Hello!
I just bought a one and a half-story house with a basement and a poured concrete vault built in 1971. It has never been renovated since. Almost fifty years with only one maintenance, taking out the wood furnace to the outhouse with an accumulator tank and installing an air/water heat pump (I believe this was done around -12/13).
The upper floor is a finished cold attic with a loft hatch. The plan is to remove the loft hatch and place the hatch on the facade instead. The entire upper floor has crawl spaces. The ventilation is, of course, natural draft. My idea for the whole house is to add insulation to the roof, facade, and basement walls and install an HRV system. The HRV system will probably be placed in the boiler room in the basement or up in the crawl space. Perhaps the boiler room is the best option if condensation occurs? Then I wonder if you can combine an exhaust air heat pump with HRV? Or is it an expensive uneconomical story.
But first and foremost, I will start with the roof and work my way down. Considering the previous owner thought it was good to have the exhaust on the cold/crawl attic from the laundry room in the basement... So there's been a bit of moisture leakage, so to speak, with black mold here and there but no white mold, fortunately.
I have discussed the approach with my father. We are a bit confused about how and if we should install a vapor barrier. And if so, whether to run a vapor barrier along with the roof truss and out to the existing facade and then let it go down to the basement wall. Or if we should run it along with the roof truss and then along the inside. Or along with the roof truss down by the crawl space and continue to the eave and down. Does it matter if the crawl space is heated or not? It should be noted that the interior will be renovated after the exterior is finished. Or to lay plastic on the sheathing and down all the way to the basement wall and "encapsulate" everything.
Or alternative solutions with open membranes, which I haven't researched much.
The goal is to reduce energy consumption, and it should last.
Had lively discussions about which choice is best So that's why I'm asking here.
What do you think? The house needs renovation. Windows need to be replaced, the roof needs to be redone. The facade needs replacing. The basement needs to be examined and fix cracks, moisture barrier, and drainage needs to be done. And stormwater pipes need to be laid.
If anything needs to be added in terms of information, let me know. I can try to get pictures if needed. But not guaranteed as I can't enter until June 29.
Otherwise, feel free to say which approach is the best choice according to you. Maybe there are other options I've not thought of?
Best regards, Daniel
PS. Not sure if it's in the right part of the forum.

Regarding ftx and exhaust air heat pump, I have sent the question to NIBE and am awaiting a response.
But is there anyone here who has any tips or ideas on how to proceed?
Heard from someone who was renovating his entire house from ~65. He put plastic on the walls from the base to the eaves and from the eaves he installed a diffusion-open membrane? He was a bit unsure because it was the carpenter who arranged everything.
