1. Northwest Power and Conservation Council Preliminary Cost-Effectiveness Energy Star Tier 2 Vending Regional Technical Forum 19 September 2006

2. Northwest Power and Conservation Council slide 2 Preliminary Cost-Effectiveness Assumptions Tier 1 is baseline for new & refurb Tier 1 is baseline for new & refurb 12 year machine life 12 year machine life 6 year remaining life for existing machines 6 year remaining life for existing machines Refurbs every 6 years Refurbs every 6 years Life after refurb is 6 years Life after refurb is 6 years Machine savings shaped like residential refrigerator Machine savings shaped like residential refrigerator Off-hour control savings shaped like Vending Miser Off-hour control savings shaped like Vending Miser

3. Northwest Power and Conservation Council slide 3 Preliminary Cost-Effectiveness Cases to Consider New Machine: New Site or Replace Existing Machine at End of Life Early Replacement: Early Replacement with New Tier 2 Machine Refurb: Refurbish Existing with Tier 2 Kit Savings – T1 minus T2 for 12 years Savings – Add 400 kWh/year with controls enabled Savings – Exist minus T2 for 6 years plus T1 minus T2 for remaining 6 years Savings – Add 400 kWh/year with controls enabled Savings – Exist minus T2 for 3 years plus T1 minus T2 for 3 years Savings – Add 400 kWh/year with controls enabled

4. Northwest Power and Conservation Council slide 4 Savings Assumptions Measure Savings (kWh/year) Existing Machine to Tier 1 1300 Existing Machine to Tier 2 1740 Tier 1 Machine to Tier 2 440 Tier 1 Machine to Tier 2 Refurb Kit 545 Enable Off-hour controls on Tier 2 machine 400
