A brief description of when and why the building energy consumption baseline was adopted:

The building energy consumption baseline was adopted in alignment with our sustainability plan.


A brief description of any building temperature standards employed by the institution:

AU has a sophisticated Building Automation System (BAS) program which controls temperatures. For example, it includes temperature controls for night time set backs when building spaces are not occupied to ensure energy conservation.


A brief description of any light emitting diode (LED) lighting employed by the institution:

LED (Light-Emitting-Diode) lights were installed in the School of International Service parking garage and in the street lamps that light pathways on campus. Vending machines on campus were upgraded in 2010 with LED lighting.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Many campus offices, classrooms, and hallways have motion sensors.


A brief description of any passive solar heating employed by the institution:

The School of International Service (SIS) building features a passive solar air heating system.


A brief description of any ground-source heat pumps employed by the institution:
---

A brief description of any cogeneration technologies employed by the institution:
---

A brief description of any building recommissioning or retrofit program employed by the institution:
---

A brief description of any energy metering and management systems employed by the institution:

AU operates a computer-based Building Automation System that monitors and optimizes building control subsystems, including heating, cooling, ventilation, equipment scheduling, and alarm reporting. For example, when a room's temperature goes outside an established range, the energy management system alerts a facilities operator to the condition, who then responds by dispatching a technician to the site to address the problem.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
---

A brief description of any energy-efficient landscape design initiatives employed by the institution:
---

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
---

A brief description of other energy conservation and efficiency initiatives employed by the institution:
