15.13 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	49,537,366 Kilowatt-hours	169,021.49 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	121,798 MMBtu
Imported steam, hot water, and/or chilled water	221,220 MMBtu

Total site energy consumption, baseline year:

512,039.49 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

3,274,716 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:

Creighton's president signed the ACUPCC in January 2010; the first GHG inventory was completed that year.

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.12 MMBtu per square foot	0.18 MMBtu per square foot
Baseline year	0.16 MMBtu per square foot	0.27 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:

31.69

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

Creighton University has beenoptimizing energy management systems across the campus, replacing fluorescent lights with LED lighting in parking garages and buildings, retro-commissioning the business center to enhance energy efficiency, insulating piping and mechanical equipment to minimize heat loss, upgrading science labs to improve air conditioning, evaluating building operations and energy performance s for potential efficiency enhancements, implementing a Peak Energy Savings Program to reduce electricity demand and foster an energy conservation culture, replacing bio-safety cabinets with zero-exhaust models, upgrading chilled water valves for better flow control, and recommissioning HVAC and Building Controls at the Champion Center.

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

State of the art building management systems are used to control temperatures in building spaces/rooms during occupied and unoccupied hours. We have night set backs incorporated for the campus. We also have unoccupied modes set. We also employee a Demand control ventilation on all new installs to limit the amount of outside air that we need to recondition.

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

We have upgraded many of the existing lighting to LED's, including such applications as hallways, retail spaces and outdoor pathway lighting. We have a standard to install only new LED's for all project work. LEDs in the Energy Technology department's classroom are powered using a low-voltage transformer.

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

There is a passive solar heater on one of our buildings. Two of our buildings have geothermal systems. We also have a solar water heater on a building.

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:

We are working with the Control contractor on building HVAC commissioning.
We undertook a program to replace over a dozen ducted B2 biosafety cabinets with unducted C1 biosafety cabinets, drastically reducing the energy usage of these types of cabinets.

Facilities Management is working with labs to replace traditional -80 freezers with high performance stirling engine freezers.

An ongoing program is replacing steam traps with new, more efficient versions across campus.
