Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 746,037 MMBtu | 793,799 MMBtu |
| Electricity from on-site renewables | 197.83 MMBtu | 192.81 MMBtu |
| District steam/hot water (sourced from offsite) | 555,384 MMBtu | 567,870 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 584,567 MMBtu | 539,341 MMBtu |
| Total | 1,886,185.83 MMBtu | 1,901,202.81 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2017 | June 30, 2018 |
| Baseline Year | July 1, 2014 | June 30, 2015 |
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 baseline was adopted based on the data and technology availability, which allowed for direct comparison between the baseline and performance year with no alterations to sensors or data availability.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 12,121,613 Gross square feet | 12,709,312 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 | 0.16 MMBtu per square foot | 0.15 MMBtu per square foot |
| Source energy | 0.30 MMBtu per square foot | 0.29 MMBtu per square foot |
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 | 5,310 Degree-Days (°F) |
| Cooling degree days | 1,418 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 1,062,672 Square feet |
| Healthcare space | 75,497 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:

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 Energy Challenge is an annual campus-wide initiative to reduce energy consumption campus-wide. Individual buildings compete for who can reduce their energy usage the most through simple behavior modifications. The Challenge is accompanied by a campaign to promote energy saving modifications and actions. The winners of the challenge earn a celebration party and their name is listed in the Energy Challenge banner permanently hanging in the Campus Center.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
IUPUI has building automation systems (BAS) for HVAC systems in 14 buildings (see list below). These allow for setbacks through the Building Automation Services department to reduce flows and/or change temperature set-points during unoccupied times. Additionally, 10.80% of all light fixtures, 19% of all sinks, and 32% of toilets on campus are motion activated.
Buildings with BAS HVAC:
University Hall
Cavanaugh
Campus Center
Dental School
SELB
Fesler
Glick
Herron
Hine Hall
Long
Neuro
Rotary
Riley Research

Bi-level LED lights with photocell and occupancy sensors were installed in the Riverwalk, Sports Complex and University Hospital parking garages. They reduced energy use in the three garages a total of 58 percent, from 1,841,610 to 778,854 kilowatt-hours. IUPUI was awarded the "Exemplary High Education Sector Parking" at the International Facility Management Association's conference in Houston, Texas.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Approximately 21,221 light bulbs, or 22.5% of all campus light bulbs, are LED fixtures.
Bi-level LED lights with photocell and occupancy sensors were installed in the Riverwalk, Sports Complex and University Hospital parking garages.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
None used.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
None used - utility dependent.
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):
Per IU policy, Energy Star or EPEAT certified electronics and equipment must be purchased when a version exists on the market.
Buildings are on a rotating re-commissioning schedule.
