“…The numerical results are affected by limitations from the software features affecting also their assessment and their mathematical post-processing [23]. As a matter of fact, it should be pointed out that not all the applications could evaluate all the parameters and it is very important from a probabilistic point of view [24], especially in historic buildings [25]. Even if the aim of the study is not to make a ranking list, these lacks affect the final judgment on some of the software.…”

The evaluation of room acoustics characteristics in rooms has been thoroughly described in several papers since the 60-is. Moreover, the ISO 3382 standard describes several acoustic parameters and their measurements. However, there is only a few information about the methods of pre-processing the impulse responses that are required before calculating those acoustic parameters. If the final goal of measuring the acoustical behaviour of a room is to compare it to others or to create databases, reliable and comparable data must be obtained, no matter the way they have been measured. At the Engineering Department of the University of Bologna, several tests, with the same starting data set, have been performed to compare the results given by the most commonly used PC applications, in order to identify and quantify any possible incongruity. In this paper, the main processing methods (based on Lundeby, Chu) are analysed. Moreover, they are compared with the Schroeder (backward integration) methods. In a further step, these methods are applied in some acoustic measurements employed in some opera houses in Italy.

“…The acoustical measurements were performed, in the first campaign of measurements in 2002, by positioning the sound source in 2 positions and the microphones in 54 positions between the stage and balcony, while in the second campaign in 2007, measurements are carried out by the sound source in 4 positions and the microphones in 66 positions between the stage and balcony. This could allow the opportunity to test innovative materials [24] and to build mathematical models to investigate deeply the acoustic phenomena [25] or simulation tool to check performance [26], even in historical buildings [27].…”

The Teatro Nuovo, the theatre where the famous international "Festival of the Two Worlds" is based, after a full restoration work and functional adaptation, has been returned to the city of Spoleto and its audience. The restoration works of the theatre started in 2003 for improving the safety levels and for adapting the operational functionality of the machines on the stage to the current needs of the show, including the acoustic performances. In particular, the Department of Energetic Engineering, Nuclear and Environmental Control of the University of Bologna collaborated with the Teatro Nuovo from the acoustic point of view, In order to monitor the acoustic performance of the concert hall, two campaigns of acoustic measurements, respectively before and after the restoration works, have been conducted, verifying the conservation of its original acoustical characteristics. The measurements were performed through an omnidirectional loudspeaker, a dummy head and a Soundfield probe. The results of the measurements of every campaign are presented in this article.

“…From this description, it emerges that no HVAC systems were conceived and, subsequently, modern high-tech solutions for thermal management do not fit for it [14] while, detailed analysis and tailored derived design should be done for handling carefully this existing building and preserving its architectural features [15]. Furthermore, it is noteworthy that so simple design is often discussed in the literature as the one performing in operation conditions most closely to its design ones, properly connecting those two phases [16].…”

Quick urbanization increment causes a few difficult problems, such as social assessment, more energy demands, and pollution increase. A positive factor for a city is the concentration of energy requests. On the other hand, urbanization trend is going to fragmentation of settlements, with a consequent expansion of the energy distribution networks but also an increase of the energy wasted. Each building needs some of the total energy distributed in the city. Energy needs can be grouped into four essential parameters: construction, heating, electricity, and water. How were these four parameters satisfied in the XIX century, before the industrial revolution? In those days' energy requirement wasn't so high and could be supplied with basic energy production technology. The knowledge of appropriate building technology (project), the use of (energy saving) materials, with a low and punctual heating system (fireplace, stove) or passive refreshment all intervened in this process. These requirements were achieved in each country using building plans studied to face different weather conditions with different architectural typology and with human effort and time (work-energy). This paper analyses an energy balance in a single typical building in the center of Italy, describing the energy flow that will show the logical and technical solution for "energy-saving". Old buildings (before the introduction of "building-plant") were always designed and built with an energy-saving concern. This article wants to propose the study of a typical building in which are used only low-energy systems to meet all the comfort requirements, to demonstrate that it is not necessary to use high-energy technology. This is how architecture urbanization studies and implementation can be used to reduce high-energy production needs.
