So my wife and I always wanted to build a dream house. If we did, short of moving out of province/country that would be our house until we are shipped to an old folks home or are wheeled out in a black bag, we're talking 40-50 years minimum.
That said I started looking into "Building Science" to design the most efficient and maintenance free house.
Things I've determined are:
External insulation is a must, minimum R-20. I'm thinking 3-4 inches of external closed cell spray foam from the bottom of the basement all the way up including the roof for a continuous air/water barrier that's also R-21 to R-28.
Metal siding and Roof. Most come with 50 year warranties
Ductless Heat pump + ERV for clean air around the house
There's much more I've come across but these are the major points. Have any of you recently done a high efficiency, a net zero or Net Zero ready (everything but the solar panels) home. I'm looking for suggestions and/or ideas to build smarter.
