As a result

As a result…

  • Funding, staffing and student hours limit

    • Campaign duration

    • Campaign scope

  • therefore, selecting the best strategies is critical to create enduring change

Case study 1: Fume Hoods


Short term intervention long term change two case studies from the university of toronto

Case study 1: Fume Hoods

  • Fume hoods use incredible amounts of energy

+

>

+

  • Fume hoods exhaust large volumes of air

  • Exhausted air must be replaced with fresh supply air

  • Supply air must be heated/cooled

    Less exhaust

     less supply air

     less energy to condition supply air


Case study 1 vav fume hoods

Case Study 1: VAV Fume Hoods

  • Goal: Minimize air flow through fume hoods, while maintaining or improving safety

  • Encourage fume hood users to position sashes

    • as low as possible when not in use

    • at safe working height when in use


Case study 1 fume hoods

Case Study 1: Fume Hoods

  • 1) Awareness raising

    • presentation

    • website

    • visual prompts

  • 2) Competition

    • ‘Sash Patrol’

    • stamps

    • prizes

Case study lessons learned

Case Study: Lessons Learned

  • program endurance

  • use of commitments

  • ‘ownership’ of the campaign (discussion vs. lecture)

  • competition

  • first pilot

  • positive results


Short term intervention long term change two case studies from the university of toronto

Case study 2: Printer Defaults in Libraries

  • expansion to Central Libraries

  • information & awareness (site specific)


Case study 2 results of uptake

Case study 2: Results of Uptake

Proportion of jobs double-sided

Sheets of Paper Saved In Libraries

  • Sheets actually used since initiatives started (up until June 2011)1,823,789

  • Sheets that would be been used without increase in double-siding 2,745,694

  • SHEETS SAVED SINCE INITIATIVES STARTED 921,905

  • (A PERCENTAGE REDUCTION OF) 34%

  • PREDICTED ANNUAL SAVINGS (based on calculated 756,421

  • percentage reduction)


Lessons learned

Lessons Learned

Defaults did lead to incredible results, however…

  • opportunities to default

  • cost of technological change

  • intrinsic motivations present?


Concluding thoughts

Concluding thoughts

  • importance of evaluation

  • consideration of tools (i.e. competition)

  • technological and behavioural opportunities are unique for each project
