Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 911,951.26 MMBtu | 963,026.76 MMBtu |
| Electricity from on-site renewables | 4,521 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 0 MMBtu | 0 MMBtu |
| Total | 916,472.26 MMBtu | 963,026.76 MMBtu |

| Baseline Year | July 1, 2009 | June 30, 2010 |
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
The energy consumption baseline was adopted in 2009 because this is the year when IU opened its Office of Sustainability.

Optional Fields
---
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
---
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
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.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LEDs installed total 1,291 fixtures, including:
Student Recreational Sports Center - 110 down lights
IU Alumni Center - 264 down lights
Rose Hall (residential)- 697 down lights
Ballantine Hall (academic) - 100 LED 2x4 fixtures
IU Health Center - 61 2x4 fixtures
Jordan Hall (academic) - 59 2x4 fixtures
Installations continue across campus and this number is continuing its climb.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Cyber-infrastructure Building (CIB) - http://sustain.indiana.edu/programs/green-building/green-building-projects/cyberinfrastructure-building.php
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
240 KW microturbine at Central Heating Plant replaced pressure reducing valves.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
