Hello everyone - Our project's registration details reference building square footage as 51,441. However, we've only finished 40,100 sqft. Given that our registration makes reference to the 51,441 value, will our flush calculations be driven by actual finished area or total building area? I ask the question because our mechanical sub submitted his calcs based on finished space?
thanks-
tom

Thomas,
We've come across the same question on our projects as well. The LEED manual did not seem to provide a definitive answer so we have gone with the project registration square footage to be on the safe side.
In your case, there is a significant difference in sqft and it would probably be worth it to flush out less sqft while providing the LEED reviewer with an explanation/justification.
Consider reviewing what sqft is being ventilated by your HVAC systems. If the unfinished area is not ventilated than you don't have an opportunity to flush it out anyway.
