“…Noro and Zilio [23] in a previous study compared different systems (sensible or total heat recovery, heat pump, heat pump coupled to a recuperator) by dynamic simulation, demonstrating that they allow significant non-renewable primary energy savings. Energy analysis highlighted that thermodynamic heat recovery, that is, coupled use of sensible or total heat recovery and reversible heat pump, is the most advantageous configuration for school ventilation both in colder and humid climates like Milan and in milder climates like Palermo, even more when increasing ventilation flow rate (as desirable in the COVID-19 pandemic) and for new or retrofitted buildings.…”

Since the first COVID outbreak in 2020, schools have been considered a substantial issue with regard to the spread of the disease, as they represent indoor environments that are continuously occupied most of the time. Several studies have underscored the crucial role of mechanical ventilation systems in the fight against any pandemic caused by airborne pathogens. AiCARR, through its associated companies, donated a mechanical ventilation system to a public school in Rho, Milan province (IT). The primary objective of the installation was to enhance safety by diluting indoor contaminants, improving indoor air quality, and ensuring thermal comfort. During the course of the project, the focus included advancing energy efficiency and reducing operational and maintenance costs. This article presents the first year operational data recorded by the monitoring system that include outdoor and indoor air temperature, relative humidity, CO2 concentration and unit electric consumption.
