Looking for some thoughts from those in the know regarding what is the best construction methods from both an economical and energy efficient point of view. Granted every house is different but assume a regular shaped storey and a half 2100 sq ft

External insulation seems to be leading the way of budget allows and it can be designed in from the start.

Do you mean this is the cheapest option out there? Whats the usual build up - block on flat, plastered inside with external insulation and suitable external plaster?

Nope, not the cheapest but one of the best with regards to thermal envelope, thermal mass etc

What time frame, interest rates, inflation rates and energy prices have you got in the financial model underling the full LCCA for this 2100 sq ft gaff?

Id wholeheartedly agree with this. You actually cannot muck it up. When you think about it the whole house is encased.

Commence late summer with a 12 month build. Interest rates wont apply. Using 3% annual inflation on todays prices over 35 years

What about air tightness and how would it compare in cost to alternative methods?

Have you looked into natural materials like straw for insulation, cob for thermal mass. A post and beam timber frame will hold up your roof and allow you to completely envelop the structure using non-load bearing walls with high insulation value.
