<p class="MsoNormal">Marcus,<br>
It depends somewhat on what component you are using to model the attic. However, almost without exception, you need to define the slope and azimuth of the attic roof surfaces in your weather component (Type15 probably) and then pass the appropriate solar radiation
outputs from that component to the appropriate inputs of your building component.<br>
