Yeah.

Uh, well, m- maybe, you know, a, a open building w- with no A- AC, you know, j- just a container, but outside of that, uh, it's, it's your largest load.

So, and our goal for commissioning is how to make that HVAC more efficient so you can save energy.

So that's really what it's all about is, uh, like I said, I, I'm a, unfortunately, you know, I know we're in a mechanical engineering podcast, but I, full disclosure, I'm a g- I'm a, you know, graduated electrical engineer.

Right

... we're looking at the system, their BAS, and, and testing through there, and then doing some f- uh, field verification.

So controls is extremely important.

But, uh, CFD modeling, like we were just talking actually on a call maybe about an hour ago, hour ago after, after my call with Will, uh, we're doing a retro commissioning proces- project, and we're actually looking at understanding, uh, that design that might have been done 10 years ago, does it match now? So let's-
