Has anyone successfully modeled a regenerative elevator for LEED compliance?

I see a lot of literature claiming 50%-75% savings, but I'm not sure if/how I should change the schedule and/or peak load in the model.

Or should I just put the elevator on a separate electric meter, and take a percentage cut in an exceptional calc.

It's a 25 story building with 4 passenger elevators.

Thanks.
