A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

In 2017, the Office of Sustainability worked with Energy Management and Housing and Residence life to do an Energy Competition using Lucid software, and educate students about saving energy.

Additionally, every winter break, the University implements curtailment. All buildings are shut down and students, faculty, and staff are instructed to turn off and unplug appliances, close windows, etc.


A brief description of energy use standards and controls 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. The Energy and Engineering Team also uses MeteoViva software, which determines a building's future needs for heating and cooling to reduce its energy costs. The software incorporates data from a building's heating and cooling usage and needs, and calculates the optimal settings for its Heating Ventilation Air Conditioning (HVAC) systems.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies 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.

See the LED Lighting section of the University's Design and Construction Standards: https://www.american.edu/finance/facilities/upload/26-55-22-led-lighting.pdf

LED fixtures with a Design Lights Consortium (DLC) listing, a U.S. Department of Energy (DOE) “LED Lighting Facts” label or a U.S. Environmental Protection Agency (EPA) ENERGY STAR label, which have demonstrated third-party testing verification.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

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


A brief description of co-generation employed by the institution:
---

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

As part of the University Design Standards, "Energy Star rated equipment is required for commercial dishwashers, fryers, griddles, hot food holding cabinets, ice machines, ovens, refrigerators and freezers, and steam cookers as well as any other product category as ratings become available."

Additionally, many of the standard appliances for dorms and offices are Energy Star rated appliances.
