Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 951,002 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 | 955,523 MMBtu | 963,026.76 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2016 | June 30, 2017 |
| 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.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 17,232,144 Gross Square Feet | 14,357,569 Gross Square Feet |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.06 MMBtu / GSF | 0.07 MMBtu / GSF |
| Source energy | 0.17 MMBtu / GSF | 0.21 MMBtu / GSF |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 4,384.60 Degree-Days (°F) |
| Cooling degree days | 1,436.60 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 543,850 Square Feet |
| Healthcare space | 25,069 Square Feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
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):
The Office of Sustainability coordinates two energy challenge competitions each academic year, one in the spring and one in the fall. Both last between 3-4 weeks and pit similar buildings versus one another, with winners determined based on savings relative to their own baseline. The fall 2018 challenge included 66 buildings including residence halls, academic buildings, lab/academic buildings, administrative buildings, and athletics.

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):
