A brief description of when and why the energy consumption baseline was adopted:
The baseline was adopted as part of the baselining exercise for targets related to the University of Sydney Sustainability Strategy 2020. 2018/2019 was the most recent year without significant ecological or global health impacts.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0 MMBtu per square meter | 0 MMBtu per square meter |
| Baseline year | 0 MMBtu per square meter | 0 MMBtu per square meter |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The University of Sydney is committed to lowering is non-renewable energy reliance. The University participates in Earth Hour and raises awareness about the need to save energy and turn of lights. Turn of light stickers and posters are displayed throughout the University offices and teaching and common spaces.
Staff were reminded to turn off all devices, including AC units not centrally controlled, that would not be used during the University Christmas shutdown in 2019 and again when the University moved to a work from home basis due to COVID.
Our intranet for staff contains useful, practical information on how to reduce energy needs and how to report issues like lights/AC that won't turn off when needed.
The University's new Sustainability Strategy contains a number of initiatives and behaviour change campaigns to help the staff and student body to cut down on individual energy use. These will roll out in 2021.
A brief description of energy use standards and controls employed by the institution:
The University has 'Indoor Air Quality and Thermal Comfort Guidelines' which create a standard temperature for the University's various spaces. BMS systems in buildings with centralised management are set to specific summer temperatures - 22oC to 24oC - and winter temperatures - 19oC to 23oC.
The University also has 'out of hours' switches and buttons for teaching and common spaces that engage between 9pm and 7am. The buttons give 2 hours worth of AC and lighting per press.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The University incorporates electrical design specifications as per its Sustainability Framework for Buildings. This is applied to new builds and major refurbishments of buildings/areas. This includes the requirement for LED lights and out of hour switches. Lighting should also be rated as highly energy efficient.
The University is implementing a multi-year project to convert old, low efficiency lighting to LED lighting and installing motion sensors linked to BMS systems including lighting. This is currently focused on our biggest campus at Camperdown/Darlington but all campuses are included in scope.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The Sustainability Framework for Buildings - New buildings required passive design report and incorporate passive design features; including building orientation and solar / thermal assessment. Examples of this can be seen in buildings such as the Sydney Law School, where the law library was designed with reflective natural lighting which reduces the energy needed to light and heat the library during daytime hours.
