The acoustical characteristics of a room where the artistic performance is presented to the audience have a critical impact on the experience of both artists and spectators. It is important to know how the original aspects and the refurbishment works throughout the centuries are brought to the characterization of the sound field in such theatres, with positive and negative consequences. This paper presents the acoustical assessment of the Teatro Nuovo of Spoleto and the Teatro Alighieri of Ravenna, very important landmark centers for their historical and cultural activities. The acoustical characteristics have been gathered by placing the sound source on both the stage and orchestra pit, and the receivers in the stalls and balconies areas at different levels. It is of great interest to show the acoustical parameters of such Opera houses and some acoustical limits derived from intermediate interventions due to the need of the committees to allocate as many spectators as possible for income reasons. After an acoustic analysis of the existing conditions, the authors compare the acoustic behaviour inside the Teatro Nuovo of Spoleto using the image-source method (ISM) to investigate a change of ceiling configurations that occurred with the refurbishing works of the 20th century.

The wide variety of Opera taking place inside the São Carlos theatre of Lisbon suggested the authors to study the acoustic characteristics of three specific scenarios, which are given by the empty stage and by including the sceneries of Traviata and Italiana in Algeri. The florid artistical venues occurring throughout the centuries make this building an important icon for the capital city of Portugal. As such, an acoustic survey was carried out in order to define the acoustic parameters of this historical building and a numerical digital model was realized and validated by simulating three selected scenarios, whose results have been analysed and commented.

The variation of the room acoustic parameters measured in an auditorium is influenced by many variables such as the equipment, the operator, the position and orientation of the sound source and the microphones, and the post-processing method used for the calculation. An influence of fundamental importance is due to the thermo-hygrometric variables, which is commonly neglected. In this article, an experimental analysis concerning the influence of the temperature, relative humidity, and air velocity on acoustic parameters is presented. Thermo-hygrometric variables have been varied and the variation of several room acoustic parameters has been analized. A statistical analysis of the correlations has been obtained and used for the evaluation of the variation of the acoustic parameters by changing the thermo-hygrometric variables. Finally, a statistical analysis has been conducted to find correlations between room acoustic parameters and thermo-hygrometric parameters.

Decarbonisation and efficiency goals set as a response to global warming issue require appropriate decision-making strategies to promote an effective and timely change in energy systems. Conceptualization of change is a relevant part of energy transitions research today, which aims at enabling radical shifts compatible with societal functions and market mechanisms. In this framework, construction sector can play a relevant role because of its energy and environmental impact. There is, however, the need to move from general instances to specific actions. Open data and open science, digitalization and building data interoperability, together with innovative business models could represent enabling factors to accelerate the process of change. For this reason, built environment research has to address the co-evolution of technologies and human behaviour and the analytical methods used for this purpose should be empirically grounded, transparent, scalable and consistent across different temporal/spatial scales of analysis. These features could potentially enable the emergence of “ecosystems” of applications that, in turn, could translate into projects, products and services for energy transitions in the built environment, proposing innovative business models that can stimulate market competitiveness. For these reasons, in this paper we organize our analysis according to three levels, from general concepts to specific issues. In the first level, we consider the role of building energy modelling at multiple scales. In the second level, we focus on harmonization of methods for energy performance analysis. Finally, in the third level, we consider emerging concepts such as energy flexibility and occupant-centric energy modelling, considering their relation to monitoring systems and automation. The goal of this research is to evaluate the current state of the art and identify key concepts that can encourage further research, addressing both human and technological factors that influence energy performance of buildings.

The paper investigates the optimal acoustic characteristics for theatres that include animals in their shows, especially horses, seeking for the maximum comfort both for people and for animals. Recommendations and indications might become guidelines for a possible architectural acoustic design. The architectural elements to influence the room acoustic response are indicated and numerous objective parameters to identify and describe the trend of the requested sound field are described. Having considered a good acoustic field for animals when the early reflections are usually present but late reflections are rare, the Reverberation Time at middle frequencies is introduced. The range of frequencies is extended from 63 to 8000 Hz. In the paper it is reported that optimal acoustic conditions are reached when the gross volume of the theatre should not exceed approximately 1800 m3, with high level of intelligibility (more than 60%) and Early Decay Time of 1.1 s. The interest to design theatres to host animals arises from some existing buildings which seldom host animal shows together with musical performances, which represents a hybrid solution between theatres and circuses. These buildings might help especially young people having some mental disorders to improve their living quality. One example is represented by the Emilia Bosis Foundation in Verdello (Bergamo, Italy), a non-profit organization that deals with people with mental disorders, to develop a space where to set up projects that include arts, animals ( horses in particular), and other cultural and social activities.

The Eszterháza Opera House was a theatre built by the will of the Hungarian Prince Nikolaus Esterházy in the second half of the 18th century that had to compete in greatness and grandeur against Austrian Empire. The composer that inextricably linked his name to this theatre was Haydn that served the prince and composed pieces for him for many years. The Opera House disappeared from the palace complex maps around 1865 and was destroyed permanently during the Second World War. This study aims to reconstruct the original shape and materials of the theatre, thanks to the documents founded by researchers in the library of the Esterházy family at Forchtenstein, the Hungarian National Library, and analyze its acoustic behavior. With the 3D model of the theatre, acoustic simulations were performed using the architectural acoustic software Ramsete to understand its acoustical characteristics and if the architecture of the Eszterháza Opera House could favor the Prince’s listening. The obtained results show that the union between the large volume of the theatre and the reflective materials makes the Opera House a reverberant space. The acoustic parameters are considered acoustically favorable both for the music and for the speech transmission too. Moreover, the results confirm that the geometry and the shape of the Eszterháza Opera House favored the Prince’s view and listening, amplifying onstage voices and focusing the sound into his box.

The reduction of energy usage and environmental impact of the built environment and construction industry is crucial for sustainability on a global scale. We are working towards an increased commitment towards resource efficiency in the built environment and to the growth of innovative businesses following circular economy principles. The conceptualization of change is a relevant part of energy and sustainability transitions research, which is aimed at enabling radical shifts compatible with societal functions. In this framework, building performance has to be considered in a whole life cycle perspective because buildings are long-term assets. In a life cycle perspective, both operational and embodied energy and carbon emissions have to be considered for appropriate comparability and decision-making. The application of sustainability assessments of products and practices in the built environment is itself a critical and debatable issue. For this reason, the way energy consumption data are measured, processed, and reported has to be progressively standardized in order to enable transparency and consistency of methods at multiple scales (from single buildings up to building stock) and levels of analysis (from individual components up to systems), ideally complementing ongoing research initiatives that use open science principles in energy research. In this paper, we analyse the topic of linking design and operation phase’s energy performance analysis through regression-based approaches in buildings, highlighting the hierarchical nature of building energy modelling data. The goal of this research is to review the current state of the art of in order to orient future efforts towards integrated data analysis workflows, from design to operation. In this sense, we show how data analysis techniques can be used to evaluate the impact of both technical and human factors. Finally, we indicate how approximated physical interpretation of regression models can help in developing data-driven models that could enhance the possibility of learning from feedback and reconstructing building stock data at multiple levels.

Coconut fibre insulators represent an insulating material considered as “exotic”, which clashes with the scepticism of his thermo-hygrometric behaviour, particularly in the case of covering technology such as green roofs, which is a technological solution often adopted in the case of sustainable buildings or nearly zero energy building. Green roofs represent a valid constructive solution with high thermal performances, adopted both in existing and new buildings. The purpose of the research regards the study of the thermo-hygrometric behaviour of the concrete (CLS) and Cross-Laminated Timber (CLT) slabs, insulated with coconut fibreboards (CF) such as an alternative of synthetic insulator, referred to 10 different green roofs scenarios. The results show that coconut fibre insulations are equally comparable to natural and synthetic materials, and the doubts for their applications, including the green roofs, are related to technological solutions for the implementation in the market and their diffusion between the buildings materials, rather than their hygrothermal features.

This paper compares two acoustical projects, applied to the S. Dominic church of Foligno and Imola, which are subject to a permanent and temporary conversion respectively, to places dedicated for listening to live music. Sets of measurements have been undertaken before the acoustical treatments in order to calibrate the digital model; in Foligno, the measurements have also been performed after the installation of the acoustical features, to check if the aims have been achieved. Between the proposed acoustical projects, only one has been realized in Foligno, with the artistic activity still running inside the auditorium. The challenge to adjust the acoustics of reverberant rooms like churches to host musical venues has been achieved with a good quality of sound perception. In particular, in S. Dominic church of Foligno, the goal has been hit after many digital simulations that calibrated the redirection of the sound towards the sitting areas.

In 2014, an SMPTE report stated that sound consistency between dubbing stages and performance venues was not respected. SMPTE technical commission studied this issue in 3 commercial cinemas and 3 dubbing stages in Hollywood using the impulse response method. This lack in sound consistency is probably imputable to the use of a wrong calibration system (RTA + Pink Noise Method) that is time-blind and does not mimic the perceptual listening of the human being. A campaign of measurements has been conducted in Rome to test the acoustic properties of a dubbing stage room and a cinema performance room. Two measurement systems were implemented: One for the extraction of ISO 3382 parameters (Omni, Binaural, Soundfield) and one for studying the spatial distribution of sound in the room (EigenmikeTM).

The need for capturing the acoustic properties and spatial information of significant ancient theatres became very important in the last years. Particularly, the knowledge of sound propagation became very important during the design or refurbishment of historic theatres and opera houses. Theatre 1763 in Villa Aldrovandi Mazzacorati, in Bologna (Italy), is chosen as a remarkable example. This is a small private theatre built by the Aldrovandi family during the 18th Century inside the historic Villa Aldrovandi Mazzacorati. The theatre maintains its original shape, indoor materials and furnishings as chairs. For this reason and its peculiarities, the theatre was deeply investigated by several architects, but no acoustic measurements were extensively conducted within the hall. This article reports the results of two measurement campaigns which were conducted in different periods and with different methodologies, to evaluate the variability of the acoustic parameters and determine intrinsic characteristics of this unique small theatre.

This study reports history and the original architectural design of the Miners’ Theatre in Idrija. This theatre is usually considered to be the oldest such building in Slovenia and in 2001 it was declared a cultural monument of national importance. The building shape was typical of numerous small stand-alone theatres throughout Central Europe in the 18th century. The original design was later changed several times until it has reached the actual aspect. To analyse the acoustic characteristics of the current room (often named “Film Theatre”), an acoustic survey was carried out and several acoustic parameters defined in the ISO 3382-1 standard, were calculated and analysed. To study the acoustic characteristics of the theatre in its original shape, a numerical model was realized and properly validated. The simulations of three different scenarios were performed and the results obtained from the simulation have been analysed and commented.

Soundfield diffuseness in rooms is considered a fundamental aspect of a high-quality room acoustics. Since early studies by Hodgson up to more recent studies of Shtrepi and Embrechts, it was shown that high levels of sound diffuseness could guarantee blending of music, as well as spatial sound perception by listeners, and this could enhance the global indoor acoustic quality. Conversely, Italian-style Opera houses represent an important architectural place, in which the special features of the rich decorations, and the specific characteristics of the volume, give a unique atmosphere, including a peculiar psycho-acoustics impression. However, some geometric properties of the opera houses could influence the global acoustic perception. The shape of the marmorino wall on the stalls, as well as the parallelism of the lateral walls in the boxes, often causes a lack of spaciousness and sometimes in the worst cases provokes focalization. This phenomenon leads to design special devices that could be inserted in the theatres, to avoid focalization, even if they are rarely accepted. This article deals with the design of some acoustic diffusing panels and their functioning in three different theatres, combining both acoustics needs with architectural constraints. The article starts analysing and commenting on the issues that resulted from the measurements conducted in an Italian opera house. In the following step, three examples of the design of diffusing panels are proposed. Finally, the results of diffusion and scattering coefficient of panels realized in the last theatre considered here are reported.

During the renovation of auditoria and concert halls, the acoustic quality is normally evaluated from measurements of impulse responses. One possibility for evaluating the acoustic quality from the measurements (the simulations) consists of convolving anechoic music with the measured (or simulated) impulse responses. In this way, a psycho-acoustic test is achieved using a virtual sound field representation. The listening room ‘Arlecchino’ at the University of Bologna includes ambisonics (up to fifth order) and stereo-dipole playback for virtual reproduction of sound in rooms. In this article, the effectiveness of the listening room ‘Arlecchino’ is first analysed, comparing acoustic parameters obtained from binaural impulse responses measured in some opera houses (in Italy) and auditorium (in Japan) with those virtually measured after the virtual reconstruction obtained in the listening rooms. The similarity between real and virtual sound fields, has been evaluated by comparing different acoustic parameters calculated by real and virtual sound fields, in four halls in different configurations, by means of the stereo-dipole method. In the second part of the article, the listening room was used to analyse the variation in interaural cross-correlation measurements in rooms obtained considering different anechoic sound signals convolved with the binaural impulse responses, to quantify the variation of the interaural cross correlation with different motifs. For this purpose, two different musical instrument digital interface musical motifs, very different from each other for their music characteristics, have been considered. Moreover, for each musical motif, different sound characteristics (i.e. different musical instruments) were considered, to consider both the rhythmic and timbre aspect.

This study focuses on the introduction of different types of insulation materials into existing building systems in Europe, where the chosen scenarios differ by climate zone and according to the Köppen climate classification. The insulation materials used are specifically: natural fibre materials, mineral fibre materials and artificial materials. The analysis in question was based on the assessment of the risk of interstitial condensation between the existing masonry and the insulation and the WCI [Kg/m2] (Water Content in the Insulation), through various simulations in dynamic mode, over a reference period of 10 years prior to the energy upgrading intervention. The case study buildings were taken from TABULA and divided by climatic zone, for the years of construction from 1945 to 1969 related to the building typology of single-family houses, wherein each building system the insulation was placed towards the warm side with a fixed thickness of 5 cm. The simulations concerned: a) the application scenario, b) the type of stratigraphy chosen, (c) exposure of the existing building system. The outputs generated by the simulations provided the data to determine in which type of building, depending on the insulating materials, interstitial condensation is formed or not. It was shown that only for the climate zones of the cities of Oslo and Brussels, associated with their own building typologies, for the insulating materials: mineral and natural, there is the formation of interstitial condensation.

A strategy for improving the buildings energy efficiency is to diminish the energy demand for space heating and cooling. The European Directive has established a high standard of thermal insulation, involving stringent limits for building energy performance. However, such approach determines an increase of the cooling energy demand and noteworthy overheating of indoor spaces in the summer period. This study investigates through dynamic thermal simulations the effectiveness of new thermal insulation materials, such as Vacuum Insulation Panels (VIPs) and Phase Change Materials (PCMs), on reducing heating and cooling energy demands, as well as guaranteeing the thermal comfort into a test room located in three different locations (Catania, Rome and Wien). The energy demand for space cooling and heating have been evaluated for the different facade configurations, as well as the attainable indoor thermal comfort. The outcomes of the simulations in air-conditioned spaces highlight that the wall configurations that adopt VIPs allow reducing the heating energy needs but may increase the cooling energy needs. Remarkable differences are not detected for the heating and cooling energy demands when the PCMs are used. The daily fluctuation of the indoor operative temperature and the adaptive comfort model suggest that the PCM placed on the inner side of the walls shows a good thermal performance. The outcomes of the study outline the strengths and weakness of the analyzed facade configurations, which may help designers in the search for suitable solutions.

To reduce the incidence of greenhouse gas emissions, radical measures need to be adopted in the most pollutant sectors, among which the building one, where actions can be undertaken, involving both the passive (envelope) and the active (thermal plants) sections. In this framework, the aim of this paper was to elaborate and test a suitable procedure to measure one of the characteristic parameters of the envelope, the thermal transmittance of the opaque components. A codified procedure has been exploited, using instruments and experimental techniques able to overcome most of the drawbacks (e.g. long period of measurement) which often have to be dealt with, during field measurement of thermal transmittance of opaque building envelope structures. The technique was exploited to measure wall thermal transmittance of different buildings located in the city of Reggio Calabria (Italy),

Starting from the analysis of the problems that characterize the Italian suburbs, the application of a Smart Methodology to a real peripheral area is presented. In literature, several studies underline the urgent request of the city's periphery, enhancing local and national projects to increase the quality of life in the suburbs. In this framework, authors propose a multifunctional centre development, characterized by modern technologies (both structural and plant) to implement energy efficiency and social aggregation, in line with the citizen's needs. Once the simulation model of alternative solutions, such as construction type, energy system and social services, was elaborated in Matlab/Simulink, the application of a smart methodology was necessary to draft the priority ranking of the various strategies. Results highlight which solution obtained a positive impact on the overall smart axes, providing a useful approach for designers to plan a sustainable and smart project.
