16.96 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	0.14 MMBtu per square foot	0.21 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:

27.43

Optional Fields

Documentation 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:

---

A brief description of energy use standards and controls employed by the institution:

In order to reduce energy use and our carbon footprint, IU 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:

---

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.
