It seems that in this super modern age of bridge the low-level penalty double is obsolete. But surely most of us still play that a double of a weak 1NT opening as basically a PENALTY double? What do you need to double a 1NT opening? I go along with the theory that if you have a better hand than the 1NT opener, you should double. If you're playing ACOL opponents that means at least FIFTEEN high card points if your hand is balanced, or seven reasonably certain tricks, e.g. a solid suit and an outside entry. But let's just stick to the “15+” one for now.
