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 End­Use 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.
