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.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 144,477,938.66 Kilowatt-hours 492,958.73 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 61,910.11 Kilowatt-hours 211.24 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 21,365.98 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
514,535.94 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
737,449 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period July 1, 2010 June 30, 2011

A brief description of when and why the energy consumption baseline was adopted:

Baseline year 0.70 MMBtu per square meter 1.70 MMBtu per square meter

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
4.82

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
UQ is committed to reducing its energy consumption through a number of ongoing projects and initiatives, including our solar-powered electric vehicle fast-charging stations, our lighting retrofit program, our Energy Efficiency Project Fund and more.
Savings from the reduced power bills these projects help us achieve facilitate valuable ongoing research, allowing us to continue finding new and innovative ways to reduce our energy consumption and carbon emissions.

Energy efficiency is a core element of UQ's Green Office, Green Labs, Green the Team and Green Residents programs. For more information on these engagement programs, see the following online program pages, particularly the environmental surveys and aseessments performed within the Green Office and Green Labs programs.

A brief description of energy use standards and controls employed by the institution:
UQ's design guides mandates LED lighting with sensors. A comprehensive Building Management System (BMS) guide exists for detailing how HVAC is controlled including relevant set points etc.
More information on UQ's HVAC program can be found online:
https://sustainability.uq.edu.au/projects/energy-efficiency/uq-energy-efficient-hvac-program

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
UQ's energy efficient lighting program has seen more than 35,000 light fittings retrofitted since 2011. In addition motion sensors are standard requirements in all new buildings and building refurbishments. Motion sensor lighting has also been retrofitted in over a dozen existing buildings. Information is available online at:
https://sustainability.uq.edu.au/projects/energy-efficiency/lighting-retrofit-program

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
---

A brief description of co-generation employed by the institution:
UQ currently generates 6.3MW of solar PV from behind the meter (within the institution's boundaries). Cogeneration is not currently employed.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Over A$10 million has been spent in the 2015 to 2019 period on energy efficiency upgrades and retrofits, including fans, pumps, chillers, air handlers, recommissioning etc
