Soffit situation – vented or unvented – GreenBuildingAdvisor

Question about soffits—I have a flat roof with trusses that have heels, and the attic will be conditioned from the heel inward.
The eave portion of the trusses will be 2×6 or 2×8 and sit outside the thermal envelope.
Do I need a vented soffit under the eave, or is an unvented soffit an option?
