In many discussions online, the topic of monitoring Carbon Dioxide (CO2) in indoor spaces has become prominent. At CETEC, where I work, we routinely engage in this practice. In this post, I aim to shed light on why measuring CO2 levels is crucial, what it reveals, and the associated limitations.
What is Carbon Dioxide? Carbon Dioxide (CO2) is often used within the indoor environment as a way to determine the ventilation rate. When an indoor environment is unoccupied and there is air entering from outside the concentration of carbon dioxide will eventually reach the same as the outdoor levels. When people enter the space, as a result of breathing they produce carbon dioxide (amongst other things) and over time the concentrations increase . Whilst many buildings are designed to have specific […]
What is Particulate Matter? Particulate Matter, also known as PM or Particle Pollution refers to extremly small solid particles and liquid droplets which are typically suspended in air. Particulate matter can be made up of a variety of compounds from soil or dust particles through to organic chemicals, metals and other compounds. The size of the particulate matter can have a significant impact on its potential to cause health problems, and this is often how it is graded; PM10 refers […]
I work for a company called CETEC who work in the Built Environment and do a lot of work around how people can improve their Indoor Environmental Quality (IEQ) to obtain the maximium amount of labour productivity within service related industries. This is an area where there is little knowledge over the importance of IEQ, and over the next few months I will be doing some posts to highlight what contributes towards IEQ and subsequently occupant productivity. These posts are not […]
