2. Our philosophy
The University of Melbourne is
committed to embedding
sustainability in all aspects of
its research, teaching and
campus operations.
It seeks to enhance the
experience of students and
staff through the provision of a
world class sustainable
campus environment.
3. Green Building Certification models
across the Globe
LEED - Leadership in Energy & Environmental Design
USGBC – U.S. Green Building Council
4. Green Building Certification models
across the Globe
BREEAM
- Building Research Establishment
Environmental Assessment
Methodology
• country-specific (European) and
international Schemes
• best practice in sustainable
building design, construction and
operation
• 1 to 5 Stars awarded
5. Green Building Certification models
across the Globe
GBCA – Green Building Council of Australia
Building rating tools
• Design & As Built (presently being combined)
• Sector-specific versions – Education, Healthcare,
Industrial, Office …
• Green Star – Performance
• assesses the operational performance of buildings
Green Star Communities
• Precinct-wide sustainability rating tool
• University of Melbourne is:
• a Gold Sponsor of tool development
• has a registered project in pilot phase
- main Parkville campus of 159 buildings over 66
hectares (163 acres)

• Design Brief
! Commitment to innovation
! Best available techniques in sustainable design, and for use of materials, energy, air
and water.
! Act as a laboratory for control, adjust and monitor environmental systems
! High level of occupant comfort
• Built Pedagogy
! Communicate ongoing research
• Aurecon Building Services
! Mechanically assisted natural ventilation
! Air tight construction (pressure tested)
! Modular services for each space (outside air thru heat recovery and facades)
! Large central atrium with under floor air distribution
! Completed a detailed Co/Tri-generation Study (not enough carbon reduction)
! Thermal Pile Ground source heat pump system serving small area
! Ground source system can operate in multiple modes, provides maximum research

13. Green Star Buildings
Design vs. Performance
Lessons learnt so far – Good Points
– Energy consumption & efficiency
better than older buildings => lower
emissions and energy cost
– Building fabric, façade, glazing and
insulation superior compared to older
buildings
– Water consumption efficiency better
than older buildings => lower water
cost
– Building technology such as Building
Management Systems and lighting
control systems provide valuable
facilities management tools
14. Green Star Buildings
Design vs. Performance
Lessons learnt so far – Challenges
– Innovative elements like Blackwater
treatment plants, cogeneration, chilled
beams and passive ventilation systems
can be problematic
– Higher maintenance costs to manage
the technology systems
– Design energy modelling targets
difficult to achieve
– Analysis of data from sub-metering of
electricity and water usage is resource
intensive

15. Opportunities for Collaboration
the Group of Eight
• Go8 – eight leading research-intensive universities in Australia
• Opportunities for collaboration
– Performance of 11 certified buildings across the Group
– Design rating category for Educational buildings
– Many Laboratory-focussed, energy-intensive buildings
• 11 certified buildings, 2008 – 2014
• Total 180,000 square metres Gross Floor Area
(1,937,500 sq ft)
• 3 other buildings to rating standard (not certified)
• 5 star & 6 star ratings
