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

A brief description of any building temperature standards employed by the institution:
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 any light emitting diode (LED) lighting 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 any occupancy and/or vacancy sensors employed by the institution:
ASU uses only dual technology occupancy sensors (infrared or sound activated). These are being used to control lighting in the common areas (restrooms, lobbies, break rooms, copy rooms) of the following facilities: • Schaefer Center • Walker Hall • Peacock Hall • Physical Plant Administration • Physical Plant Motor Pool • Physical Plant Landscape Grounds Shop • Physical Plant Warehouse • Procurement Services • Thomas Hall • Kerr-Scott Hall • Varsity Gymnasium In addition, all of the lighting for the Reich College of Education is controlled by occupancy sensors. ASU is currently installing occupancy sensors in all of Peacock Hall and in the Plemmons Student Union that will control both lighting and HVAC. Many athletic facilities will be receiving occupancy sensors in the summer of 2015 as well.

A brief description of any passive solar heating employed by the institution:
None

A brief description of any ground-source heat pumps employed by the institution:
Water-to-water, ground source heat pumps are currently being installed at the Appalachian House.

A brief description of any cogeneration technologies employed by the institution:
None

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

A brief description of any energy metering and management systems employed by the institution:
Johnson Controls Metasys is installed in all or part of the following facilities: BB Dougherty Administration Beasley Media Complex Anne Belk Hall Belk Library University Bookstore College Street Chiller Plant Broyhill Music Building Canon Residence Hall Garland Hall Roess Dining Hall Appalachian House Chapel Wilson Hall Reich College of Education College of Education Annex Cone Residence Hall Holmes Convocation Center DD Dougherty Doughton Residence Hall Edwin Duncan Hall Schaefer Center Frank Residence Hall Hoey Residence Hall Human Resources John Thomas Hall Kerr-Scott Hall Kidd Brewer Stadium Living Learning Center Lovill Residence Hall Police and Parking Physical Plant Complex Plemmons Student Union University Data Center Procurement Services Peacock Hall Rankin Science Complex The Regional Utility Building Quinn Recreation Center Sanford Hall Smith-Wright Hall Student Recreation Center Miles Annas Summit Residence Hall Appalachian Hall Trivette Hall Turchin Visual Arts Center University Hall Varsity Gymnasium Walker Hall Wey Hall White Residence Hall

A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
ASU Purchasing Department has implemented a policy of purchasing only energy star appliances.

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:
ASU has eliminated the lighting load completely in 4 vending machines in one building at least.

A brief description of other energy conservation and efficiency initiatives employed by the institution:
In 2014 the institution deliberately scheduled a 2 week shut down over winter break to avoid heating buildings when only skeleton staff were reporting. Employees were required to use vacation days or provide community service during days that were scheduled as "work days" but during which time University buildings were not being heated. **Actual amount of savings will be available Jan 20, 2014*

Data source(s) and notes about 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.
