Grocery Store Measures Door Gasket, Automatic Door Closers, and Strip Curtain Laboratory Testing
History Door Gaskets and Automatic Door Closers are included in EnergySmart Grocer Program; Strip Curtains are not. 40% of California’s Program. So far, over 4 miles of door gaskets have been installed in BPA’s Program. The Program claims 0 energy savings – anticipating results from more detailed M&V.
History (cont) RTF Subcommittee recommended lab testing in lieu of field testing to minimize the number of uncontrolled variables. After months of searching, one laboratory (Emerson Technologies) was found that could and would perform the desired testing. Emerson was contracted to conduct a literature search on door gasket energy savings and finalize testing plans (Phase 1).
Phase 1- Literature Search & Lab Testing Plans
Lab Testing Plans
Lab Testing Plans (cont) 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
Lab Testing Plans (cont) Automatic Door Closers Use results from Door Gasket Lab Testing (No Gasket vs. Fully Functional Gasket). Gather field data on typical door open times. With Automatic Door Closer Without Automatic Door Closer
Phase 2: Laboratory Testing - Expected Outcomes Assessment of the importance of door gaskets on energy use of refrigerated cases. Projected annual energy savings at test conditions for Door Gaskets, Strip Curtains, and Automatic Door Closers. Additional tests?
