Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 281,491,396 Kilowatt-hours | 960,448.64 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 852,575 MMBtu |
| Imported steam, hot water, and/or chilled water | 18,079 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
To coincide with Arizona State University's first formal Greenhouse Gas inventory.

Data source(s) and notes about the submission:
Under "Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)," the 36,294,194 kWh represents electricity generated by ASU's 24 MW of on-campus solar. We do not retain the RECs for these systems. However, this electricity feeds directly into our campus buildings and as such does not suffer from transmission and distribution losses. Please note that this reported electricity for on-site systems is only that which is directly consumed by our campus buildings. Any electricity that was exported to the regional grid because instantaneous on-site generation exceeded instantaneous on-site demand was not included. Additionally, for GHG accounting purposes, this electricity is reported in OP-6 as a grid mix matched with Green-e RECs.
