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 | 59,138,431 Kilowatt-hours | 201,780.33 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 6,778.35 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

| Baseline period | Sept. 1, 2006 | Aug. 31, 2007 |
A brief description of when and why the energy consumption baseline was adopted:
The baseline year was chosen because it preceeds a recent construction boom that has more than doubled the campus square footage with larger, modern, energy-efficient buildings.
Source energy

Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.10 MMBtu per square foot | 0.20 MMBtu per square foot |
| Baseline year | 0.08 MMBtu per square foot | 0.23 MMBtu per square foot |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
- Green Office Certification trains staff on how to change their workplace to be more energy efficient and sustainable
- Earth Week includes multiple events that teach students about sustainability and an Earth Fair for sustainability organizations and businesses
- AASHE Sustainability Month is held every October and catalyzes students to act through a variety of sustainability related events
- Earth Week includes multiple events that teach students about sustainability and an Earth Fair for sustainability organizations and businesses
- AASHE Sustainability Month is held every October and catalyzes students to act through a variety of sustainability related events
A brief description of energy use standards and controls employed by the institution:
Facilities Management maintains all HVAC systems at the set points of 74 in summer and 72 in winter. When it does not effect operations, HVAC systems are turned off at night. Approximately 60% of campus HVAC is turned off every night.
Construction standards for all new buildings at UT Dallas include occupancy sensors and LED exterior lighting.
Construction standards for all new buildings at UT Dallas include occupancy sensors and LED exterior lighting.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
UT Dallas is committed to energy conservation and transitioning away from high energy use lighting. Revolving Fund is utilized to fund LED retrofits throughout campus. The construction standards require LED’s for exterior lighting. The Research and Operations Center West and Bio engineering Science Building are LED only buildings.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The LEED Platinum Student Service Building utilizes a solar thermal hot water system.
A brief description of co-generation employed by the institution:
UT Dallas utilizes a 3.5 kW co-generation plant for power outages. Other than for planned and/or unplanned outages, the plant is not in daily operation.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
UT Dallas has 3-5 capital projects per year upgrading systems to more efficient alternatives. These projects are implemented by FM Building. Upgrades to constant volume HVAC systems are taking place to convert buildings to VAV with VFD. The Central Energy Plant is also being upgraded with a new chill water pump that will be higher efficiency.

Additional documentation to support the submission:
Data source(s) and notes about the submission:
FY2021 natural gas usage was significantly increased due to the February 2021 blackouts that occurred across the ERCOT grid. During this period, our Central Energy Plant was used to produce power for campus, as it does in case of all blackouts. The Central Energy Plant uses natural gas to produce this energy. This significantly increased our natural gas usage during FY2021 from the approximate 91,000 MMBtus used in FY2018.
