Designing a passive solar / net zero house in NC Mountains

My wife and I are designing a new mountain home in Banner Elk, NC. We are in the initial design stages with our architect and are confused by the numerous options to consider. Our house will be built in the Eagles Nest community which has a pacific northwest lodge feel. Our home site is at a 5,000 foot elevation on the mountain ridge with a northern view.

Mitsubishi M-Series New FH vs. Old FE models

We're in the market for an M-series heat pump and dealers have been quoting us the older FE models rather than the newer FH models. Is it a mistake to purchase an older model that will probably be discontinued sooner rather than later? I would think so. Thoughts? Thanks.

Can rigid foam insulation have an air space between it and rim joist?

I am insulating my rim joists with 2" rigid foam board. Most of the rim joist is bare, and the foam fits along it nicely. Some sill boxes have some small irregularities (vent pipes, plumbing, etc) that I have worked around easily enough.

Home energy monitoring programs

I am building a net zero energy home to Passive House standards in the Seattle area. In addition to having it be as efficient as possible, my goals were to use renewable materials (no foam), eliminate thermal bridging. have a protected air-barrier and to keep the OSB warm. I'm using dense packed cellulose in the R-50 walls and R-85 roof (cathedral ceiling with parallel chord trusses). The wall assembly is a double stud system with an inner 2x6 load bearing wall and an outer 2x4 wall.

Do I really need 4 minisplits?

My wife and I own a lot in a development in the Pacific NW (Zone 4c), and we are planning to build our retirement house on it. We have never built a house before. Our projected house (which we designed ourselves) is 1,833 sq. ft. on one story, a modified California-style bungalow, as simple in geometry as we could make it.
