Metric used in scoring for Part 1

Total site energy consumption per unit of EUI-adjusted floor area per degree day, performance year:

16.82 Btu / GSF / Degree-Day (°F)

Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	233,462,778 Kilowatt-hours	796,575.00 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	56,508 Kilowatt-hours	192.81 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	524,099 MMBtu
Imported steam, hot water, and/or chilled water	613,390 MMBtu

Total site energy consumption, baseline year:

1,934,256.80 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

12,709,312 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	July 1, 2014	June 30, 2015

A brief description of when and why the energy consumption baseline was adopted:

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.

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.15 MMBtu per square foot	0.27 MMBtu per square foot
Baseline year	0.15 MMBtu per square foot	0.29 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

7.15

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

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:

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
Taylor

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.

In order to reduce energy use and the carbon footprint at IUPUI, the campus has instituted set points for heating and cooling. In spring and summer, the cooling set point is 76 degrees. In fall and winter, the heating set point is 70 degrees.

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:

None used - utility dependent.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

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.
