10. Conclusion
This report sets out a range of sustainable design features which are integrated into the design and specification
of the proposed development, in order to improve environmental outcomes during construction and occupation.
This report provides a detailed analysis of ESD performance outcomes utilising relevant ‘tools’ which are
referenced in the Port Phillip Environmentally Sustainable Development Policy.
In terms of performance outcomes, the analysis presented in this report demonstrates that the proposed
development can achieve a Green Star 5 Star Rating which is defined as Australian Excellence standard by
the Green Building Council of Australia
The analysis undertaken also confirms that the proposed development achieves a NatHERS energy rating 10%
above the applicable NCC standard and meets the Best Practice standard for Urban Stormwater Quality.
Accordingly, the sustainable design outcomes from the proposed development are considered to be appropriate
for a Build to Rent mixed-use development of this scale. The outcomes are also consistent with the objectives
of the Environmentally Sustainable Development Policy and the Water Sensitive Urban Design Policy set out
in Clause 22.12 and Clause 22.13 of the Port Phillip Planning Scheme.

NOTES
The energy rating software accredited by the Australian Building Codes Board contains a relatively limited
library of window systems. When the glazing systems specified are not available in the software, the protocol
requires that the glazing type which most closely matches the specified glazing is selected for the purpose of
calculating the energy rating.
The table above sets out the glazing specified on the architectural drawings together with the glazing input for
the purposes of calculating the energy rating.
The whole of window U – Value must be equal or lower than the energy rating software value and the whole
of window SHGC – Value must be within +/-5% of the energy rating software value.

Appendix 5: WSUD Maintenance Manual
Rainwater Harvesting System Maintenance Program
Once installed, a systematic maintenance program will be implemented by the owner’s corporation
maintenance contractor to ensure the rainwater harvesting system operates as designed and water quality is
maintained.
The scope of the maintenance program will include inspection and rectification of issues associated with:
• Roof gutters and downpipes
• First flush screens and filtration devices
• Pumps
• Distribution pipework and reticulation systems
• Overflow systems
Inspections of the system and any maintenance works required will be undertaken on a quarterly basis.
The rainwater harvesting system will be installed in accordance with the guidelines set out in the Rainwater
Design & Installation Handbook published by the National Water Commission3. A schematic diagram of the
rainwater tank installation is provided below.

Appendix 6: Solar Photovoltaic System
High-efficiency solar PV modules with a total capacity of 26 kWp will be installed at roof level as per the
preliminary layout indicated below.
Each PV module will be oriented northwards at 10-15° tilt and have at least 300Wp capacity (i.e. over 20% more efficient than traditional 250Wp 60-cell modules). High-efficiency modules deliver more compact arrays with inherently lower embodied ecological impact per unit of generation than standard efficiency modules.
Indicative Solar Photovoltaic array layout
Total yield of this array will be approximately 37 MWh per annum equating to an estimated annual carbon
emissions offset of 43 tonnes CO2-e per annum.
