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 | 47,190,890 Kilowatt-hours | 161,015.32 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 92,122 Kilowatt-hours | 314.32 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):

A brief description of energy use standards and controls employed by the institution:
The University employs a range of common energy use measures to varying extents. It utilises time scheduling for HVAC and is largely centralised allowing for minimisation of operation in line with time scheduling of spaces.
Controls are a mixture of modern and older analogue, though the older analogue systems have had their thermal plant replaced with central controls including ambient setpoint adjustment.
The majority of teaching spaces utilise time scheduling and CO2 control to minimise energy use. The University has a standard brief for control of new systems which is gradually being applied to existing systems. The standard brief is aimed at demand based controls that respond to user requirements as opposed to simply providing spaces that meet setpoints regardless of the users.
