The house loses a total of 21,359 kW over the course of the entire winter. I took the total r values of all the surfaces, over their whole area, at the given temperature difference between exterior and interior, over the time in question - i'm using November 1 to March 31 - and got that figure. Kachadorian expresses it in Btu's, working in W/m2K as the insulative value, and m2 and K (otherwise known as degrees Celsius) the result comes out in watts.

Using the specific heat, in J/kgK (joules per kilogram per degree Celsius), i worked out that the thermal mass socks away 429,000 kJ for every degree Celsius it increases in temperature. Needless to say, it isn't a typical structure. Actually, it's a greenhouse, without going into details. If the design process yields a viable plan, then i can say more.
