The Built Environment Sustainability Scorecard (BESS) assessment tool for new projects was developed by the Council Alliance for a Sustainable Built Environment (CASBE).

The BESS tool provides an objective performance based analysis of nine key sustainable building design categories at the planning permit stage of the building lifecycle.

BESS is widely regarded as an appropriate sustainability assessment tool for both residential and non-residential development projects. Since its launch, several Victorian councils including Banyule, Bass Coast, Darebin, Dandenong, Hobsons Bay, Kingston, Knox, Manningham, Maroondah, Moonee Valley, Maribyrnong, Moreland, Port Phillip, Stonnington, Whitehorse, Whittlesea, Wyndham and Yarra have adopted BESS.

The BESS tool builds on the NCC energy efficiency measures and provides a framework for assessing building performance outcomes in relation to:

• Management

• Water

• Energy

• Stormwater

• Indoor Environment Quality

• Transport

• Waste

• Urban Ecology

• Innovation

BESS scores for the development are summarised in the following table.

6. 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 occupation.

In terms of performance outcomes, the development energy rating achieved exceeds the NCC 2016 energy efficiency requirements for Class 2 dwellings. However, the Class 1 dwellings do not achieve the minimum 6 star energy rating required. The design of Units 1 and 2 will need to be amended during detailed design in order to ensure the development complies with the NCC energy efficiency requirements

The combination of design features and services initiatives integrated into the proposed development meets water, energy, stormwater and indoor environment quality standards of the BESS assessment tool developed by CASBE and adopted by several Victorian Local Government Authorities including the City of Yarra.

The proposed development also achieves a Best Practice standard for urban stormwater quality and therefore achieves the objectives set out in Clause 22.16: Stormwater Management (WSUD) Policy of the Yarra Planning Scheme.

Accordingly, the sustainable design outcomes from the proposed development are considered to be adequate for a residential development of this scale.

Appendix 5: WSUD Maintenance Manual Rainwater Harvesting System Maintenance Program

Once installed, a systematic maintenance program will be implemented 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 Commission'. A schematic diagram of the rainwater tank installation is provided below.

Appendix 6: Site Management Plan During construction phase, the key pollutants at risk of entering the stormwater system include:

• Sediments (soil, sand, gravel and concrete washings); and

• Litter, debris etc.

These pollutants are as a result of several factors such as dirt from construction vehicles, stockpiles close to surface runoff flow paths, surface runoff from disturbed areas during earthmoving and construction works. It is therefore important to have measure that either prevent or minimise the pollutant loads entering stormwater system during construction.

In order to mitigate the impacts of the above pollutants on the stormwater system, the following stormwater management strategies will be implemented during the construction phase:

• Installation of onsite erosion and sediment control measures. All installed control measures shall be regularly inspected & maintained to ensure their effectiveness. Such measures may include (but not limited to):

o Silt fences

o sediment traps

o hay bales

o geotextile fabrics

• Where possible, litter bins with a lid will be used in order to prevent litter from getting blown away and potentially entering stormwater drains.

Additionally, the following work practices shall be adopted in order to reduce stormwater pollution:

• Site induction by the head contractor/ builder to make personnel aware of stormwater management measures in place

• Employ suitable measures to reduce mud being carried off-site into the roadways such as installing a rumble grid/ gravel/ crushed-rock driveway (or equivalent measure) to provide clean access for delivery vehicles, removing mud from vehicle tyres with a shovel etc.

• Safe handling and storage of chemicals, paints, oils and other elements that could wash off site to prevent them from entering stormwater drains.

• Where practicable, stockpiles will be covered, located within the site's fence and away from the lowest point of the site where surface runoff will drain to. This initiative will minimise erosion.

Accordingly, the measures presented above are considered appropriate for the proposed development at this stage of the project. The measures will reduce the pollutants entering stormwater system from the site during construction works thereby protecting waterways.

Furthermore, the initiatives are consistent with the Application Requirements set out in clause 22.16 of the City of Yarra Planning Scheme.
