I have a question concerning models and their positioning in RADIANCE when considering the contribution of daylight. I have a model of a building with rooms at different levels, cut out from a bigger complex.
This means that, for example, my entrance is located at a level of (z= -5), a negative value, as z=0 is positioned in correspondence of a part of the bigger complex that is not of my interest and will not appear. While the model has to be absolutely rotated in order to have the Y matching the actual north of the place before being imported in RADIANCE, I am not sure if the model should also be shifted on the Z, for example, to reproduce the actual meters above the sea level…
Thank you for your help!
