Health and safety is about short and long term effects. There is a debate on how CO2 affects our health. But there seems to be a consensus that levels above 2000ppm disturbs our wellbeing and efficiency, levels above 5000ppm are starting to become hazardous and 10000ppm is life threatening. The latest research that we know of is conducted at NASA. There has been a rigorous health control on the astronauts working in the International Space Station (ISS). As they have started to see symptoms related to high CO2 levels a clinical study* has been initiated here on earth. In our own tests a human in a confined space of about 2m3 will raise the level of CO2 to 2-3000ppm within 3 minutes. Does it affect you? Try this in our booth the next exhibition you visit.
Please look into Knowledge where we will link to publications on the effects.
IoT and sensors
Most associate IOT with home and office automation. In the world of HVAC this development has been going on for at least 20 years. From our perspective IoT has made the invisible visible and connected systems to the cloud. In a controlled biotope the air has to be safe and fresh. As awareness is rising with visible technology, sensors become our 7th senses. A major property owner in commercial buildings believe that we soon will have a sensor in every ½ m2 (not necessarily CO2 sensors everywhere).
Believe it or not, but after a major investment is made in a sophisticated ventilation system most owners fail** to keep up with minimum standards of air quality. This in turn will create a demand from occupants to be able to control their environment or at least to get adequate measurements for an authoritative discussion.
