Abstract: The health aspect is often overlooked in the assessment of ventilation systems on the market today as they focus on providing a comfortable indoor environment in an energy efficient manner. However, to what extent does achieving energy savings justify increasing the concentration levels of unhealthy pollutants? A new metric is introduced and discussed that quantifies the combined performance of energy saving and harm: The health-equivalent energy efficiency factor. Two approaches for the health-equivalent energy efficiency factor are evaluated and compared: the ‘fixed target approach’ and the ‘target reference approach’. These variations of the health-equivalent energy efficiency factor are calculated for eight smart ventilation strategies modelled using Modelica. One system is unable to provide energy efficient health-equivalent indoor air quality.
