BIA has a good paper on the subject at http://www.bia.org/BIA/technotes/t41.htm I first saw hollow brick in a form called "silo tile" in the 70's, when it enjoyed some short-lived popularity. It was a beautiful product, but water intrusion into the cavity and through the wall was a problem. The BIA article does a good job discussing the issue.
