Total site energy consumption per unit of EUI-adjusted floor area per degree day, performance year:

58 Btu / GSM / Degree-Day (°C)

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.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	90,989,442.90 Kilowatt-hours	310,455.98 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	309,255 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

619,710.98 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

434,949.64 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	Sept. 1, 2004	Aug. 31, 2005

A brief description of when and why the energy consumption baseline was adopted:

2005 was adopted as the baseline because this is when the office of sustainability was able to get accurate data

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	1.13 MMBtu per square meter	2.30 MMBtu per square meter
Baseline year	1.42 MMBtu per square meter	2.95 MMBtu per square meter

Metric used in scoring for Part 2

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

22.02

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

Our Campus Master Plan has a guiding principle related to the Environment and Sustainability. Sustainability guidelines are included in most sections of the master plan including Landscaping and Space Design Guidelines. https://www.uta.edu/masterplan/ut_arlington_master_plan.pdf

UTA has a written Indoor Air Quality Management Program that is managed by our Environmental Health and Safety office and applies to all spaces. This policy covers HVAC systems, operation and maintenance, renovations and new construction, custodial services, pest control, housing and food services. https://www.uta.edu/campus-ops/ehs/occupational/docs/iaq-program.pdf

Facilities Management’s Design Guidelines for renovations and new construction incorporate sustainable requirements in them such as zeroscaping, energy efficiency above minimum code levels, sustainable space design, sustainable building materials and a requirement to investigate renewable energy sources and new energy efficiency idea’s.

All of the square footage listed is managed by an energy management program. Our Thermal Energy Plant which produces chilled water and steam for campus buildings is monitored real time by Utilivisor to maintain the plant at optimal efficiency. 95% of our campus building utilities are metered, data collected and analyzed by our Siemens Navigator system and reviewed by our energy manager regularly. The Siemens system has the ability to flag areas of HVAC operation that are not operating at optimal efficiency in real time.

A brief description of energy use standards and controls employed by the institution:

The campus utilitizes the Siemens Apogee Energy Management System, which is connected to nearly all buildings on campus to provide energy metering and management services. The Siemens Apogee Energy Management System provides automated, schedule-based temperature setback control to the majority of campus building HVAC systems, and several buildings on campus utilize dual-technology (PIR/Infrared and Ultrasonic) occupancy sensors to control area lighting.
Cooling setpoint: 72°F; Heating setpoint: 68°F

UtiliVisor software is installed to provide real-time analysis of our Energy Plant's systems. This software allows us to continually optimize our entire Plant to ensure all systems are as efficient as possible.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

UT Arlington continues to complete LED lighting retrofits during renovations, remodeling, and upgrades to campus facilities and parking lots. During FY21 UT Arlington replaced more than 1,175 T-8 lighting fixtures with LED fixtures in classrooms, offices, and hallways.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

None.

A brief description of co-generation employed by the institution:

None.
