Radiant barrier alone is not insulating, so it would not help keep in the very expensive AC air... does reduce the need for cooling (does nothing for VOG)much like an umbrella on a sunny day....
Even the radiate barrier with insulation bubbles (we have in our house) has a very low R value, so I would not use it alone, if I were looking to use AC...
It really does reduce the heat radiating in through the walls & ceiling, so that would reduce the amount of cooling needed (but would do nothing for the VOG)
