Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 115,894,505 Kilowatt-hours | 395,432.05 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 427,000 Kilowatt-hours | 1,456.92 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 271,208 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
In February 2001 UT System created the EUTF (Energy Utility Task Force) that was subsequently charged with reducing energy consumption, lowering energy-related maintenance and operation costs, managing price commodity risk, and leveraging the System’s commodity purchasing power. The EUTF identified the year 2001 as the baseline year for this System-wide conservation effort.

| Performance year | 0.12 MMBtu per square foot | 0.27 MMBtu per square foot |
| Baseline year | 0.12 MMBtu per square foot | 0.28 MMBtu per square foot |

A brief description of energy use standards and controls employed by the institution:
Approximately 95% of buildings at UTSA are controlled by Siemens Building Automation System allowing for monitoring/control of electrical/mechanical systems; occupied/unoccupied settings adjust systems according to expected building occupancy loads; when buildings are known to be vacant systems are shutoff all together.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Buildings built after 2020 are 100% LED.
UT system has a policy to replace all lighting with LED. parking lot retrofits and building retrofits are occurring all over the cmapus. In 2019 university replaced lighting in the tunnel from sodium vapor running 24/7 to LED on motion sensors.
