Does anyone know where to find the values of solar, thermal, and visible absorptance of building materials?

edit

Hello, i suggest view some examples of materials with their thermophysical properties go to EnergyPlus console then IDF Editor, open the .idf of ASHRAE materials, then you will see examples of materials with their ASHRAE data values.

here are some values, i had use this page: For the thermal absortance aka emmissivity http://www.engineeringtoolbox.com/emi... http://www.engineeringtoolbox.com/rad...

For the solar absortance aka the complement value for the reflectance or reflectivity values http://www.engineeringtoolbox.com/sol... example: White Dutch tile has an 0.18 solar absortance value, then has an 0.82 reflectance value

for windows you can use a software named "WINDOW7" which can couple with energyplus and has the properties of many windows
