2 Dartmouth Green Labs Outline Big Science. The Case for Green Labs at Dartmouth Why Focus on Freezers? Success Stories Small Footprint. Dartmouth s Chill- Out IniFaFve

3 Making the case for Green Labs at Dartmouth 20% campus footprint 90 40% campus energy Federal Awards (millions)

4 Why are labs such energy hogs? HVAC System EssenFal Equipment Run 24/7 Phantom Load Lights

5 Culprits in the biochemical/biomedical/biological lab

6 Why focus on ultralow temperature (ULT) freezers?! EssenFal for storage of biomaterials/biomolecules! Run 24/7! Consume 10x energy of an energy star - 20 C freezer kwh/day 20-35kWh/d x 365d x $0.095/kWh = $1,000/year per freezer ~200 ULT freezers x $1,000/yr = $200,000/year

7 Where are the savings?!!!! Regular maintenance Reduce inventories ReFre, Share, Replace Temperature tune from - 80C to - 70C -70 C -80 C 2-4 kwh/day 10% energy ~$100/yr/freezer saved

8 What are the risks? Freezer inventories are ozen not known Contain old, unwanted, poorly labeled samples Stress on the compressors to maintain temp Increases chance of freezer failure Lost samples, archives, data Cost to insftufon >$100,000 Biohazard release/exposure

9 CDC: SUCCESS STORIES! 60 ULT temp tuned to - 70 C refred 44 ULT freezers discarded 96,000 unneeded samples (30% of samples inventoried) CU Boulder: 50% ULT temp tuned to - 70 C 7 freezers refred 6 shared UC Davis: saved $26,700/yr = 350MkWh/yr CDC, CU Boulder, Genentech, Harvard, MUSC, Penn State, Stanford, UC Davis, UC San Diego, UC San Francisco, UNC Chapel Hill, UPenn, Yale Benefits to scienfsts: Easier to find samples with organized freezers Save grant $$ - expensive freezers last longer with proper cleanout and maintenance Beaer for experiments - keep samples fresh and up to date

10 Dartmouth Chill- Out IniFaFve

11 Dartmouth Green Revolving Fund (GRF) Green Revolving Fund =$1M commitment Launched in 2011 Savings incurred from energy efficiency projects gets reinvested into the fund Dartmouth founding member of the Billion Dollar Challenge " encourages colleges & universifes to invest a combined total of $1 billion in self- managed GRFs that finance energy efficiency improvements CGF FaciliFes/OperaFons Efficiency Projects GRF $1M

12 Goals of the Chill- out IniXaXve Provide roaming ULT backup freezer, freezer maintenance kits, and educafonal materials to parfcipafng labs Provide compeffons and incenfves for parfcipafon Reduce annual electricity consumpfon of ULT freezers by 10% by 2020

13 SXrling Ultracold Freezer Humm Free Piston SXrling Cooler " Heat is extracted through cycles of heafng/cooling of a fixed amount of He in a free piston " No HFC refrigerants, which are ~17,000x more damaging to environment than He " No mechanical linkages, oil, or lubricafon (uses gas bearings) Notable features: " Uses 50% less power (ave 11kWh/d) " Generates 50% less heat " Fastest inifal pull- down to - 80 C " Fastest door opening temperature recovery " Slowest warm- up azer power outage

14 ObjecXves of the Chill- out IniXaXve ObjecFve 1: " Temperature tune - 80 C freezers to - 70 C " Replace old freezers with energy efficient models " ReFre old freezers " Educate researchers in freezer maintenance and energy efficient freezer models ObjecFve 2: " Support researchers in generafng freezer inventories

15 The Plan 5 Phases Phase I: " Generate campus ULT freezer inventory " Create educafonal materials " Assemble freezer maintenance kits " Purchase SFrling backup freezer " Measure SFrling energy consumpfon against a standard ULT freezer to esfmate savings that may be incorporated into future rebates Phases II- V: " Backup freezer will rotate between labs in an enfre building before being transferred to the next building on the schedule

16 The Plan cont Freezer rotafon schedule will be generated at the start of each phase Labs will have freezer for 1 week or longer as needed ParFcipaFon is voluntary Labs must sign a waiver/agreement to parfcipate CompeFFons and incenfves offered during each Phase: " Pizza parfes, local restaurant giz cerfficates, raffle drawings for prizes for temperature tuning, creafng/submirng an inventory, etc. " Special RecogniFon Awards: Frost Champion frosfest freezer photo Waste Warrior most samples discarded Rip Van Winkle Award oldest sample discarded Zero Carbon Crusader refre freezer without replacing Prius Award replace freezer with more energy efficient model Lorax Award reduced inventory enough to share freezer space with another lab

17 AnXcipated impacts Economic & Environmental $K MWh/ yr

18 AnXcipated impacts Social & Safety Social Impacts Directly engage and benefit the end- user, the researcher Roaming freezer will market the Green Labs Program, safety and sustainability Fps/pracFces Success used to leverage future lab sustainability projects Big Science. Safety Impacts Reduces risk of freezer failure Freezer inventories key in emergency situafons Fulfills Dartmouth s role in the NaFonal Biosafety Stewardship Commitment Small Footprint.
