Ventilation & CO2 Levels

The airborne nature of Sars-Cov-2 has highlighted the need for good ventilation within indoor spaces. Good ventilation lessens the concentration of airborne viral droplets by preventing their build-up as infected occupants respire. CO2 levels can be used as a proxy for the quality of ventilation of the space. As occupants respire CO2 is expelled and will also build up if the space is not well ventilated. Outdoor air (“fresh air”) has approximately 410 ppm of CO2.

Please note that CO2 levels in an indoor space is an indicator of ventilation quality but not of air quality as other pollutants exist such as particulate matter and gasses such as nitrogen dioxide which have no correlation with the level of CO2.

Our BMS free CovidControl solution utilises a LoraWan CO2 sensor that will wirelessly communicate back to a local or public gateway also known as a hotspot. Don’t worry the data is encrypted. The sensors are battery-powered and require little to no additional infrastructure and as such are quick to set up and install. This enables many rooms to be outfitted in a day by simply affixing the sensor to the wall which can be done with double-sided industrial velcro, glue or more traditionally simply screwed in place.

Each sensor is assigned to a space and fitted with an identifying QR code (linking the sensor to the space).

The sensor will send the data back to our Digital Building Platform via the Helium network. Future Decisions has purchased a private OUI on the helium network so you can be sure your data is routed only via us and is totally secure. The security of the network is backed by the Helium Blockchain.

When you enter a space

When an occupant enters a room they can simply scan the QR code on the sensor using the CovidControl App.

Scanning the sensor provides access to the rooms ventilation data displaying the space's temperature, humidity and CO2 level (ventilation).

The interpretation of the data is colour coded for ease of use and configurable in the platform.


Room Status

The app will provide a colour coded interpretation of the data. A ventilation warning results if levels of CO2 are too high due to insufficient ventilation of the space.

In buildings or spaces with no BMS system operating then opening windows or doors is advised to bring CO2 levels down to maintain a lower infection risk.
