Exterior Light Levels

Can anyone tell me where to modify exterior light levels in the detail
design screen (not a wizard).

Additionally, in this same format, how do you rotate the building axis
for 90.1 appendix G purposes?

Thanks.

To modify exterior light levels, in Air-Side HVAC, look into your Electric Meter (EM1) properties and select the last tab "Direct Loads". You can modify the exterior direct load and the schedule there.

To rotate the building, in Building Shell, select Building Data Properties and you can rotate the building by changing the Azimuth field.

Another way to rotate the building is to create a parametric run. Got
to Tools, Create Parametric Run, I name the run 90 deg. Rotation (and
then 180 deg. For the next and finally 270 deg.). Run all the runs on
the baseline because you don't want the energy differences compounded.
Next Create Parametric Component - The component type should be
"Building Parameters". Under Data Modifications have the Category
"build parameters", Keyword "Azimuth", value "90" (then 180, then 270),
units "deg". This will give you all four orientations 90.1 appendix G
is looking for.
