[Equest-users] LEED Increased Ventilation ASHRAE 62.1

[Paul Diglio]

Per the LEED NC V3  requirements in order to qualify for IEQc2 the ventilation 
in the  breathing zone needs to be increased by 30%.

62.1-2007  defines the breathing zone as "the region within an occupied space  
between planes 3 and 72" above the floor and more than 2' from the walls  or 
fixed air-conditioning equipment."

I do not understand what is meant by "planes 3".  

Can anyone shed some light on this?  Has anyone has success modeling a reduced 
space volume in eQuest or is it easier to perform a manual calculation and 
adjust the CFM of outside air per a weighted volume? 


Thank you,

Paul Diglio
