CUNDALL Overview & Summary 1 Project Introduction This Sustainability Management Plan (SMP) has been prepared to assess the proposed design for the development at 12 Nexus Court in Mulgrave at the Town Planning stage. The proposed development consists of three levels of basement, a mix of tenancy and parking on the first and ground floors, 5 levels of parking and 4 levels of commercial office space.

This SMP will demonstrate the proposed development's preliminary design potential to achieve a 4-Star Green Star standard under the Green Star — Design and As Built v1.2 environmental rating tool. This SMP is prepared as a response to the City of Monash Planning Scheme Clause 22.13.

The strategies and initiatives needed to be adopted have been identified and integrated within the design response to meet the above performance measures.

The target credits and associated points within them under the Green Star — Design and As Built rating tool are detailed in Appendix A of this report.

Based on the proposed initiatives being adopted and integrated into the development the following can be concluded from the predicted performance:

• The "Potential to Achieve" credits achieve 45 points which is equivalent to a 4 Star or Australian Best Practice Green Star benchmark rating.

This SMP is based on the following information:

• City of Monash Planning Scheme:

o Clause 22.13 Environmentally Sustainable Development Policy

• Green Star — Design and As Built (v1.2) Submission Guidelines;

• Architectural town planning drawings prepared by Gray Puksand.

• Concept Stornnwater Management Strategy prepared by Northrop.

2.2 Indoor Environment Quality (IEQ)

The objectives of the development with regard to Indoor Environment Quality (IEQ) are to provide occupants with a generally pleasant and comfortable internal space whilst reducing or avoiding potentially detrimental health impacts.


• Sufficient outdoor air supply levels will be provided to ensure levels of indoor pollutants are maintained at acceptable levels.

• All sources of pollutants (car exhaust, printers, cooking) will be mechanically exhausted.

• The design and treatment of internal constructions, finishes and building services will ensure that best practice acoustic standards are met, including reverberation times and acoustic separation between rooms.

• Artificial lighting design will use LED lighting throughout and have a high CRI (>80) for all light fittings. The lighting design will meet all requirements for illuminance levels and uniformity as per AS1680.

• The open floor plate and facade glazing design will provide office spaces with good access to views.

• At least 95% of Paints, Adhesives, Sealants, Carpets to be low VOC.

• At least 95% of engineered wood to be low Formaldehyde or reused engineered wood.

• High quality thermal comfort will be achieved via HVAC system and facade glazing design strategies.

2.3 Energy

The project intends to reduce greenhouse gas emissions when compared to conventional design; reduce the peak energy demand; and reduce the operational demand for energy through efficient plant and appliances with good management.


• LED lighting to be used throughout and automatic lighting controls such as occupant detection or daylight adjustment to be provided (unless functionally inappropriate).

• High efficiency mechanical plant will be utilised. The mechanical services design will include energy efficiency initiatives such as variable speed drives.

• A 50kWp solar PV array will be installed on the upper roof level for renewable energy generation for base- building services.

• A building management and control system will be installed.


D19-532827

CUNDALL 2.4 Transport

The project aims to reduce dependency on car use; encourage public transport use; and encourage low / no emission alternatives such as walking, cycling, motorbikes / mopeds or carpooling.


• Bicycle parking and end-of trip facilities will be provided as follows:

o At least 54 secure bike racks for regular building occupants.

o At least 8 visitor bike spaces.

o At least 10 showers and change facilities.

o At least 65 lockers for staff use.

2.5 Water

The objectives of the project with regards to sustainable use of water resources are to reduce potable water use during operation; reduce sewer discharges and pressure on local infrastructure.


2.6 Materials



The project aims to minimize the environmental impact of materials selection using an approach that considers the lifecycle implications in relation to the following issues:

• Eco-preferred content;

• environmental impacts during product manufacture;

• Toxicity (e.g. PCB's, cadmium, lead); Recycled content;

• Forestry practices; and

• Environmental recognition and certification (e.g. GECA materials & products, FSC timber, etc.).

o 5 Star for taps The project specific design strategies within this category include:

o 4 Star for toilets • No endangered species or vulnerable ecological communities.

o 5 Star for urinals • Redevelopment of a previously developed site.

o 3 Star (< 7.5 L/min) for showers • Ecological value will be improved with the inclusion of vegetation in the landscape.

• Rainwater tanks with an effective storage capacity of 30,000L to capture rainwater from the uppermost roof area. Captured rainwater will be reused for sanitary flushing and on-site landscape irrigation.

• No water-based heat rejection system to be used for mechanical heat rejection.

• At least 80% of fire system test water will be recirculated or reused on-site.

2.8 Emissions

The project aims to minimize peak storm water flows, and avoid localised emissions (e.g. light, noise pollution and ozone depleting substances).


• The post-development 5-year ARI will not exceed the pre-development 5-year ARI.

• External lighting to be designed and selected so that it does not have an upward lighting ratio above 5%.

CUNDALL Appendix B: Stormwater Management Concept Strategy

A Stormwater Management Concept Strategy has been prepared by the civil consultant.

The performance of the proposed stormwater management strategy was assessed against these targets using the conceptual software MUSIC (Version 6). The MUSIC model was developed in accordance with the Melbourne Water MUSIC Guidelines. A schematic of the MUSIC model can be seen below in Figure 1. The results from the MUSIC model are presented in Table 1, which shows the proposed stormwater strategy meets target objectives outlined in the City of Monash's Planning Scheme.

Please refer to the Stormwater Management Concept Strategy document prepared by Northrop for more details.
