The indoor air quality of airconditioned offices is a subject of public health importance because we spend a substantial amount of time in these premises. Good indoor air quality can lead to improved productivity at the workplace. On the other hand, poor indoor air quality will cause
Carbon dioxide, CO2, is composed of 1 carbon and 2 oxygen atoms. It is a colorless, odorless, and nontoxic gas in its normal condition. Carbon dioxide is not a harmful air contaminant, but we often use it as an indicator of indoor air quality. Put it simple, we breathe in oxygen and release carbon dioxide.
Jan 29, 2020· Please Don''t Blame ASHRAE Standard for 1000 ppm CO2. February 9, 2021. Author(s) Andrew Persily. Software. CONTAM. January 8, 2021. CONTAM is a multizone indoor air quality and ventilation analysis computer program designed to help you determine: (a) airflows: infiltration, exfiltration, and.
