Zero Net Emission Policy
Retrofit Benefits
1200 Buildings program
Council policy – Zero Net by 2020
GHG emissions by sector for the City of Melbourne 2005-06 total emissions estimated at 6.43 million tonnes CO2-e
How will we get to zero net?
Decarbonising the energy supply
Target = 18% reduction CO2e- on 2020 BAU
Commercial sector
Target = 25% reduction CO2e- on 2020 BAU
> energy efficiency in the commercial building sector
1200 Buildings - goals
• Catalyse the retrofit 1200 commercial buildings
• 38% increase in energy efficiency
• Mitigate 383kt/year of CO2-e
• Reduce potable water use by 5 giga litres/year
Key challenges for retrofitting

4.
Access to finance
Split owner/tenant incentives
Grid connected cogeneration is difficult
Cost of planning
Why retrofit? Good for business
• Lower utility costs
“…buildings with a green
• Lower operational costs
rating command rental rates
• Reduce the risk of obsolescence
that are roughly two per cent
• Improved corporate reputation
• Limit/prevent environmental liabilities
• Satisfied tenants results in retention
• Increased access to capital

What are buildings signing up to?
1. Baseline Assessment
2. Retrofit Action Plan
3. Undertake Retrofit Works
4. Annual Update
Initial measure of energy and water consumption to provide a benchmark for later
comparison.
Includes a list of interventions, capital cost, payback, potential CO2-e
savings/NABERS increase.
Design, documentation and works. Duration depends on building occupancy rates,
availability of funds, level of upgrade.
Determine how buildings are tracking against retrofit plans and CoM’s Zero Net
and water targets?
5. Completion of Works
Re-assessment of building post completion of final works to quantify the extent of
savings.
6. Final Recognition
CoM’s opportunity to recognise and publicly acknowledge the building’s efficiency
improvements.
The benefits – tools and resources
• Linking to existing resources – PCA
Retrofitting Guide
• Developing new templates/tools as required
• Fact sheets
• Case studies
Location to public transport, excellent indoor air quality and thermal comfort,
and cutting edge IT and communications capabilities ranked as the top three
attributes in building selection for staff attraction and retention.

1200 Buildings – access to finance
The Victorian Government has amended the City of Melbourne Act to
enable Melbourne City Council to apply property charges to repay
loans made to building owners.
