Hi, I'm in the beginning stages of administrating my first WELL project. I'm trying to get my head wrapped around how to ensure that the preconditions are met through design specifications. I'm having a hard time quantifying how to go about ensuring some of the most basic preconditions are met, specifically Feature 01 Air Quality Standards. How does one go about defining that the standards for volatile substances and particular matter and inorganic gases are met? The other features, such as Feature 04 Part VOC Reduction and Feature 05 Air Filtration outline clear parameters for material selections or design strategies. But Feature 01 is so general that I'm unsure how you can be sure you'll meet it. Do you just gamble that simply following the other air filtration and material selection strategies will result in an outcome that meets this precondition and so you just wait and see? If not, how can a project administrator provide guidance on how to meet this feature?
