MIT’s Sustainability Challenge MIT uses over 375 million gallons of water

annually Generates over 11,500,000 lbs of trash per year …and over 338,000 lbs of chemical waste per year Produces thousands of cu/ft of other regulated lab

waste 19% of MIT community drives to campus alone But 81% take the T, carpool, bike, walk, etc.

versus 24% nationally Of over 200 campus vehicles, less than 10 use

alternative fuel Feeding a community of over 10,000 Energy, energy, energy…

Setting the Stage at MIT 159 academic buildings 14.5 million sq feet space 154 urban acres in Cambridge, MA 20,000 person campus population Over 1,500 research labs District steam, chilled water & electricity Utilities purchased for FY11 $34M

$18M natural gas (30 M ccf  ) $10.5M electric (103 M kwh of 253 M kWh total) $0.4M oil (156 K gal) $5M water and sewer (499 ccf)

Building energy intensity Campus average 243 kbtu/sf/year Typical wet lab 770 kbtu/sf/yr Clean rooms 2300 kbtu/sf/yr Typical dorm 108kbtu/sf/yr

What is MIT Efficiency Forward?

Long-term partnership for promoting energy efficiency and conservation investments - seeking to develop new approach for state goals 3 year collaborative framework A 34 million kwh electricity reduction commitment (a 15% reduction) A mix of funding sources: MIT capital, NSTAR incentives, re-investment of savings $14 million of work estimate to save over $50 million A mix of:

New construction enhancements Existing building retrofits Behavior change measures

How are we going to reach our 34+m kWh goal?

Lighting 50%

HVAC 35%

New Construction 10%

Behavior Change 5%
