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.


A brief description of energy use standards and controls employed by the institution:

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:

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:

As Duquesne University renovates buildings and rooms, they always install energy efficient appliances and equipment.
