How to Improve Ventilation?
Ventilation has become a concern for most buildings due to primary reason of high probability of cross infection through air. Ventilation can be determined by checking the CO2 levels in the indoor air. High CO2 Level >800 ppm, means relatively less fresh air is introduced in occupied space based on the occupancy rate. Less fresh air means less dilution and high recirculation of stale air. Which essentially means, the air being exhaled carrying aerosols will remain in the air for longer time with chance of cross breathing and thus cross infection.
NEA together with BCA made new recommendations and suggested measures which can be found on the NEA / BCA website.
We recommend to use Hygiene Controller which can monitor the indoor air quality and also provides control mechanism for ventilation modules like FAF, ExF, Air Purifiers, dehumidifiers etc…
Its intelligent module can also send messages with alerts.
Control strategy can be based on the parameter readings in the room so the maintenance team can control the IAQ inside the room.
Smart controller allows you to..
- Avoid too much humidity build up in the indoor environment.
- Control ventilation and introduce fresh air in the occupied space.
- Ensure particulate matter is controlled.
- Smart scheduling and condition based control ensure devices don’t run 24×7 and waste energy.
Did you know ?
- Ideal Co2 range should be 450 to 700 ppm. However in many offices the levels were found above 850ppm with alarming levels going >1200ppm.
- At Hotel Guest rooms, or home bedrooms the levels were recorded >900 up to 1800ppm
- Humidity >70% encourage mold growth.
- PM2.5 levels beyond 50ppm indicates unhealthy range.
