[Equest-users] Roof reflectivity, emissivity and absorptance in equest

[Jeff Ross-Bain]

Hi All,

 

ASHRAE refers to roof properties in terms of reflectance, emittance, and SRI
(Appendix G Table G3.1 5c). However, eQuest uses absorptance. I am unable to
find in the eQuest input areas (wizard and detailed) where there is a means
to input values other than absorptance. Is there a conversion factor, or a
place to input reflectance, and emittance or SRI that I am unable to find?

 

Many thanks for your comments.

 

Best regards -
