A brief description of when and why the energy consumption baseline was adopted:
The baseline year of FY02 represents the start of a long journey to reduce the energy consumption of the campus. It represents the last year before many of the changes were implemented to make our campus more sustainable through energy reduction. This baseline was used to inform our Sustainability Master Plan evergreen goal of achieving net-zero emissions by 2050.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.11 MMBtu per square foot | 0.22 MMBtu per square foot |
| Baseline year | 0.31 MMBtu per square foot | 0.40 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Texas A&M has a long history of trying to shape the attitudes of faculty, staff, and students attitudes. The Energy Stewardship program continues its outreach to educate the campus constituents about energy efficiency. The newly formed Energy Performance Improvement or EPI program takes the Energy Stewardship program to the next level by engaging and incentivizing building occupants to take action to reduce energy consumption. During the pilot phase, the program cost avoided over $500k during the 12 month pilot period. The program was a success and we have launched a full-scale initiative that will cost avoid an additional $1 million in its first year.
A brief description of energy use standards and controls employed by the institution:
Texas A&M University has adopted a cooling standard of 70 degrees F and a heating standard of 65 degrees F across the campus. More importantly, when buildings or space is not occupied, the standard automatically resets to the unoccupied standard of 85 for cooling and 50 for heating.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
During FY17, Texas A&M upgraded all high pressure sodium and lower efficiency metal halide exterior lighting fixtures to LED.
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:
Texas A&M University has installed a $73.25 million combined heat and power upgrade that will supply over 45 MW of highly efficient power and steam generation to serve the campus. This system replaces an existing CHP system and achieves efficiencies in excess of 80%.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The campus created the first Energy Stewardship program in FY11 and currently has a fully staffed team of 6 Energy Stewards and a Supervisor. This team is responsible for closely monitoring and managing the campus energy consumption on a daily basis. This team relies on the data from the campus' comprehensive metering system to measure the energy consumption of the buildings and to make changes when necessary.

Data source(s) and notes about the submission:
In previous STARS reporting, imported electricity was reported in mmBTU and the campus has historically applied a "Source Heat Rate" of 8,110 to convert to mmBTU. This most closely approximates the grid heat rate. The most recent report simply asked for kWh and uses a different heat rate which most closely approximates a site heat rate. This is what makes the data looking different this year as compare to previous.
