Message-ID: <1488@anasaz.UUCP> Date: 7 Dec 88 17:48:29 GMT Organization: Anasazi Inc., Phoenix AZ Lines: 22 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. -- John Moore (NJ7E) {decvax, ncar, ihnp4}!noao!nud!anasaz!john (602) 861-7607 (day or eve) {gatech, ames, rutgers}!ncar!...
