NC-2009 IEQp1:Minimum IAQ Performance

Existing building with new addition compliance

we have a new addition added to an existing facility. The consultant has decided to pursuit NC for this project, therefore the question comes if there is an existing area within the LEED boundary with existing AC units that wont be modified, do these units need to comply with the minimum OA required as well? Would a Test and Balance be necessary or only plans? In the case that they take these existing areas out of the LEED boundary, only the new equipment will need to be Tested and Balanced, correct?

i.First of all, there are two different concepts here: this prerequisite requires your project to have VENTILATION (natural, mechanical, engineered...) regardless of whether or not you have A/C. ii.Every occupiable space within your LEED Project Boundary must be ventilated. I am pretty sure your reviewers will require you to demonstrate that. iii.Regarding your cx question I would ask in the EAp1 forum.
