We have an industrial plant where the process loads are assumed to be, say, 98% of all building energy use. Therefore, even if the non-process building portion was Net Zero Energy, we would not meet the minimum LEED-NC 2009 prerequisite of 10% energy reduction. However, the process equipment specified appears to be new and with exceptional energy performance over traditional equipment. The Question: Can we meet the prerequisite (and maybe get points) by demonstrating a 10% (or better) energy improvement primarily through process load savings? This would employ the Exceptional Calculation Method. Assume the rest of the building meets or exceeds ASHRAE 90.1-2007 and is modeled according to the rules. Thanks.

Jeff, I had a similar issue with a heavy manufacturing plant project. I think the following LEED Interpretation would be helpful for you. http://www.usgbc.org/leed-interpretations?keys=10291

Hi
what is the procedure to claculate "Exceptional Process load" and Savings?
1--Some sfoftware such as HAP-V6 can calculate the process load with respect to schedules, so we still need to calcuate the "exceptional Load" separately?
2--Li# 10291 recomends to simulate both with process load and without proccess loads, i cant understand the interpretation and have the confusion, how to calculate the SAVING to earn points?
3--Li# 10493 recommends to earn points in Core n Shell catagory, as i understand. Simulate the project and claim the saving in category core n Shell(CS) instead on New Construction, it is correct understanding?
4--Ashrae table for motor mentioned 60 Hz motors, Can we consider 50 Hz motors as non-regulated load?
I need to understand the rightway or the approperiate way to earn credits/points for an industrial project with "High-Process load.
