· Regular and correct ventilation is important during the coronavirus pandemic. While this isn't a problem when it's hot outside, on cold days it's important to ensure that rooms do not get too cold ...
· However, it isn’t known if the usual winter set point for CO2 is appropriate in a Covid-19 pandemic. Where an existing HVAC system is recirculating air containing small clusters of SARS-CoV-2 virus, the risks of air-recirculation need to be quantified. In the meantime, REHVA advises avoiding central air-recirculation during Covid-19 episodes and closing the recirculation dampers, even if ...
Even with other controls in place (including; social distancing, frequent hand washing, increased cleaning regimes, use of face coverings/transparent barriers/shields etc.), employers should still consider the risk from airborne transmission of the Covid-19 virus from aerosols in poorly ventilated indoor spaces, particularly if individuals are in the same room together for an extended period ...
· This hierarchy places elimination (physically removing the pathogen) at the top of a priority list, followed by engineering controls (separating people from the pathogen), administrative controls (telling people what to do), and personal protective equipment. Ventilation controls – such as CO 2 gas sensors – are a type of engineering control. They separate people from the pathogen by ensuring …
When used correctly, they cover the nose and mouth, which are the main sources of transmitting coronavirus (Covid-19), confining/containing droplets and larger particles and helping prevent them from entering the general environment. There are some circumstances when wearing a face covering is required as a precautionary measure. You can find out when workers need to wear a face covering on …

· Einfache CO2-Sensoren können helfen abzuschätzen, wie verbraucht die Luft in Innenräumen ist. Durch gezieltes Lüften ließen sich so womöglich Sars-CoV-2-Fälle verhindern.
· The coronavirus crisis has prompted calls for a greater focus on infection control in the design of public toilets, including much greater use of sensor taps.
to disable demand-controlled ventilation (DCV).2 DCV is a common energy-saving control strategy that reduces outdoor airflow during periods of partial occupancy, typically using a carbon dioxide (CO2) sensor, an occupancy sensor, or some other means of counting people. Disabling DCV will …
· Every time you exhale, you release CO2 into the air. Since the coronavirus is most often spread by breathing, coughing or talking, you can use CO2 levels to see if the room is filling up with ...
· "CO2 sensors have been around for a long time, but the difference is that they had not previously been considered to confront coronavirus contagion," Finger said.

Designers assume that controlling CO2 controls all occupancy-related pollutants. CO2 sensors are relatively precise, reliable, and inexpensive compared to other types of DCV pollutant sensors. Occupancy sensors count occupants and regulate ventilation airflow accordingly. A major purpose of ventilation systems is to control relative humidity. Relative humidity (Rh) compares air’s water vapor …
