In the process that generates shadows on the solar collectors, the shadows that are generated by the building's own construction elements are taken into account. Illustrative examples of shadows produced by these elements are listed below:
- Shadows of horizontal slabs.
- Shadows of sloping roofs.
- Shadows of vertical walls.
- Shadows of columns.
- Shadows of guardrails or parapets.
It is important to mention that for these elements to generate shadows it is essential that the BIM model be up-to-date and import the architectural model again.
