I want to change the solar absorptance/reflectance of roof outermost layer based on outdoor temperature Dry bulb Condition is Solar reflectance = 0.85 for DBT >30 Solar reflectance 0.1 for DBT <30. Based on research, I've a little idea that it is to be done using EMS. But I really don't know how to use it. I've to use it on a DOE prototype strip mall building in open-studio. Any help in this regard is highly appreciated.
