Radiant Barrier Savings Calcs
I know there is a monster radiant barrier thread here http://hvac-talk.com/vbb/showthread.php?t=112101 , I thought it best to start a new one for my specific question.
Anyone use the radiant barrier and increasing insulation savings wotksheet at the DOE ORNL site, here http://www.ornl.gov/sci/roofs+walls/radiant/rb_05.html ?
I'm not getting the calcs to predict great savings for my home that I expected. Anyone else look at those calcs? Did it persuade your decision on an RB or not?
