Sun path diagrams are used to read the solar azimuth and altitude throughout the day and year for a given position on the earth. They can be likened to a photograph of the sky, taken looking straight up towards the zenith, with a 180° fish-eye lens. The paths of the sun at different times of the year can then be projected onto this flattened hemisphere for any location on Earth.
- Azimuth Lines – Azimuth angles run around the edge of the diagram.
- Altitude Lines – Altitude angles are represented as concentric circular dotted lines that run from the center of the diagram out.
- Date Lines – Date lines start on the eastern side of the graph and run to the western side and represent the path of the sun on one particular day of the year. In Ecotect, the first day of January to June are shown as solid lines…
