Ashrae is there to give management cover for poorly=cheaply ventilated buildings. Some decades ago I worked in a Bell Canada data center which had Ashrae minimum air quality. I found another job. Employer owned buildings are vulnerable to ventilation penny pinching. Employee productivity does not enter the equation. Schools are also problematic, especially with more bodies/ft². With Covid, some parents equipped their kids with CO2 monitors. Some cash strapped boards tried to ban them. Commercial landlords with multiple tenants are less inclined to cheap out on ventilation if they want to retain tenants.
