Yes hard to believe but those pesky recessed can lights may be pulling air in from the attached garage, or humid wall cavities, the soil and combustion exhaust vents.. Impressive your existing home tested as low as 1.6 ACH50. I think your rater's comment about being between 2 and 3 are ideal for that particular rater's desires, not the homeowners. It may be a sweet spot for them, because they have tightened up the house enough, without being burdened the details of adding outdoor air ventilation (as often provided by HRVs.) 3 ACH50 is the threshold often calling for outdoor air ventilation, not 2 so they may be slightly mistaken if that's their reasoning. Even homes as leaky as 3-7+ ACH50 probably benefit from outdoor air ventilation systems. Leaks happen when you don't want them (cold, windy rains, large temperature difference between indoors and out) and don't leak enough the majority of the time as you want a constant supply of fresh, outdoor air. All new homes should include outdoor air ventilation, which means there is no such thing as too tight. Canada's R2000 efficiency program calls for 1.5 ACH50 and passive house calls for .6 ACH50, five times tighter than 3, Energy Star and international code minimum for most climates. Getting your new home as tight as your existing home is a great minimum goal, it might be cost-effective to do better. I think all homes get more leaky over time which is why it's important to use quality materials with good workmanship and replace worn out weatherstripping. Leaky homes getting leakier is a lot of leaks.

Not a fan at all of this plan. The exterior is not attractive, and the floor plan is not good. You walk in the front doors and the sightline is straight to the kitchen sink. No foyer, no coat closet, no powder room. All of the bedrooms have only one exposure, and one of the two windows in the master bedroom is off a covered porch, allowing very little light and air in. The dining room is a walkway to a bedroom and the porch, so furniture placement will be difficult. Indeed the entire living space is a thoroughfare to other rooms. I'd start over.

Thanks Kevin. Frost protected shallow foundation from the cold climate research center. And I just finished up getting the 4" xps pinkboard 250 installed around the entire perimeter. And have a stack of pinkboard r10 to install around the outer perimeter. While you're at the ccrc website search furring out a wall. Yes placing the insulation on the inside violates the 2/3 rule on insulation. The pinkboard on the inside in not taped because the vapor barrier behind it. The semi permeable pinkboard is only a vapor retarder and will not absorb moisture. This wall is intended to vent to the outside. With 1/2" cdx plywood and tyvex rain wall. 3/4" air gap screened on the top and bottom created by the 1x2 nailers installed on the studs 16"oc. Siding on top. The inside pinkboard is installed using minimal plastic washer headed nails. Then 5 rows of 1x4s installed horizontally with 1x4s installed over them vertically on the studs with 7 " timberlock screws. Making minimal holes in the vapor barrier. The windows and doors are furred out using 2x4s on edge, 3-1/2" directly to the rough framework around them. Doors will have a 3/4" boards glued n nailed to the edge of the door jams to extend them out. Fairly easy task. And I will not have to drill holes in the outer walls to pull wires or run utilities. No obstacles to insulate around. Just put it in n straighten it up. This reduces man hours for me also. I'm still building and finally got the roof finished. Carpenter's are booked and not available so I'm mostly a 1 man crew with help from family. Lot of work as I started with acre of trees. Well, septic, electrical utilities are all in. Now I can start drying things out. Then insulate. I will put our new fuel oil drip stove in, Kuma classic. Covid took a month. Again, I do realize that this is a non typical type of construction method. We have unique insulation needs, and I'm willing to try and do something better. And believe the methodology. And your comments make me challenge that, thanks. It was mentioned that I'm comparing this build to the average home built in our area. Guess I thought that would be appropriate. And yes the standard construction method in these parts is 2x6 walls with batt insulation. Some still using fiberglass insulation instead of rockwool. The only difference is that I'm adding the 2" pinkboard inside. And the furring strips for sheetrock. And yeppers tooooo late for changes in foundation. Our inspector said he was impressed with the work and it was do better then what he usually sees. The roofing contractor comments were all positive.
