Reduce Building Energy Use Through Occupant Engagement

Enhancing Energy Conservation and Efficiency with Occupant Engagement Presenters: Andrew Pape-Salmon Director (on sabbatical), Energy Efficiency Branch BC Ministry of Energy, Mines and Petroleum Resources David Helliwell Co-founder and CEO Pulse Energy

Overview • Case Study – Jack Davis Building • Lighting Energy Conservation Campaign • Tools Employed: Social Marketing and Energy Information Systems • Results and Conclusions

Case Study: Reducing Energy in an Office Building – Jack Davis Building • Power Smart commitment: reduce internal electricity demand by 9% by 2009 and by 20% by 2020 • Carbon Neutral Government by December 31, 2010 • Initiatives: – Modest technology and building retrofits – Launch of a Green Team – Workstation tune-ups – Green Pledges

Lighting Energy Conservation Campaign • Lighting retrofit in 2008 installed: – photo sensors and dimmable ballasts on floor #4; – Light switches on floor #5; and, – Occupancy sensors in meeting rooms and washrooms. • July 2009 campaign aimed to achieve deeper savings through engagement of 200 employees • Used an Energy Information System (EIS) to provide immediate feedback

Tools Employed • Community Based Social Marketing (CBSM): – Communication – concrete, targeted, vivid, interactive – Prompts – Empowering champions – Convenience (remove barriers) • Feedback and Energy Information Systems: – Real-time information – Combination of tables, text and charts – Monitoring of the specific end-uses (lighting on each floor) – Dashboard on the Intranet (no login required) – Comparison with control case (average annual demand)

Lighting Energy Conservation Campaign: Results Energy Savings 12.0% 12.6% 2.4% 4th floor 5th floor (occupant 6th floor (no (automated day engagement) retrofits) light dimming)

Lighting Energy Conservation Campaign: Results • Prompting had observable effects on behaviour 5th Floor Lunchtime Electrical Demand 9 Electrical Demand (kW) 8 7 6 5 Avg. Electrical 4 Demand from 3 12:15-1pm 2 1 0

Lighting Energy Conservation Campaign: Results • Clear relationship between energy savings and visits to energy information tool dashboard:

Lighting Energy Conservation Campaign: Conclusions • Occupant engagement achieved electricity savings of 12% over and above the impact of installing new energy efficiency technologies • Key factors for successful occupant engagement: – Designate an energy champion – Customize information to specific actions being promoted – Use timely email prompts – Display comparison information

Lighting Energy Conservation Campaign: Conclusions • Energy Information Systems play an important role in occupant engagement by: – Improving the effectiveness of CBSM tools – Helping to identify key opportunities for energy savings – Providing comparison information to determine which approaches are most effective

Reducing Energy in an Office Building: Additional Engagement Actions • Additional CBSM and EIS tools that could be employed – Further barrier removal (more light switches) – Commitment – pledges to support target – Long-term prompting – Setting new norms to support persistence of savings – Incentives and disincentives
