Hi,

I am getting following warnings while running my model:

WARNING***Custom weighting factors cannot be calculated for SPACE P Public

Toilet since it has fewer than two opaque surfaces. ASHRAE

this space.

The warnings are repetitive in nature.

Can someone guide me on how to resolve these warnings?
