Abstract

Evidence for the impact on health of interventions that improve the indoor environment can take years or even decades to be identified and actionable. However, health impact modelling can be used to estimate changes in rates of morbidity and mortality due to changes to the environment, which can be simulated using physics-based models. In the past, these tools have not been used in combination to assist in real-time building controls. The work described here builds upon previous work that proposed a smart control framework that combined portable air purifiers and automatic window control systems to reduce indoor PM2.5 concentrations in residences whilst maintaining thermal comfort. The modelled changes can inform health models for better estimations of the impacts to population health due to the implementation of controls that use both thermal conditions and contaminant concentrations as control targets. The IAQ modelling, which uses EnergyPlus to simulate both indoor contaminants and thermal conditions, includes different ambient pollution levels, and, importantly, different occupant behaviour profiles (e.g., cigarette smoking). The approach to quantitative health impact assessment in this work is through life-table models that predict survival patterns based on age-specific mortality figures and hazard ratios. The simulation results showed that dual control of portable home air purifiers and window openings has the potential to not only maintain thermal comfort but also achieve effective PM2.5 removal even in cases of high indoor sources which, consequently, can lead to considerable health benefits at a relatively low energy cost.
