"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 127,934 MMBtu 169,021 MMBtu
Electricity from on-site renewables 682 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 183,080 MMBtu 221,220 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 145,783 MMBtu 121,798 MMBtu
Total 457,479 MMBtu 512,039 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2009 June 30, 2010

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

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


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 3,583,328 Gross square feet 3,274,716 Gross square feet

Source-site ratio for grid-purchased electricity:
3.14

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.13 MMBtu per square foot 0.16 MMBtu per square foot
Source energy 0.21 MMBtu per square foot 0.28 MMBtu per square foot

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
23.56

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 5,059 Degree-Days (°F)
Cooling degree days 1,337 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 81,090 Square feet
Healthcare space 26,922 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
4,290,879 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
16.67 Btu / GSF / Degree-Day (°F)

Documentation (e.g. spreadsheet or utility records) 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 (e.g. outreach and education efforts):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

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, e.g. combined heat and power (CHP):
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

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.
