Heating in LA ?
Thats three times the power needed for (our) house in Galway, Ireland. Purely heated electrically !
(with wind power contract). The house is well insulated, though.
They need to heat the place in LA in winter ? The outside temps average13 C in January ... you could keep the house toasty with just proper glazing to absorb the heat (we do!). The house is nowhere near the German Passive standards that are becoming the housing regulations across Europe. Far from being particularly impressive, it would be unsaleably wasteful in Europe in the next decade.
