Evaluation of UVC Light for Disinfection in Hospital

The UV-light disinfection system must operate in UNOCCUPIED rooms. No touch UV technology is dependent on the distance between the lamp and the surface being disinfected. The inverse square law applies.

Building Design Strategies in the Fight Against COVID-19

Many of the evidence-based strategies within WELL v2, spanning building design and operations, as well as company policies and culture, are providing an actionable framework for organizations and communities responding to COVID-19 and preparing for a safer and healthier future.

Environmental Contamination in Virus Transmission

Beyond catching the infection through coughing, environmental contamination was an important factor in the disease’s transmission. Environmental contamination by patients with Sars-CoV-2 through respiratory droplets and fecal shedding suggests the environment as a potential medium of transmission.

Airborne Disinfection by Hydrogen Peroxide

Hydrogen peroxide is active against a wide range of microorganisms. Hydrogen peroxide can be corrosive to the eyes, skin, and respiratory system. Inhalation of vapors, mists, or aerosols from concentrated solutions of hydrogen peroxide can cause significant morbidity.

Particulate Matter Pollution and COVID-19 Infection Relationship in Italy

In conclusion, the rapid COVID-19 infection spread observed in selected regions of Northern Italy is supposed be related to PM10 pollution due to airborne particles able to serve as carrier of pathogens.

Air Quality in Schools & Children’s Exposure to Particulate Pollution

Children in schools constitute a particularly vulnerable population group to indoor air quality, because of their physiological and behavioural characteristics. They have higher ventilation rates and higher levels of physical activity with the result that they receive much higher doses of air pollutants than adults.

Air Quality Investigation at Schools in Hong Kong

Indoor CO2 concentrations exceeded the ASHRAE standard due to overcrowded classrooms and inadequate ventilation. Implementation of more breaks and recesses between classes might alleviate the high level of CO2. The occupancy of classrooms in Hong Kong often exceeded the maximum occupancy of the ASHRAE 62-1989 standard. Decreasing the number of students in each classroom can also lower the CO2 level. Increase the rate of ventilation could remove the accumulated CO2; for example, the use of ceiling fans, exhaust fans could increase the exchange of indoor air with the outdoor.

Project BioSUB – Live Underwater with a coiled Algal Oxygen Bar

Australian marine biologist Lloyd Godson lived for two weeks inside the world’s first self-sufficient, self-sustaining underwater habitat BioSUB. He breathed air from microalgae that gave off oxygen through a gas-exchange Biocoil, watered with recycled urine.
