Well, not really...average longevity is significantly higher now than
turn of the century. At least some small fraction of that is
undoubtedly related to housing.
As for the other part, there's a lot of evidence both ways.
right? there's a right and wrong? it was certainly more efficient. These
overblown trophy houses are just rediculous.
and for years houses had minimal closets, smallish bedrooms and too
few bthrooms- that means it was the right thing to do?
Having lived in new construction (2000) standard 4 BR/2.5 bath and now
in a 1935 home I say a new home is 1000X better and easier to live in
than an old one. Yes the old one has nice chestnut trim but thats it.
If you don't have that option, fans can help. case in point, my house
- the roof ends right at the side of the house, no overhang -
therefore no vents there. PO's put on a new metal roof, so I am not
inclined to try to retrofit a ridge vent. The only vents are the two
in the end walls of the house. A fan in this application makes sense
to me, unless I were to have someone come in and reframe the attic to
put a modern-style roof on it, which sounds a lot more expensive.
I agree, the (newer) garage has a light tan/off-white seamed steel
roof, the attic fan in the garage was nonfunctional up until about a
month ago (I finally got around to replacing the thermoswitch.) Even
so it was always much cooler than the house which has a dark brown
aluminum fake-shingle roof. I wish they'd used the stuff that they
used on the garage on the house as well. I don't know how much
difference the color makes and how much is due to the garage being
shorter/more shaded, but it is significant.

An attic exhaust fan can help. Before we installed ours, we could
feel the heat coming off the upstairs ceiling, even though we have
reasonably good insulation (of course one can always use more, so
that's an alternative to reach the same goal). Now the ceiling is
cool. The downside is that the electricity to run the fan isn't
free. However, I think (haven't figured out how to prove, though)
that the decreased load on the A/C pays to power the fan, and the
A/C should last longer now that it isn't working as hard.
Remember, though, that typically only something like 20% of your heat
gain (as I recall) is through the ceiling.
It's all a big balancing act.

The facts are that heat enters the home via radiation, convection and
Its better and cheaper to use passive measures rather than electricity-
which costs more every day.
A white or light colored roof reflects the heat away from the inside
of the home.
Polyurethane insulation is better by far than fiber glass , its also
best when sprayed in as it takes up the shape of the space and fills
all the holes.
Polystyrene fitted under the ceiling stops the the remaining heat
conducted by the wood frame.
