2.92 / 6.00 |
Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 71,654.97 MMBtu | 46,970.59 MMBtu |
| Electricity from on-site renewables | 60.99 MMBtu | 60.99 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 121,131.03 MMBtu | 114,113.98 MMBtu |
| Total | 192,846.99 MMBtu | 161,145.56 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | Jan. 1, 2018 | Dec. 31, 2018 |
| Baseline Year | Jan. 1, 2012 | Dec. 31, 2012 |
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):
2012 was the year that solar panels were installed on a campus building and the campus co-generation plant came online.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 3,524,393 Gross Square Feet | 3,767,084 Gross Square Feet |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.05 MMBtu / GSF | 0.04 MMBtu / GSF |
| Source energy | 0.10 MMBtu / GSF | 0.07 MMBtu / GSF |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 5,627 Degree-Days (°F) |
| Cooling degree days | 863 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 66,995 Square Feet |
| Healthcare space | 1,401 Square Feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
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):
Duquesne University monitors building and room schedules to turn off lights and 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.
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, e.g. combined heat and power (CHP):
Duquesne University operates a co-generation plant on site which provides combined heat and power for approximately 75 percent of campus needs.
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):
As Duquesne University renovates buildings and rooms, they always install energy efficient appliances and equipment.
