20.03 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	282,247,312 Kilowatt-hours	963,027.83 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

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

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	2,799,162 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

3,762,189.83 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

15,889,707 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, 2009	June 30, 2010

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

The energy consumption baseline was adopted in 2009 because this is the year when IU opened its Office of Sustainability.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.14 MMBtu per square foot	0.24 MMBtu per square foot
Baseline year	0.24 MMBtu per square foot	0.36 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:

32.59

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

The Office of Sustainability coordinates two energy challenge competition in the fall every year. The challenge lasts 3-4 weeks and pits 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:

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:
