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.
