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

The “Engineered Solution” for energy conservation Variable Air Volume & Monitoring and Control Phoenix Control Valve Sash Position Sensor
The “Behavioral Solution” for energy conservation: Information, Monitoring & Feedback • 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
Current Before intervention Feedback intervention: average sash position

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 $$
