Modelling consortium for chemistry of indoor environments (MOCCIE): integrating chemical processes from molecular to room scales

We report on the development of a modelling consortium for chemistry in indoor environments that connects models over a range of spatial and temporal scales, from molecular to room scales and from sub-nanosecond to days, respectively.

Emerging investigator series: primary emissions, ozone reactivity, and byproduct emissions from building insulation materials

Insulation materials affect indoor air by (i) releasing primary volatile organic compounds (VOCs) from enclosure cavities to the interior space, (ii) mitigating exposure to outdoor pollutants through reactive deposition (of oxidants, e.g., ozone) or filtration in infiltration air, and (iii) generating secondary VOCs and gas-phase byproducts from chemical reactions.
