Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 110,358.44 Metric tons of CO2 equivalent 132,117.40 Metric tons of CO2 equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date Sept. 1, 2020 Sept. 1, 2008
End date Aug. 31, 2021 Aug. 31, 2009

A brief description of when and why the GHG emissions baseline was adopted:
We chose fiscal year 2009 as our baseline year as this was our most accurately assessed analysis of the university's greenhouse gas emissions prior to the performance year.

Figures needed to determine “Weighted Campus Users”:
Performance year Baseline year
Number of students resident on-site 3,137 4,950
Number of employees resident on-site 0 0
Number of other individuals resident on-site 0 0
Total full-time equivalent student enrollment 39,021 29,630
Full-time equivalent of employees 3,558 4,623
Full-time equivalent of students enrolled exclusively in distance education 27,153 893
Weighted Campus Users 12,353.75 26,257.50

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:
Performance year Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user 8.93 Metric tons of CO2 equivalent 5.03 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:
0

Gross floor area of building space, performance year:
16,365,114 Gross square feet

Floor area of energy intensive building space, performance year:
Floor area
Laboratory space 1,714,964 Square feet
Healthcare space 64,972 Square feet

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

A brief description of the institution’s GHG emissions reduction initiatives:
UH has various initiatives that impact the reduction of Green House Gasses. At the top level, all buildings are required to be LEED silver certified or above. Facilities Planning is also rolling our an Energy Master Plan in addition to maintaining a campus tree inventory to ensure proper mitigation of any canopy loss.

Data source(s) and notes about the submission:
The data in this section are from a COVID year so they do not represent normal emission levels. Tree survey results: http://www.uh.edu/af-university-services/sustainability/campus-initiatives/path-to-platinum/university-of-houston-tree-report_final The significant difference in "Imported steam, hot water, and/or chilled water" reported between Baseline Year and Performance Year is due to the deactivation of the University of Houston Medical Center building. This building, being separate from UH's Central Plant, required the importing of steam, hot water, and chilled water while it was operational. Since Hurricane Harvey in 2019 the building sustained significant flood damage necessitating its closure and drop in needed steam, etc. The remaining reported MMBtu are still for this building but in a deactivated capacity. Additionally, Stationary fuels used on-site to generate electricity and/or thermal energy is drastically lowered from previous years due to these coming from generators that are used as part of a peak demand response program (I.E. the generators are turned on to reduce grid strain.). The mmbtu here are results from the generators being run monthly for maintenance and upkeep as opposed to full service.
