When the absorptance is decreased, one would expect the heating load to increase and the cooling load to decrease. The overall energy difference would depend on which increased/decreased more.

When I reduce the roofing material absorptance value in my model, under construction properties, my energy consumption increases instead of decreasing, which suggests that this input is actually reflectance and not absorptance. has anyone experience something similar or am I missing something here? Any input is much appreciated.
