Indoor air quality (IAQ) plays a vital role in supporting both the physical and mental well-being of individuals enclosed spaces, mechanical ventilation systems has gained increasing attention due to building design’s focus on energy efficiency thus airtight constructions. This study investigated pre–post effects installing heat recovery system (MVHR) indoor high school classroom Ferrara, Italy. The analysis focused experimental measurements temperature (T), relative humidity (RH), carbon dioxide (CO2) inside outside same classroom, which had constant occupancy (17 students) for an entire year, allowing comparison between natural ventilation. With comprehensive approach, particulate matter (PM2.5), volatile organic compounds (VOCs), radon levels (Rn) were monitored as well, after installation MVHR. By comparing ventilation, highlights strengths limitations implemented, together with evaluation system’s consumption, including 2 kW post-heating battery. In terms results, MVHR demonstrated clear benefits managing CO2 improving sensory, olfactory, psychophysical well-being, well students. detail, under peak concentrations exceeded 4500 ppm, while kept them below 1500 ppm. average concentration during dropped from 2500 ppm around 1000 achieving 62% reduction. However, beneficial not observed other parameters, such PM2.5, VOCs, or radon. latter displayed annual values 21 Bq/m3 peaks reaching 56 Bq/m3.
