Grid-purchased electricity 2,563,276 MMBtu 1,830,896 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 2,866,575 MMBtu 4,909,874 MMBtu
Total 5,429,851 MMBtu 6,740,770 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Sept. 1, 2018 Aug. 31, 2019
Baseline Year Sept. 1, 2001 Aug. 31, 2002

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

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.

Gross floor area of building space:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

Texas A&M has a long history of trying to shape the attitudes of faculty, staff and stusdents 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 (e.g. building temperature standards, occupancy and vacancy sensors):

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, e.g. combined heat and power (CHP):

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 (e.g. building re-commissioning or retrofit programs):

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.
