WUFI

Does anyone have a tutorial or link to one that shows how to extract a psi value from a THERM model? Specifically I'm looking at a slab edge with a otential thermal bridge. I have a THERM model with data output, but no psi value to input into WUFI

Any help is appreciated.

Does anyone know how to accurately model a heat pump water heater that is ducted?

I'm hoping someone can help me. I'm very close to getting some output from my WUFI Passive file, but i get an error that reads: "...Visualized components/ Component 1: Subdivision horizontal, division 3, not valid data: Distance."

I'm at a loss as to what is causing this error. I've included a ...

So I'm trying to run one of those cool hygrothermic animatinos of a wall assembly in WUFI Plus mode. My calculation period is set for the month of February.

I think I've figured it out on my own. I'm going to use that basement space (zone 3) as an "Attached Zone" with a temperature reduction factor. Of course the reality is that this is not truly an "unheated, unconditioned space". And this feels like an inaccurate solution, so I'm still open to ...

I'm working on a retrofit project. I have 3 zones. Zones 1 and 2 are livable space with normal temperature settings and insulation. Zone 2 occupies half of the basement. It will be fully insulated and have normal temperature settings (68-77 degrees F). Zone 3 is the other half of the existing ...
