RE: [EnergyPlus_Support] Insulating wooden floor raised 400mm from ground in temperate climates

Thanks DR Li,
My specialty is advanced envolopes, PCM's included.

I missed one thing in my rather messy post below, spray foam has the
best performance but is expensive. If your client does not have an
appitite for the cost of all foam than you might suggest a 'flash and
batt', involving a single coat of spray foam (about 3 inches) and then
fiberglass batts on top.  This would provide the airseal for the
surface and stop thermal bridgeing efficts, (foam) maximize resistance
(thick as possible batts) at a lower cost than if you used strictly
foam. There also is a benefit in applying a radiant barrier to the
outside of the fiberglass batt (do this by changing the solar
absorbance to a very low number like 0.01)
