The impacts and management of outdoor-sourced PM2.5 in New Delhi's buildings : a simulation approach
… economic growth. As a large proportion of Indian buildings employ natural- or mixed-mode ventilation, and citizens in New Delhi spend up to 80% of their time indoors, the response of buildings to outdoor-sourced PM2.5 is a major, but relatively under-investigated concern. While much past work in …
