Energy-saving benefits

This manuscript discusses the energy-saving benefits of gas-phase air cleaning in Nordic buildings. Ventilation systems are crucial in creating a healthy and comfortable indoor environment. These systems account for around 30% of building heat losses in cold climate regions. Indoor emissions from materials, occupants, and outdoor pollutants are key to ensuring acceptable indoor air quality levels. Therefore, this study focuses on using gas-phase air cleaning technologies in low-energy centralized air handling units.
