Missing input options

[curiotrope]

Hi! I have been using BEopt xml files as a starting point for running models in OCHRE. I came across some options in BEopt that cause errors in OCHRE. I assume this means that OCHRE is missing these options as possible inputs.

These missing options were

1. Foundations/Floors>Crawlspace = 4) Wall R-10 XPS, Unvented

2. Foundations/Floors>Crawlspace = Wall R-12 Polyiso, Unvented

3. Airflow>Ventilation = 4) CFIS

I'll note that the options that did work for OCHRE were Crawlspace = 19) Ceiling R-19 Fiberglass Batt, Vented and Mechanical Ventilation = 3) Supply. I ended up making these adjustments, and then my models ran just fine.

Hope that helps!

@curiotrope: Sorry, I've owed you a fix here for a while! Here's an update at the least: We're planning to do a new release later this week, and I'm trying to have it cover as many insulation options that are in BEopt and not OCHRE right now as possible. I'll make sure these ones get priority, and then try to cover as many other cases as time permits.

CFIS is a more complicated one to cover, and I'm not sure that we'll be able to do that for the next release. Adding insulation options is basically just adding new rows in a table, whereas support for CFIS involves some more detailed changes in the code and a lot of testing (for insulation so long as the table's right we just need to make sure it pulls the new values correctly). I can make that into a separate issue, but I'm not sure how quickly we'll be able to get to that one, as right now we don't have a lot of time we can use for adding new features and I don't know of any other projects that need this capability to help cover the costs.

Just a quick update for you @curiotrope: We've realized that there's actually an issue related to insulated foundations adjacent to garages related to BEopt (BEopt assumes the area adjacent to the garage foundation is uninsulated, and the rest of the wall has the specified insulation), and that the issue isn't just with missing options (R10 crawlspace walls are supported, R12 are not).

We're hoping to have a fix for you later this week, but I need to have some discussions and think about how we'll handle this in OCHRE. Sorry for the delay, hopefully we'll get something figured out later this week on this.

@jmaguire1 can we close this?
