Hello! First, thank you Tristan for adding a WELL discussion to this site. I'm sure it will be a great resource for a whole host of "do gooders" like myself. :)

My question has to do with implementing WELL in a partially occupied building. We are engaged in a large LEED CS v3 project where approx 30% of the interior space is currently occupied by multiple tenants. The other 70% is undergoing a gut, phased renovation. The existing tenants may be relocated over time, but for now we are running under the assumption that their spaces will remain in tact with procedural changes and some mechanical system changes to accommodate all of the other changes to the building.

In the context of WELL, are there any "red flags" in a situation like this that we need to be mindful of? Particularly IAQ testing where the finishes were installed prior to any building modifications.

Thanks!
Brian
