Improving indoor air quality and occupant health through smart control of windows and portable air purifiers in residential buildings

Indoor exposure to PM 2.5 (particulate matter with aerodynamic diameter less than μm) has a substantial negative impact on people’s health. However, indoor can be controlled through effective ventilation and filtration. This study aimed develop smart control framework that (1) combines portable home air purifier (HAP) window system reduce concentrations whilst maintaining thermal comfort; (2) evaluates the associated health impacts additional energy use. The proposed was demonstrated simulation-based case of low-energy apartment. simulation results showed joint HAP openings great potential not only maintain comfort but also achieve removal which, consequently, lead considerable benefits at low cost. Compared similar previous studies, strength lies in combining operations HAPs same including both as targets. work introduces novel concept linking building assessment, an important innovative step creation holistic responsive controls. Practical application: proposes jointly controls purifiers (HAPs) windows removal. suggest such hybrid strategy result costs.
