11.52 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	16,130,632 Kilowatt-hours	55,037.72 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	156,563 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

211,600.72 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

1,785,527 Gross square feet

Baseline period

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

	Start date	End date
Baseline period	Jan. 1, 2005	Dec. 31, 2005

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

The baseline was established in 2005 as part of a State Executive Order 145 for energy reduction goals.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.09 MMBtu per square foot	0.14 MMBtu per square foot
Baseline year	0.12 MMBtu per square foot	0.18 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:

20.61

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:

Winter occupied temperatures are controlled between 68 and 70 degrees, unoccupied temperatures are set at 65 degrees. Summer occupied temperatures are controlled between 76 and 78 degrees. Building HVAC systems are controlled on/off based on occupancy schedule for all campus buildings through the campus Energy Management Systems (EMS).

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

90% of the campus site lighting was changed to LED, including South Fork Suites, Prucha Hall, and Stratton Hall hallway lights, Parker and Grimm basement lights, MVF Barns lights, facility warehouse lights, and the University Center common area lighting. Also, all remodel projects now include LED lights.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

The Research Development Institute building and Ames Residential Suites' domestic water heating employs passive solar heating.

A brief description of co-generation employed by the institution:

---

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

When replacing air handlers, incorporate heat recovery systems into buildings that bring in a lot of fresh air.
