Hello, i suggest to 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. Greetings from Merida, Yucatan, Mexico community!

Hello, i suggest to 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. Greetings from Merida, Yucatan, Mexico community!

here are some values, i had use this page: For the thermal absortance aka emmissivity http://www.engineeringtoolbox.com/emissivity-coefficients-d_447.html http://www.engineeringtoolbox.com/radiation-heat-emissivity-d_432.html

For the solar absortance aka the complement value for the reflectance or reflectivity values http://www.engineeringtoolbox.com/solar-radiation-absorbed-materials-d_1568.html example: White Dutch tile has an 0.18 solar absortance value, then has an 0.82 reflectance value
