Pacific Northwest National Laboratory recently published a technical report titled ASHRAE 90.1-2010 Performance Rating Method Reference Manual. This work was funded through DOEâ??s Building Energy Codes Program. The report is intended to be a reference manual for the Appendix G Performance Rating Method (PRM) of ASHRAE Standard 90.1-2010. The procedures and processes described in this manual are designed to provide consistency and accuracy by filling in gaps and providing additional details needed by users of the PRM. This document builds from existing reference manuals including the Nonresidential Alternative Compliance Method (NACM) and Commercial Energy Service Network (COMNET) and has undergone an extensive vetting and review process.
Potential users of this manual include energy modelers, software developers, and implementers of â??beyond codeâ?? energy programs. Energy modelers using ASHRAE Standard 90.1-2010 for beyond code programs can use this document as a reference manual for interpreting requirements of the PRM. Software developers of tools for automated creation of the baseline model can use this reference manual as a guideline for developing the rules for the baseline model.
