Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 289,263.10 MMBtu | 285,668 MMBtu |
| Electricity from on-site renewables | 517 MMBtu | 0 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) | 257,981.60 MMBtu | 228,026 MMBtu |
| Total | 547,761.70 MMBtu | 513,694 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):
A baseline year of FY 07 was established with the original STARS submission based on availability of reliable historical data.
Gross floor area of building space:

Optional Fields
---
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):
Most academic and administration buildings have time-of-day schedules in the building automation systems. The schedules allow the air handlers to run only as necessary to maintain the building temperature between 60 and 80 degrees during unoccupied periods. During the holiday setback, most buildings are allowed to float between 55 degF and 85 degF.
In addition, for rooms without timers in residence halls that close over winter break, we manually set back each area for the extended break -- usually 3-4 weeks.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Approximately 75% of outdoor street lights and pedestrian lights have been converted to LED. Programs are in place to convert the remaining areas to LED in the near future. Additionally, LEDs have been installed in hard to access or specialty applications in the four new buildings brought online since 2013. They have been installed in our library atrium and several small test areas around campus. LEDs are our design standard for new construction and are being used as the primary lighting source in the five renovation and new construction projects underway.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The South Residence Hall domestic water heating is provided with steam to water heat exchangers with 500 gallons of storage capacity. Forty flat plate solar thermal panels provide domestic hot water to reduce the steam load; the system employs four 650-gallon storage tanks. Domestic hot water is heated to 140F and a thermostatic mixing valve blends city water to reduce the building hot water temperature to 120F. The system supplies approximately 60% of the domestic hot water to the building.
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):
Retro-commissioning and repairs/corrections have been made on Alumni Hall, Benson Hall, Tribble Hall, Reynolda Hall, Reynolds Library, Worrell and the Scales Fine Art Building.
