Ventilazione, condizioni di benessere e qualità dell’aria all’interno di un edificio di pregio storico-artistico. Il Teatro Niccolini di Firenze

In the present research the effectiveness of air fluxing scheme in a public and particular environment belonging to the Cultural Heritage in Florence, was investigated: the new Niccolini Theater. The microclimatic and microbiological control are fundamental to guarantee health, safety and well-being of people, and also effective, when achieved with plant solutions that allow good conditions of indoor air quality (IAQ, Indoor Air Quality), thermo hygrometric well-being and also significant energy savings . The building-plant system analysis, aimed at evaluating the microclimatic conditions that guarantee thermo hygrometric well-being and IAQ requirements within a historical theater is the aim of this work. Through dynamic simulation and CFD (Computational Fluid Dynamics) application, it was possible to evaluate the efficiency and effectiveness of the HVAC system, taking into account the building's thermal physics and the time profiles of use related to occupancy levels . From the obtained results it was possible to infer that the effective distribution of air in the environment not only ensures thermo hygrometric well-being to the people / spectators, but it is also a guarantee of hygiene and indoor air quality. This is a very complex issue when plant systems (HVAC; Heating Ventilation and Air Conditioning) for public entertainment environments must be built inside historic buildings belonging to the Cultural Heritage and therefore subjected to the Superintendence restrictions, both from the architectural and plant system point of view, such as the Niccolini Theater, which constitutes the case study.
