Hi all
I'm trying to find how to change the reflectance of internal surfaces (I need it for lighting studies). According to the "Engineering Referenc", page 150 "The reflectance values for opaque surfaces are calculated by the program from the Solar Absorptance
and Visible Absorptance values of the outer material layer of the surface's construction." and according to page 136 in "Output Details/Examples": "Reflectance is defined as one minus the thermal
absorptance." explaining the output of the Envelope Summary report.
Could anybody advice in how to change the reflectance of internal surfaces and how it is being calculated in E+
Thnaks
