Steam that was the "standard" or "rule of thumb" before we had 62.1. and the code requirement for ventilation. There is no "10%" standard anymore. The IMC 2006 calls for different ventilation rates based on the type of building and rooms such as restrooms, classrooms, office areas, etc.

We don't have that code yet in GA but will have it Jan 1, 2014. Don't know to much about that yet other that in some cases you are allowed to have less OA than in the IMC 2006. Thank you very much

My aim is not to pass laws, but to repeal them. It is not to inaugurate new programs, but to cancel old ones that do violence to the Constitution."
