STRATEGIE DI RENDIMENTO ENERGETICO DEGLI EDIFICI SCOLASTICI. IL LICEO CLASSICO DANTE DI FIRENZE

Energy refurbishment solutions, dedicated to historical buildings, especially if these last belong to Cultural Heritage can be assessed by using effective simulation tools, often based on CFD techniques. This work proposes a simple method useful to identify efficient energy saving solutions conceived as tools for the protection and requalification of the building-plant system. The Classic and Musical high school Dante Alighieri of Florence is the case study. We propose a method based on dynamic simulations that allows plant designing oriented to the effectiveness and guarantee of the correct ventilation, energy efficiency but at the same time reversibility and movability, easy management and maintenance. Transient simulations of building-plant system are oriented to dynamic control of the plant system, to the adaptive and proportional regulation, in such a way as to ensure that the plant adapts to thermo-physics and thermo-hygrometry of building and indoor environments. Results showed that plant system refurbishment and building retrofitting solutions are more efficient when connected to integrated controls, identified by means of dynamic thermophysical and energy performance analysis and validated with in-depth comparison of energy saving and environmental impact produced effects. Expected results confirm the achievement of occupants wellbeing, better thermo-hygrometric conditions, correct air change ventilation and indoor air quality.
