I did create a very basic single room model which as you say takes some setting up, although I assume things would speed up with experience. What concerned me was the output on first attempt didn't convey much reassurance as to the content but to be fair it was just a couple of hours messing. What I need is confidence that if I put the time in, will I see any benefit or should I just say to my associate "Here's a set of element / part schedules, you work it out!".
As you say, hopefully someone else has already been down this road that can share their experiences of meeting Passivhaus standards?
