The problems associated with insulating brick, block, or concret walls vary depending upon environment, construction, and even sunlight. I is critical to get a for sure assessment of the overall situation. This is an instance where money spent on a documented professional consultant money well spent. I have come behind DYI folks many times....some of them ...

List of issues: Getting the space conditioned. This may be really easy or insanely difficult. Depends on what is on the other walls of bathroom and where your ducts are in your house. Getting electric. Should be no big deal. Getting water. Might be a bigger deal than electric but probably not a huge thing. Getting exit plumbing. Given that the ...

What he's suggesting would be to make the attic inside the building envelope, therefore you'd be heating and cooling the attic along with the house. You either need insulation at the attic floor or attic ceiling. One or the other is the building envelope. If you google some of the terms you can learn a lot. If the house is a standard, single open roof I'd ...

Building Air Standard (BAS) is sometimes referred to as BAS - ACH This appears to be a (I begin to think deliberately, after quite a few vague web results) slippery number to track down, but it appears to be essentially an estimation of "natural air changes per hour" based on the blower door test. Simply calling it "Estimated ACH" would apparently be too ...

Is the seal on the sump cover in good condition? Also, from the look of it the floor in question is the second level (i.e. half-dug next to a deeper, full-dug basement) correct? Only if you are really confident in the (other) sump pump in the lower basement should you consider doing anything at all to modify that pump well or piping. Sumps are not usually ...

Air sealing is more important than vapor sealing. All assemblies (wall and ceiling) need to be able to dry out. If you prevent air passage AND provide sufficient insulation to prevent condensation, you don't need or want an impervious layer. Cables,plumbing vents, ducts and lighting fixtures are notorious sources for air leaks. These can be stopped ...

Sounds like your concrete slab is un-insulated around the perimeter and/or the bottom. The very conductive flooring material (tile) doesn't help; the combination of these two means that the floor has very little thermal resistance to heat flow, so you constantly lose heat through the slab. If the heat you generate is quickly rising through the second floor, ...

To make long story short from what I see my best guess is that you have condensation issue. Most likely since your pump is in the corner there is somewhere thermal insulation missing and since you said that there is draft that means cold air is coming inside. Where from?.... I cannot be 100% sure. My money would be on the wall because most likely places ...
