Hi Karl Hofmann

Reading this old thread ,did you compare the results from both and if so was one more accurate than the other? I use the mistral program but I have been playing around with AC Calc. I am finding that the glass database figures are higher than mistral and this is having a significant effect on the overall cooling load.What did you think.

Any comments would be appreciated.
