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.
| kWh | MMBtu | |
| Imported electricity | 12,662,807 Kilowatt-hours | 43,205.50 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 | 622,713.02 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |
Total site energy consumption, baseline year:
Baseline year building space
Baseline period
| Start date | End date | |
| Baseline period | July 1, 2011 | June 30, 2012 |
A brief description of when and why the energy consumption baseline was adopted:
FY12 was the year that solar panels were installed on a campus building and the campus co-generation plant came online.
Source energy
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.24 MMBtu per square foot | 0.28 MMBtu per square foot |
| Baseline year | 0.18 MMBtu per square foot | 0.20 MMBtu per square foot |

Optional Fields
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
As a partner of the nation’s first EcoInnovation District, Duquesne University has committed to “creating an equitable and sustainable community." One of the goals of the EcoInnovation District involves reducing carbon emissions from energy use and as a result, Duquesne has a goal of achieving carbon neutrality. We are also a partner of the Pittsburgh 2030 District: Downtown. This is an internationally recognized, locally driven strategic initiative of Green Building Alliance (GBA) which aims to improve indoor air quality and reduce energy use, water consumption, and transportation emissions 50% by 2030.
A brief description of energy use standards and controls employed by the institution:
Duquesne University uses a direct digital control system to monitor rooms and turn off lights/lower temperatures when they are not in use automatically.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Duquesne University has installed LED bulbs in all of the campus street lights and ballasts. Additionally, as Duquesne University renovates buildings and rooms, they always install LED or other energy efficient lighting strategies. Duquesne University has also installed sodium vapor lighting in all on-campus parking garages. While students were away from campus during COVID-19, facilities management at Duquesne University replaced over 15,000 fluorescent lightbulbs on campus with LEDs.
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:
Duquesne has operated a combined heat and power (cogeneration) facility since 1997 that generates electricity and uses the waste heat from the process to heat and cool campus buildings. Annually, the natural gas-fired power plant produces approximately 75% of the power used for electricity and nearly 100% of the heating and cooling of the University's facilities. It is Pennsylvania's first approved generation system for creating Alternative Energy Credits. Duquesne purchases the remainder of its energy needs from renewable sources.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
As Duquesne University renovates buildings and rooms, they always install energy efficient appliances and equipment.

Additional documentation to support the submission:
Data source(s) and notes about the submission:
- Imported electricity value comes from electricity report that David Chismar sends for the GHG report
- Electricity from on-site, non-combustion facilities/devices refers to the amount of energy generated by the Des Places hall solar panel and is provided by David Chismar
- Stationary fuels used on-site to generate electricity and/or thermal energy comes from GHG checklist (Cogen MMBtu column of Scope 1b tab)
- To find heating and cooling degree days use the ENERGY STAR Portfolio Manager Degree Days calculator and use the postal code 15282. Make year ending June 30 of whatever fiscal year you are calculating for.
