Sign #9 – Indoor Environmental Quality - Take a deep breath. That air you’re breathing
has gone through how many filtration systems to ensure it is safe and healthy? (Okay,
take another breath.)
The Physical Sciences (PS) building features mechanical and passive ventilation systems
that seek to ensure that adequate fresh air is available for occupants in the building.
All occupied spaces in the building have a minimum of 3 air changes per hour with
some heavily-occupied spaces having as many as 10 air changes per hour.
What does this mean? Well, basically, it means that fresh air is continually being
pumped into the PS building for all occupants—regardless of the location of the building.
Fresh air contributes to minimizing the effect of carbon dioxide that can build up
inside closed spaces. Because carbon dioxide is colorless and odorless, filtration
and ventilation systems must focus on minimizing its presence from within the building.
