, sequence and buildability study, assessed weathering performance according to CWCT Sequence B test and fire performance.

However, the existing buildings represent the major part of the building stock and an interesting challenge is to transform it in NZEB. In Italy this challenge is remarkable: existing buildings stock (mainly residential) is also historic, so it\u2019s subject to environmental constraints or architectural-artistic value, and it\u2019s influenced by specific regulations and methods of intervention for refurbishment. The challenge becomes even more important and concerns both the building shell and the systems: retrofitting introduces not originally present in the complex; retrofit is not covered in the maintenance, since it represents an upgrade, an adaptation of the building, specifically in relation to energy efficiency, but also, by extension, other functions / features pertaining to the environment and sustainability. A case study of a radical refurbishment of an historical building is Ca' S. Orsola in Treviso. It is ruled by the Historical and Architectural Veneto Regional Authority. The building has been transformed into a prestigious residential complex by a major renovation that was aimed primarily seismic and energy upgrading. The energy and environmental performance of building have been analyzed by numerical simulation and experimental measurement in the EBC IEA Annex 56 [1] context with the aim to verify that intervention strategies respect to the reduction of energy consumption, the minimization of CO2 emissions and maximizing the use of sources of renewable energy

Recently the life cycle analysis (LCA) is commonly used as check instrument in design of new buildings, but it is not used yet regularly in existing redevelopment, most of all if it is about a very old building as the below example. The life cycle assessment was introduced in 1993 by the SETAC (Society of Environmental Toxicology And Chemistry) and it is a method of systematic analysis that values the environmental impacts of a product, the process of production and its activities during all the life cycle. The life cycle of products surrounds all the phases of the production and also the use and the end of the components of the process itself. The analysis starts from the extraction of the natural resources and the production of energy for the productive process; material and energy are parts o...

The concept involves combining technologies of integrated radiant piping with an evaporative cooling tower or an electric heater, and the creation of a smart shape that reflects the radiant temperature of each pipe everywhere inside the structure.
The “Dome Control System” measures the physical parameters behind the prototype. It’s an environmental control station through which Arduino senses the environment by receiving inputs from many sensors. Different kinds of sensors have been used to monitor the water temperature of the cooling tower or of the electric heater, the water flow rate of the radiant piping, the temperature, the relative humidity and the mean radiant temperature inside and outside the Dome, even using unprecedented methods to sense the mean radiant temperature.
The combination of this new and emergent technologies provides operation and control of the physical parameters we are interested in investigating, so as to facilitate research into the perceptions of comfort inside the Dome.
