Five-Phase Method: invalid results in daylight matrix

At first (quick) glance, my guess is that your window polygon is oriented backwards. Confirm the window normal faces out, toward the exterior environment and sky, by looking at the vertex order (right hand rule!).

Issue: the recorded values in the generated daylight_matirx.dmx are all equal to 0 (0.000000e+000)

Thank you,
