In many parts of the world, outdoor air quality is so poor that it is better to avoid ventilation with outdoor air. In such cases, the alternative is to substitute ventilation with air cleaning to maintain high indoor air quality. Even when outdoor air quality is good, the use of air cleaning substituting ventilation with outdoor air could reduce the rate of outside air supplied indoors and thereby energy for conditioning (heating/cooling) the ventilation air, filtration and for transporting the air (fan energy) can be saved.

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.
