Part 1

This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 55,103.17 MMBtu 46,970.59 MMBtu
Electricity from on-site renewables 36.17 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) 599,736 MMBtu 114,113.98 MMBtu
Total 654,875.34 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 July 1, 2018 June 30, 2019
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 3,522,880 Gross square feet 3,767,084 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 0.19 MMBtu per square foot 0.04 MMBtu per square foot
Source energy 0.22 MMBtu per square foot 0.07 MMBtu per square foot

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
0

Part 2 

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 5,451 Degree-Days (°F)
Cooling degree days 916 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 66,995 Square feet
Healthcare space 4,253 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
3,730,897 Gross square feet

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

Optional Fields 

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.
