APPENDIX D. ANNUAL ENERGY SIMULATION INPUTS AND RESULTS 

FOR COMMERCIAL REFRIGERATION EQUIPMENT 

D.1 INTRODUCTION 

This appendix presents further details on annual energy simulation inputs and results 

discussed in chapter 7, Energy Use and End-Use Load Characterization. Section D.2 shows 

tables of assumptions and inputs used in annual energy simulation. Sections D.3 through D.7 

present tables and figures of the simulations results for the commercial refrigeration equipment 

analyzed; this includes comparisons of CRE refrigeration load and daily energy consumption 

between the simulation results and the engineering analysis. Section D.8 summarizes the impact 

of different refrigeration system design options on whole building energy use. As discussed in 

chapter 7, the results shown in this appendix represent analysis conducted for the NOPR and do 

not represent analysis and results used in the final rule.
