A brief description of when and why the building energy consumption baseline was adopted:
The energy consumption baseline was adopted in 2009 because this is the year when IU opened its Office of Sustainability.
None
A brief description of any building temperature standards employed by the institution:
Indiana University Bloomington uses timers through their Energy Management System to reset temperature settings in the majority of buildings on campus during unoccupied hours. This is 68 degrees in the winter and 76 degrees in the summer.
None

Physical Plant teams have been performing work within campus buildings for last 4 years to retrofit the buildings.
None
A brief description of any energy metering and management systems employed by the institution:
Indiana University Bloomington uses both Johnson Controls and Siemens building technology, as well as maintains a staffed 24 hour/day 365 days/year Control Center. All major energy and utility sources metered at all major campus buildings with remote reading technology.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
Campus Division (steward of the IUB landscape) has reduced irrigation on the campus interior, reduced mowing on the campus perimeter, and have begun to implement storm water management best practices in all new construction, and are beginning to introduce rain gardens. Organic waste has long been composted, but changes are being made to further utilize compost in the planting of campus landscape beds.
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
There was not been a campus-wide roll-off, but IUB has worked with Coca Cola's machine technicians to make programming changes to existing vending machines for energy conservation research.
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
Indiana University Bloomington is home to the largest single-campus energy and water competition in the nation, and is held twice annually. To date, Energy Challenge has saved over 11.8 million kWh of electricity (enough to take 11,756 homes offline during the competition), 28.6 million gallons of water (or 30 Olympic pools), and $2 million.
