Improving attic insulation and ventilation will have a much bigger effect
on your heating and air conditioning costs. My new house is over twice the
size of my old house. The winter heating and summer cooling costs are
lower in the new house than in the old house.

The attic in the old house was like an oven in the summer.

That is what my miserable little scuttle is like, I'd guess it is 120 up
there mid-day in the summer.

The attic temperature in the new house is barely warmer than outside.
The attic is so well ventilated you can feel a breeze moving through it.
