The kitchen consultant on our project has specified a Hobart LT-1 LOW-TEMP CHEMICAL DISHWASHER. While most Hobart products are E-Star, this one is not. Is this type of dishwasher exempt as it functions somewhat differently?

I don't think it is exempt. According the the Energy Star page -
High and low temp stationary rack machines (undercounter; single tank door type; pot, pan, and utensil; and glasswashing) and conveyor machines (rack and rackless/flight type, single and multiple tank) are all eligible for the ENERGY STAR.
This sounds like a low temperature dishwasher to me.

The LT1 is a "fill and dump" machine and requires 120-140 degree water to it because it has no tank heater. LT stands for Low Temp. While not calculated, it affects sizing/recovery for the hot water heater that feeds it and puts chlorine into the sewer system. A component of Energy Star is idle energy, which is tank heat, but chemical machines typically have higher water usage and longer cycles as a substitute for tank heat. Water usage is also part of Energy Star and unless something has changed in its water usage, the LT1 would not be exempt because there are plenty of low temp dishwashers on the market that DO have tank heaters which allows for water to be re-used, (final rinse water becomes wash water) and qualifying water/energy usage. The LT1 is often selected due to either price, or the need to have a 120 v. machine. http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&u...
