Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 208,100 Metric tons of CO2 equivalent 269,425 Metric tons of CO2 equivalent

Performance and baseline periods

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date Jan. 1, 2022 Jan. 1, 2016
End date Dec. 31, 2022 Dec. 31, 2016

A brief description of when and why the GHG emissions baseline was adopted:
We selected 2016 as the baseline year for GHG Emissions and many of the other credits to include OP 5 Building Energy Efficiency and OP 21 Water Usage. In 2016 our primary fuel source at the Virginia Tech Power Plant was equal with 50% coal and 50% natural gas, and Phase 1 of our Five-Year Energy Action Plan implementation was completed. Phase 1 focused on our top 10 “energy hogs.” By 2019 our primary fuel source at the Virginia Tech Power Plant was reversed to 80% natural gas and 20% coal. We use this baseline to show how far we've come.

Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:

Number of students resident on-site 9,775 9,433
Number of employees resident on-site 2 2
Number of other individuals resident on-site 0 0
Total full-time equivalent student enrollment 36,207.40 33,223
Full-time equivalent of employees 8,270.36 7,678
Full-time equivalent of students enrolled exclusively in distance education 747.82 1,010
Weighted Campus Users 35,241.71 32,277

Metrics used in scoring for Part 1

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:

Other energy intensive space 261,516 Square feet

EUI-adjusted floor area, performance year:
12,742,668 Gross square feet

Metric used in scoring for Part 2

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:
0.02 MtCO2e per square foot

A brief description of the institution’s GHG emissions reduction initiatives:
- The conversion from coal to natural gas as the primary fuel source in the Virginia Tech Power Plant.

- Major upgrades to our underground infrastructure to include upgrades to the chilled water lines.

- The Office of Energy Management within the Division of the Campus Planning, Infrastructure, and Facilities guides the operations of the university to achieve tangible reductions in energy consumption on campus through the development of various Demand Side Management (DSM) policies, initiatives and projects. DSM promotes energy efficiency by means of upgrading, retrofitting, and commissioning mechanical, lighting, building automations and electrical systems in university buildings.

- The Five –Year Energy Action Plan developed in 2015-2016 addresses the energy efficiency improvements with the 50 most energy-intensive buildings on campus (“Energy Hogs”).

- The Virginia Tech Climate Action Commitment requires all new construction projects and major renovations project pursue LEED Silver Certification or better.

- Smart meter and solar energy projects underway through Virginia Tech Electrical Service (VTES)
