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

I am trying to run a simulation of local residential buildings. Most building's material properties are found in ASHRAE. Can you let me know where to find solar absorptance, thermal absorptance and visible absorptance for different materials used in building construction such as walls, roof, windows , etc...?

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

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
