Energy+ Error messages importance

Chris and Mostapha,

I am running a quite straightforward analysis and the report of the energy+ component give a lot of Warning and Severe Errors, which I can t understand why and how important they are in terms of the accuracy of the results.

I create all the zones manually.

A typical Sever error that appears a lot:

1655.    ** Severe  ** Problem in interior solar distribution calculation (CHKBKS)

1656.

1657.    **   ~~~   **    Solar Distribution = FullInteriorExterior will not work in Zone=B

1658.

1659.    **   ~~~   **    because vertex 1 of back surface=AEE6C33C649E4766B07E_GLZ_4 is in front of receiving surface=13E6D018E20B4FD49885

1660.

1661.    **   ~~~   **    (Dot Product indicator=156.6677)

I attach the error report.

Any advice on any of the errors would be highly appreciated.

Attached some images, that show the flats, which I consider as separate energy zones, that I built manually and assign honeybee materials.

Thanks,

Dimitris
