A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

Engagement initiatives in relation to energy efficiency conducted at the University of Tasmania include:
• Energy reduction challenges for University residences,
• Display of engagement posters and stickers
• Annual building level energy reporting in University screens and Sustainability website
• Holiday shutdown campaigns
• Green Impact staff engagement program


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.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

All new light installations (including replacements) are LED unless other lighting is required to fulfill the purpose of the room/space.
Movement sensors are installed in some areas.


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

Passive solar heating was considered for various Green Star buildings


A brief description of co-generation employed by the institution:

NA


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Where financially viable, high efficiency alternatives are installed in any HVAC replacement works
