A brief description of the on-site renewable electricity generating facilities/devices:

While the University of Pittsburgh has a total of 3 on-site renewable installations in the university system, only 1 is within the boundary of this AASHE STARS report.

Benedum Hall boasts a 4.32 kW photovoltaic installation on its roof, which was installed in 2012. This photovoltaic (PV) array is for research purposes, including 18 solar PV panels at different tilts (25 degrees and 45 degrees) and positioned in 3 directions (East, South, and West). It produces ~4,000 kWh annually, which is tied in directly to the building.

A brief description of other sources of electricity not specified above:

The calculations above take the 2019 PJM fuel mix for the Pittsburgh region and layers in on-site solar PV production, while accounting for all directly procured energy and RECs as national wind.

The "other" category in this calculation includes the following sources (referenced with the % of the larger electricity grid they provide, not as Pitt's sources): 0.51% waste-to-energy, 0.30% captured methane, 0.1% oil, and 0.027% non-renewable fuel cells.

A brief description of other sources of building heating not specified above:

Most University of Pittsburgh facilities are heated by steam, which is generated by two cooperatively-owned district steam plants currently fueled by 100% natural gas. The plants are also capable of burning fuel oil, but only as a backup fuel source in case of emergencies. Buildings not heated by steam are heated by natural gas.

Some buildings also receive cooling via chilled water (which is produced on campus with electricity), but this question refers to heating only.
