Who says you need to sparge with hot water to get good efficiency. I just did a batch sparge with cold water (single sparge, two run-offs) and hit 86% efficiency into the kettle. This is about what I got with the same recipe last time when I sparged with hot water.
Recently I have been doing more thinking about efficiency and I found no reason why a cold sparge should hurt when batch sparging if all your conversion is done during mashing and no further conversion happens during lautering. In this case I hit close to 100% conversion efficiency in the mash so there would not have been anything to be converted during the lauter.
The wort never cleared up though. I assume that this was basically cold break that formed due to the lower sparge temp
