11.99 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 39,090,882 Kilowatt-hours 133,378.09 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 115,701.10 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
249,079.19 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
2,050,476 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period May 1, 2015 April 30, 2016

A brief description of when and why the energy consumption baseline was adopted:
The energy baseline covers the University's Fiscal Year 2016. This year is significant as it is the last full year of data before the University embarked on a campus infrastructure project.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.09 MMBtu per square foot 0.20 MMBtu per square foot
Baseline year 0.12 MMBtu per square foot 0.25 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:
20.56

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:
In the 2021-2022 academic year, the University encouraged the campus community to shift attitudes around energy efficiency via well-placed stickers throughout campus. These stickers encouraged the campus community to turn off lights when not in use, take the stairs instead of the elevator, and to unplug devices when not in use.

A brief description of energy use standards and controls employed by the institution:
The University has a campus-wide building automation system. The BAS coupled with Direct Digital Controls allows buildings and spaces to be placed on schedules based on occupancy thereby saving energy.

Additionally, when new buildings are constructed, design teams incorporate the latest ASHRAE 90.1 standards into building energy designs.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
In the 2018-2019 school year, the Pryzbyla Center, Edward M. Crough Center for Architectural Studies, the athletic fields, the Franny Murray Court at DuFour Athletic Center, and Hannon Hall all had significant lighting upgrades.

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

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

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
When possible, the Catholic University of America uses ENERGY STAR appliances in a range of applications such as lighting, IT equipment, AV equipment, and kitchen appliances.
