10 Lab Testing Plans Door Gaskets 3 Cases: Low Temperature Walk-In, Medium Temperature Walk-In, Low Temperature Reach-In 3 Conditions: No Gasket, Typical Damaged Gasket, Fully Functional Gasket Strip Curtains 2 Cases: Low Temperature Walk-In, Medium Temperature Walk-In Automatic door opening of 4 minutes/2 hours. Compare to Fully Functional Gasket

11 Laboratory Testing – Interim Results Completed testing and report on low temperature reach-in. Completed testing and report on low temperature walk-in. Completed testing on medium temperature walk-in – report in 1 week. Completed testing on strip curtains – report in 2 weeks.

15 Lab Testing vs Real World

16 ESG Program Changes Currently - assign 0 kWh/yr to door gaskets and closers for approx. 10 miles of installed gaskets and over 150 automatic door closers. Now – Assign energy savings based on lab testing (slides following).

17 Estimated Annual Energy Savings Gaskets - Tested

18 Estimated Annual Energy Savings Gaskets – Proposed

19 Estimated Annual Energy Savings Auto Door Closers (= No Gasket)

20 Next Steps Complete test reports on Medium Temperature Walk-In and Strip Curtains. Evaluate results with wider audience including peer review. Incorporate revised results into ESG, as appropriate. RTF provisionally deemed measures
