a little help in calculating for sensible heat load from solar radiation...

[od1_cu3nc0]

i'm having a tough time finding the value of absorption, reflectance and transmittance for a tinted glass, does anybody know the exact values? i can't find it on the net, it just says that tinted glass absorbs about 40% heat from solar radiation.. is that right? need help please.. i'm currently designing a centralized 3-story office building with E/W orientation, and all the glasses we're tinted.. please help.. thanks
