The health, academic performance, and general well-being of pupils and staff are negatively impacted by poor indoor air quality (IAQ) in schools. Breathing problems, allergies, and asthma have been related to poor indoor air quality (IAQ). By eliminating contaminants and allowing for sufficient air exchange, ventilation systems play a critical role in keeping indoor air quality in schools at a healthy level. However, the energy needs of these systems may increase school operating expenses and could have an adverse effect on the environment. Variables including system type, building characteristics, occupancy, and temperature affect the energy consumptions for ventilation use. Natural ventilation, mechanical ventilation, and hybrid ventilation systems have all been the subject of recent research into their effects on indoor air quality and student comfort in the classroom. By comparing the efficacy of four distinct decentralized ventilation systems, this research hopes to add to the knowledge of IAQ and energy consumption in educational institutions. Heat recovery ventilation and demand-controlled ventilation are tested, along with their effects on indoor air quality, thermal comfort, and energy consumption. This research will enhance IAQ by shedding light on how to design and operate ventilation systems in educational institutions, while decreasing energy use and expenditures.
