Presentation Transcript

  1. Cold Storage Challenges and Good Practice at UoEdinburgh Martin Farley – Laboratories Facilitator, SRS department Martin.farley@ed.ac.uk

  2. Background • Position created through combination of: • Currently ‘Laboratories Facilitator’ under SRS department, very needed

  3. UoEdinburgh – Labs facilitator Run Edinburgh Sustainability Lab Awards Act as a resource for lab-sustainability issues Scope, identify, (ideally) improve problematic areas

  4. Issue at hand • How many freezers are there? • How much do they consume? • How much energy do they cost? • No UoE wide SOP

  5. ~355 at UoE, ID’d locations and estates costs • Made cost approximation (conservative estimate of 12.5 kWhr/day/freezer) • Running of our 355 freezers - ~270,000GBP (raise avg running to 13.5kWhr, rises to 280,000, 15kWhr rises it to 300,000) • Conducted energy study at varying temperatures

  6. Running Temperature

  7. In Progress . . • Roslin institute has excellent SOP, • Needs standardisation across UoE • Exit Policies – Huge potential • Inductions for good practice

  8. -40C -> -20C • Wellcome Trust Clinic and Genetics Centre are merging freezer rooms • Looking at replacing -40Cs with -20Cs • Primarily DNA storage • Ideally would allow consolidation of fridges

  9. Freezer Farm – Cooling the rooms • In initial stages – want to replicate Roslin’s cooling techniques • Looking at recapturing heat if possible • Utilise cool Scottish air to cool 90 -80Cs as well as -150C room. • Fans are only triggered at two temperatures

  10. Long-Term Cold Storage Study • 3 stage, 3 freezer project • 1. Short-term studies (response times with power cuts, energy loss with door openings, UoE) • 2. 5 year study. Look at energy consumption/internal temps/sample viability at -80C, -70C, -60C. (VWR) • 3. UoE continuation of project.

  11. Final remarks . . . • Multi-pronged approach • Huge (and growing) potential • Long-term study to help push larger scientific community – Your input is welcome! • Contact for survey
