Design: I know it looks kind of confusing, but here it is.
KEY:
Yellow : Energy Ball Path.
Orange: Orange Portal Path
Blue: Blue Portal Path
Red: Player Path
There is one energy ball. The floor above, is a ledge, which an enemy is on. Like you see in portal, there's an energy ball launcher, and there's one at the bottom here. Fire a blue portal at the wall, next to the ledge, so it's facing the enemy, and fire an orange portal at the bottom of the energy ball launcher. The energy ball goes through the portal, and hits the enemy, killing it. Then you pass through the portal, and to the exit. I may build this design later for clarification.
