Heating System requirements for New House

I never got a chance to see the mechancals of the house, but I can tell you that the construction is nothing like conventional. There's nothing difficult about it, but the engineering done beforehand has to be top-notch. Right from the site work, to positioning of the house and its orientation to the sun. There can't be any guesswork involved.
