I have some shading surface that theirs transparency change over a day. it means one of surfaces has 100% transparency and the rest have 0%, and the surface transparency changes one by one during such as figure below.

Everything is ok and I wrote the ems codes to manage the transparency schedules and it works well but I face this warning:

Too many figures [>=15000000] in a shadow overlap Overlapping figure=SHADING DA0, Surface Class=[Shading]

I've set th shadow Calculation as follow:

ShadowCalculation,

AverageOverDaysInFrequency,     !- Calculation Method
10,                               !- Calculation Frequency
15000000,                     !- Maximum Figures in Shadow Overlap Calculations
SutherlandHodgman,                !- Polygon Clipping Algorithm
SimpleSkyDiffuseModeling,     !- Sky Diffuse Modeling Algorithm
InternalCalculation,          !- External Shading Calculation Method
No,                           !- Output External Shading Calculation Results
No,                           !- Disable Self-Shading Within ShadingZone Groups
No;                           !- Disable Self-Shading From Shading Zone Groups to Other Zones

And set Output:Diagnostics object with the DoNotMirorDetachedShading option. (If I add more Calculation Frequency the E+ run will terminate).

What should I do?

Shading reduce the Cooling load, will these warnings change the amount of reduced load?

Can I ignore them warnings? image description
