Doesn't that lack of insulation affect all heating and cooling technologies? Seems kind of orthogonal to me. Where insulation is poor, people - individually and/or through the government - absolutely should be investing first on improving it. But once that's done, we're back to the original question of what technology to use for heating or cooling the now-well-insulated space. Note that it's entirely possible e.g. for a furnace to have a greater capacity to heat a space while still being less efficient at it within any but the most extreme ranges.
