Dennis,
In post an pier construction, piers are placed in parallel rows, spaced every 6'-10' apart and 6'-8' on center. Posts and diagonal bracing extend up to girders which support the floor joists upon which is installed the plywood subfloor, generally glued and nailed to the floor joists. This creates a seal. The crawl space below is vented or open for outside air to circulate freely. Some choose to insulate under the subfloor, but not really needed in Hawaii's climate.
