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.


Source-site ratio for imported electricity:
3.14

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.13 MMBtu / GSF 0.29 MMBtu / GSF
Baseline year 0.09 MMBtu / GSF 0.28 MMBtu / GSF

Percentage reduction in total source energy consumption per unit of floor area from baseline:
0

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

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.


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:

LED lights installed in foyer of Durango Building; additional LED lights will be installed at Hemisfair Park Campus (covered walkways)
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.


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:

No CHP


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

Energy Star rated appliances are required.
