Total 316,968.89 MMBtu 307,930 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year May 1, 2016 April 30, 2017
Baseline Year May 1, 2005 April 30, 2006

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):

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


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 4,553,431.82 Gross Square Feet 3,009,254 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 0.07 MMBtu / GSF 0.10 MMBtu / GSF
Source energy 0.16 MMBtu / GSF 0.23 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
32.90

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 3,311 Degree-Days (°F)
Cooling degree days 1,908 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 107,561.57 Square Feet
Healthcare space 4,815 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
4,813,767.94 Gross Square Feet

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

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):

Lucid Energy Competition and working with housing and residence life to educate students about saving energy.


A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

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 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.


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, e.g. combined heat and power (CHP):
---

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):
