"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 177,825.90 MMBtu 233,186.20 MMBtu
Electricity from on-site renewables 449.30 MMBtu 1.50 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) 449,940.10 MMBtu 667,694.40 MMBtu
Total 628,215.30 MMBtu 900,882.10 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2006 June 30, 2007

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):

In June 2007 a full-time Energy Manager was hired and subsequently kicked off ASU's first enery-reduction campaign in the following year (FY 2007-2008). Therefore, the year prior to the hiring of the Energy Manager (FY 2006-2007) before the first energy-reduction measures were implemented, is a logical baseline year.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 5,288,095 Gross Square Feet 4,382,856 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.12 MMBtu / GSF 0.21 MMBtu / GSF
Source energy 0.19 MMBtu / GSF 0.32 MMBtu / GSF

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

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 3,261 Degree-Days (°F)
Cooling degree days 1,036 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 258,954 Square Feet
Healthcare space 43,869 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
6,184,207 Gross Square Feet

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

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):

ASU utilizes a building automation system called Metasys by Johnson Controls Incorporated to schedule occupied and unoccupied modes of operation for several major buildings on campus.

The following standards are generally observed for most facilities:

Occupied heating setpoint 69°F
Occupied Cooling setpoint 74°F
Unoccupied heating setpoint 65°F
Unoccupied cooling setpoint 78°F

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

LEDs are used in both of ASU's major parking garages as well as in several other buildings including Katherine Harper-Kerr Scott, Farthing Auditorium, and John Thomas Hall.

All outdoor street lamps, post-top lamps, parking decks, and the Living Learning Center Residence Hall are currently LED.
-Belk Residence Hall is now being converted.
-The Plemmons Student Union, the Kidd Brewer Athletics Center and the Owens Field House, The Central Steam and Chiller Plants, the Roess Dining Hall, all softball and baseball facilities, the biology greenhouse, and the McKinney Alumni Center are currently under contract to be converted to all LED by summer of 2015.

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

The chancellor's residence is heated with geothermal wells as an indicator or leadership's commitment to sustainable energy. Kerr Scott (where design students are taught) was designed with passive solar.

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):

The Plemmons Student Union and the Garland Hall Science Facility (formerly known as CAP Science) have both been re-commissioned in the last five years. Deficiencies discovered during the re-commissioning process are currently being addressed including the installation of all new digital controls for both facilities.

Additional documentation to support the submission:

Note: Steam is produced on site and not purchased.

Note 2: Use of campus steam has decreased, despite the increase in square footage. This is due to improvements made in condensation recovery and building efficiencies.
