[Greenbuilding] Stale Air

[John Bone]

Yes, You are indeed correct I did mean to Type CO2 (Carbon Dioxide),...  
and you are right to the expert air-conditioning and ventilation (fresh  
air) are different thinks. But alas to many lay (ordinary folk) persons  
they think an air-conditioner unit will replace the used up oxygen and  
remove the human or combustion produced CO2 from aroom that is otherwise  
"sealed". In 35 year of being a building control officer (building code  
official) this myth is still as dangerous as ever, even with some  
proffessional clients. "Why do we neeed the opening windows when we ahce  
these air-con units...??""
