Hello,
I'm doing a C option PMV and I do not understand why I should build a post implementation model as it seems to be in UT3?
- I built a base line model,
- then the avoided energy use should be the difference between the base line model applied to the post implementation independant variable conditions minus the post implementation energy use.

What's the aim of the post implementation modelisation ?

Thanks for your feedback,
John.
