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 | 140,003.36 MMBtu | 140,085.52 MMBtu |
| Electricity from on-site renewables | 0 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) | 206,969.54 MMBtu | 206,440.63 MMBtu |
| Total | 346,972.90 MMBtu | 346,526.15 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2018 | June 30, 2019 |
| Baseline Year | July 1, 2011 | June 30, 2012 |
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 baseline of FY12 was adopted because this is the earliest there is complete utility data that is not archived and this was prior to the campus' Central Steam Plant Upgrade which replaced the coal-fire boiler with gas-fired.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 3,019,409 Gross square feet | 3,040,356 Gross square feet |

3.14
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.11 MMBtu per square foot | 0.11 MMBtu per square foot |
| Source energy | 0.21 MMBtu per square foot | 0.21 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:

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):
Tennessee Tech offers personal Energy Efficiency Training.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
---
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
As a construction standard, TN Tech continues to install, & upgrade to, LED lighting across campus in both full-building renovation projects, single room renovations and in exterior walkway and parking lot lighting.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
---
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):
Being a state university, TN Tech must follow the State of Tennessee's High Performance Building Requirements for all renovations and new construction. The following is from this manual:
"EE2. Energy Efficient Purchasing Policy
EE2.1 Energy Star qualified appliances and equipment: In accordance with Tennessee Code Annotated section 12-3-905, purchase and install Energy Star qualified equipment for all Energy Star eligible equipment types including appliances, office equipment, electronics, and commercial food service
equipment."
TN Tech has installed workout equipment made by SportsArt, to harness the energy produced during workouts. Seven ellipticals, four recumbent bikes, and four upright bikes and treadmills have been added to our fitness center to feed directly back into the buildings power supply. This equipment will be moved into the new Fitness Center upon completion Spring 2020.
