Northern Michigan un vented, un air conditioned Cabin roof design

Northern Michigan un vented, un air conditioned Cabin roof design.
After reading several articles, opinions and Blogs I have a better understanding of the moisture vapors that exist and the problems they can create in walls and especially the roof. But I’m a little unsure of the proper design and construction for my great lakes, shore line cabin roof design. I have detailed my current plan below. Could please you give input as to where my design plan is OK or deficient in proper vapor management for this environment and situation.

Should I install a vapor barrier under a LVT (Luxury Vinyl Tile) flooring material?

Existing home has an inordinate amount of moisture/water under the raised wood floor (two-story SFD structure).

Realizing that the moisture should be mitigated by possibly at least installing an impermeable moisture barrier at dirt, I am wondering (assuming owners do not elect to install mitigation in crawl space) if the floor assembly should be as follows?

Existing Plywood Subfloor
Vapor Barrier (6 mil poly)
Plywood Underlayment
Floating Click system LVT

What to do with torrents off the roof?

Zone 4A, East TN, annual rainfall >50" and downpours can be significant. Upslope lot.

Downspouts will tie into 4" pipe to daylight, but then what? Seems responsible to NOT discharge it down the driveway. But if I discharge it onto the slope it would soon create a local grand canyon.

There will be a 3' garden wall to provide a level grade in front of the house. The 4"gutter drains will exit through that wall in two or three places.

Any tried and true remedies?

Mitsubishi minisplit 8-head system is not keeping up

Back in mid-November 2016, we had a Mitsubishi Hyper Heat MINI Split installed in our house after opening up the first floor of our home and installing some beams to make it more open. We lost duct work feeding the second floor, and had to come up with a solution. We decided on a Mitsubishi ductless system, since I had a smaller version installed in our detached garage and was very happy with it. My uncle did the garage, while I went with one of the Mitsubishi Diamond Dealers to handle our house. After 3 quotes, we decided on a company and proceeded.

Intus Eforte mounting brackets

Question for anyone with experience installing Intus Eforte windows: The brackets I received with my Intus windows seem too wide. There should be a pic attached showing a bracket sitting in front of the track it is supposed to twist into. Online images depict a different type of bracket. All mounting instructions depict brackets with teeth that are only slightly wider than the mounting track. Did I get a batch that belongs with a different window type or something?

Thanks for any help.

Vapor barrier inside double stud wall — is this OK?

I’m building an energy efficient house this spring 25 miles Northwest of Minneapolis in the upper portion of zone 6. My wall design plan since the ’80s has been a double 2x4 stud with the vapor/air barrier in the gap between the two walls. This is similar to Joe Lstiburek's Ideal Double-Stud Wall Design with 2 taped layers of 1.5” Foil Faced Polyisocyanurate foam board replacing the ½” OSB in Joe’s design. I believe this design would keep the inside polyiso vapor barrier well above dew point under the most demanding winter conditions.

Insulating a block building from the inside

I have read all i could find on insulating a block building. It seems the best method would be to add foam to the outside. Unfortunately this is not in the budget for this project. The only mention of interior insulation seemed to be adding spray foam. The main building for this project is a two story from the 1930s with two later single story additions. Currently the inside has been completely gutted, while we hope to keep the outside intact.

Soil gas pipe capped in basement?

The is a soil gas pipe capped about a couple of feet from the ground in my basement. I'm looking at finishing my basement and am wondering if this needs to be vented to the outside or if I can go ahead and drywall over it. Why did the builders cap it?

Balanced ventilation year round when windows are closed?

I want balanced fresh air exchange to improve indoor air quality and reduce humidity in the winter. And also to improve indoor air quality and reduce humidity in the summer. It seems like hrv/erv are designed for only cold or only hot humid climates not a mix of the two.
