NC-v4 EAp1: Fundamental commissioning and verification
The Pre-req Cx and Enhanced Cx in V4 both mention "durability" in the intent paragraph (along with the ones most of us are used to... energy, water, IAQ). In all of my experience on LEED projects and as the CxA on projects, I have yet to address this directly, or have a reviewer ask about it. I am curious how others interpret this, and what others think a Cx team's should address durability (perhaps some examples).
Thank you

For a building with individual systems per unit, does every single system need to be commissioned?
What kinds of projects must the CxA demonstrate experience on?
What level of authority does the CxA have towards correcting inaccurate or erroneous construction?
Can the CxA be a member of the design or construction team?

Very good question! I think that including durability is an initial nod to resiliency. Recently, I have been thinking about resiliency a lot and it opens another path and justification to sustainability. As with anything, it is up to the reviewer what that means. The durability of a furnace unit is substantially different than an air handling unit, a mag-lev chiller versus conventional, central equipment versus distributed. All have a service life and different durability. Considering this in the selection of a system might even be called life cycle cost analysis! Things to think about...
