We are working on a project that is pursuing LEED v4: New Construction. This project is a plasterboard manufacturing plant, in which an important part of its energy consumption is produced by manufacture equipment (unregulated loads). We want to demonstrate that their process is more efficient than conventional standards, and following the exceptional calculation in section g2.5 of ASHRAE 90.1 2010. Also we use the document ANSI/ASHRAE/IES Standard 90.1-2010 Performance Rating Method Reference Manual, in this document regarding the process loads says that “with approval of the rating authority, variations of the power requirements, schedules, or control sequences of the equipment modeled in the baseline building from those in the proposed design shall be allowed by the rating authority based upon documentation that the equipment installed in the proposed design represents a significant verifiable departure from documented conventional practice. The burden of this documentation is to demonstrate that accepted conventional practice would result in baseline building equipment different from that installed in the proposed design”.Therefore, we believe that we can demonstrate this saving percent in the process energy. Is it correct? Further for this purpose, Can we use as a reference the LEED interpretation ID #10159?

Yes you can claim savings in the process loads. You will need to determine the savings against a baseline that is standard industry practice. So be sure to include a justification for the baseline that you will be comparing to.
