Hello All,

I am working on a energy simulation model following Appendix G of
ASHRAE 90.1-2004.
In this appendix, table G3.1, under the building envelope category
specifies that for roofs- insulation is entirely above deck but does
not specific the kind of construction. Can I use any kind of material
(like RCC, cast concrete or a metal frame) with insulation above deck
to meet the required U value. Please clarify.

Thanks & Regards,

Sambhav Tiwari.
