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 64,881,059 Kilowatt-hours 221,374.17 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 46,749 MMBtu
Imported steam, hot water, and/or chilled water 260,453 MMBtu

Total site energy consumption, baseline year:
528,576.17 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
6,125,641 Gross square feet

Baseline period

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

Baseline period Jan. 1, 2017 Dec. 31, 2017

A brief description of when and why the energy consumption baseline was adopted:
In 2018 the university published it's first Campus Sustainability Plan that established a baseline year (average data of 2013-2015). Due to change in leadership the data for how that was derived was lost, in 2021, an evaluation of the usefulness of that baseline year for tracking progress was completed. It was agreed that 2017 would be used as a new baseline for tracking progress due to availability, accuracy and usefulness of the data.

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 0.17 MMBtu per square foot
Baseline year 0.09 MMBtu per square foot 0.16 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:
0

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:
Colleges are asked to submit course schedules for over half of the academic buildings on campuses and we deploy lighting schedules to turn off lights in specific classrooms, labs or sections of buildings when no activity is happening.

A brief description of energy use standards and controls employed by the institution:
Timers and temperature controls are used in several buildings across campus. Some of the buildings on campus impose temperature restrictions which reduce excessive heating in winters and cooling in summers. In addition, certain buildings on campus are scaled back during the evening hours to reduce heating, cooling and lighting loads.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED technology has been used in a variety of applications on campus. LED lights are used in two parking garages on campus, one a new construction, and the other was a pilot retrofit project. LED lighting has been incorporated into the new Law School and Engineering Hall. Several outdoor area street lights have been retrofitted and are now using LED lamps. LEDs are used in one of the surface parking lots on campus. LEDs were also installed in the hallways of McCabe Residence Hall during a major retrofit.

Marquette University is a member of Cree Inc.’s LED Revolution.

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

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:
It is standard procedure to relamp with LED when needed. When needed and available, appliances, plumbing fixtures, HVAC and other large equipment are replaced with energy efficiency and Energy Star options.
