TL;DR: It is argued that existing evidence is sufficiently strong to warrant engineering controls targeting airborne transmission as part of an overall strategy to limit infection risk indoors, and that the use of engineering controls in public buildings would be an additional important measure globally to reduce the likelihood of transmission.

TL;DR: Surprisingly, a comparison of the maximum exit velocities of sneezing reported here with those obtained from coughing (published previously) demonstrated that they are relatively similar, and not extremely high, in contrast with some earlier estimates of sneeze Velocities.

TL;DR: The ASHRAE Global Thermal Comfort Database II (Comfort Database II) as discussed by the authors is an open-source thermal comfort database that includes approximately 81,846 complete sets of objective indoor climatic observations with accompanying subjective evaluations by the building occupants who were exposed to them.

TL;DR: In this article, a reflective approach is adopted in analyzing the reviews on the impact of indoor air quality on humans over the last 30 years (1986-2016) and the major findings reiterate the concerns of indoor pollution (IAP) and provide a deeper understanding of how contaminants contribute to, and interact to accentuate the adverse effects on humans.

TL;DR: In this paper, a field survey was conducted to evaluate thermal comfort perception of the occupants in naturally ventilated public housing in Singapore, and thermal acceptability assessment was performed to find out whether the indoor environment meets the ASHRAE Standard-55's 80% acceptability criteria.
