Abstract: It is possible to use gas-phase air cleaning to improve the indoor air quality and reduce the energy use for ventilation. However, the energy implications of gasphase air cleaners and the impact on the air quality are not yet quantified. Therefore, by using a dynamic building simulation, the impact of different clean air delivery rates on the energy use and indoor air quality were studied under different climatic conditions. The results show that air cleaners can reduce the energy use for conditioning and transporting the ventilation air by 1.9% to 18% while possibly reducing the pollution level of buildings. The amount of energy saved is however dependent on the boundary conditions of the system.
