Sysco Case Study 100+ food distribution centers (DCs) • Freezers, coolers, dock, and
dry warehouse space
Rolled out program in March, 2006 • Announced by corporate
management • Managed by project
engineering group
Aggressive goals: • 10% after 1st year • 25% after 3rd year • Another 5% by 6th year
Four-Prong approach 1. Corporate goal and
commitment 2. Energy Information Systems 3. Tune-ups at every DC in 18
months 4. Retrofits and high-efficiency

Summary • Energy is one of your largest controllable DC expenses
– Refrigeration is the primary driver • Energy efficiency has excellent ROI • Results can be measured and documented
– “You can’t improve what you don’t measure” • Your strategy must be comprehensive to have deep and
lasting impact – Measurement, benchmarking, O&M, retrofit, new constr.
• Energy efficiency is a critical part of any meaningful sustainability or “green” initiatives
