A brief description of when and why the energy consumption baseline was adopted:
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.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.13 MMBtu per square foot | 0.24 MMBtu per square foot |
| Baseline year | 0.11 MMBtu per square foot | 0.21 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of energy use standards and controls employed by the institution:
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:
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
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.
