Clean Air Standards and Advanced Technologies

Pre, during and post CV19 there have been multiple recommendations, guidelines and standards introduced to our industry. While each of these initiatives by themselves make good sense and have added real value, many also overlap, so what do we recommend as an industry to the end user, consulting engineers, contractors and to our own internal teams on what we recommend and why?
This is a very complex topic and I do not expect to deliver the ‘magic answer’ but the subject should be tabled for continued discussion as we develop a more coherent direction for the competing recommendations and ultimately deliver what we all want, i.e. to manufacture, supply, install and measure the optimized solutions for clean, conditioned indoor environments that meet our collective sustainability goals.
