Hello,

I am wondering if anyone has links to residential (single family and/or small residential 'triple-decker') prototype models, analogous to the US DOE 90.1 prototype models? I am looking for prototype models that are minimally code compliant in Massachusetts.

I found the following link to some IECC residential models, but it seems that the most recent edition is 2012 IECC models. https://www.energycodes.gov/developme...

Are there any 2015 IECC models, or a resource that shows the main difference between the 2012 and 2015 IECC?

Thanks so much! Ryan

As a follow up. Have you had any success migrating those past models from their energy plus V5 to something more recent?

The link you mentioned is the best for code compliant prototype models.

There is very little difference in performance between IECC Residential 2012 and IECC Residential 2015. Mainly, 2015 requires blower door testing (though the ACH50 requirements are the same). 2015 also adds a fifth compliance path using the Energy Rating Index (ERI) aka HERS Index.
