A brief description of when and why the energy consumption baseline was adopted:
We adopted 2005 as our baseline year for GHG emissions reductions to align with the baseline year set in the Paris Climate Agreement. This baseline was adopted alongside the adoption of our Campus Sustainability Plan in 2018. This is also the baseline year we are using for OP2.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:

Data source(s) and notes about the submission:
Data was provided by Facilities Management. Unit conversions were done in an internal tracking sheet using the calculations provided in the Campus Energy Consumption Converter. Degree days were pulled from DegreeDays.net.
Our gross square footage decreased from 2004 to 2020 because of the sale of several houses that were located on the periphery of our campus.
