What is “Behavior Change” at MIT?
Empowering individuals to take charge and affect change in their own “place” by bucking the prevailing system

Can you spot the labs?

Did we leave out the human aspect? Can we make better use of the VAV by
supplementing with behavior change? Collaboration: Sustainability Program,
MITEI, EHS, Chemistry, students, faculty and staff
Information: energy map, thesis e-mail from “The Boss” new fume hood training developed
Monitoring: average sash position by PI
Feedback: Monthly performance data

What have we learned?
Feedback can induce behavior change But must supplement other measures Behavior change can lead to cycle of
institutional change Challenge rules of thumb Retrofits (100-80 fpm) Integrated building HVAC audits &
decommissioning New construction design
Measurement and verification of results have growing importance Eco-Rep motivation MIT Efficiency Forward $$
