I have a large house in Phoenix which costs way too much
to air condition in the summer (~600/month on a peak deman
rate with a good load controller). I am interested in
measuring where the heat is coming in (quantitatively)
so that I can calculate the efficiencies of various alternative
fixes.
I have tried measuring surface temperatures of glass, brick, etc
without good results (I can calculate roughly the glass loss
and it's not too awful).
Does anyone know how these things are done. Can I buy thermal
infra-red film and shoot pictures and get reasonable (<1 degree F)
temperature resolution? Are there other ways to do this?
Thanks. I will post replies if I get enough
and others are interested.

I would assume that wherever the heat is coming in during the summer, that will be where it goes out during the winter. That's an easier problem to tackle, since the "smoke test" done by heating companies can find those spots. Granted, this won't show you things like thermal transference through glass, but you might be surprised at how much sealing up those little drafts will help. Teri Miller Mail?
