Our house (bought 4 years ago) has a system installed from the previous owners/builders.
Draws air from 1 pipe under the 3 car garage slab via basement wall access, and another pipe under the basement slab itself. It runs 24 hrs/day - 365 days a year. Each vented area is backfilled with gravel to allow "air" space.
