Category Achievements

Management

• A Green Star Accredited Professional is a principle participant in the project team to provide advice on the Green Star aims and processes from design through to the delivery.
• Provided comprehensive pre-commissioning, commissioning and quality monitoring for all building services. The design team and contractor transferred the information and documentation to the building owner upon completion.
• Contracted for a minimum 12 month building tuning period after handover, including quarterly reviews, monthly monitoring and final re-commissioning.
• Appointed a commissioning agent independent of the design team and contractors.
• Provided a comprehensive, yet simple Building Users' Guide.
• The contractor is implemented a project-specific Environmental Management Plan (EMP) in accordance with Section 4 of the NSW Environmental Management System Guidelines during construction. The contractor also held ISO14001 accreditation applicable to the construction works of the building.
• 80% of construction waste (by weight) re-used or recycled.

Indoor Environment Quality

• Naturally Ventilated (at least 90% of NLA)
• Internal noise levels are minimised.
• All carpets, adhesives and sealants and 95% of all painted surfaces are low in volatile organic compounds.
• All composite wood products have low-formaldehyde emissions.
• A dedicated tenant exhaust riser removes indoor pollutants from printing and photocopy areas.
• Ventilation is installed to achieve superior air change effectiveness, according to ASHRAE 129-1997 and laminar flow patterns.
• A carbon dioxide monitoring system is installed to track and adjust ventilation rates with low carbon dioxide levels upon occupancy.
• 30% of the project's net lettable area (NLA) provides good daylight levels for building users.
• High frequency ballasts are installed to reduce occupants' eye strain from low frequency flicker.
• Lighting levels are maintained at no more than 400 lux for 95% of the NLA at working plane.
• Naturally ventilated spaces have individual comfort control and fall within 90% of ASHRAE 55-2004 Acceptability Limit 1.

Energy

• The base building greenhouse gas emissions are projected to be less than 55 kgCO2/m2 per annum.
• Sub-metering is installed for all substantive building uses with an effective mechanism for monitoring data. Metering is separated for lighting/separate floors.
• Lighting power densities are 2.0 W/m2 per 100 lux for 95% of the NLA.
• Office lighting is installed in zones of not more than 100m2 and for all individual spaces, with switches in accessible locations. Additionally, an individually addressable lighting system is provided for 90% of NLA.

Transport

• The number of car parking spaces is at least 50% less than the maximum local planning allowances.
• A minimum of 80% of all preferred parking spaces are dedicated solely for use by car-pool participants, small cars, hybrid or other alternative fuel vehicles.
• A minimum of 10% or 10 parking spaces (whichever is greater) are designed and labelled for small vehicles and a minimum of 5% or 5 parking spaces (whichever is greater) are designed and labelled for mopeds and/or motorbikes.
• The project installed cyclist facilities, with secure bicycle storage for 10% of building staff and accessible shower and change facilities.
• Many public transport networks operate in close proximity with frequent peak hour services.

Water

• The projected use of potable water is representative of a 'best practice' scenario above standard building usage.
• Metering is installed for all major water uses, with an effective mechanism for monitoring consumption.
• Potable water consumption for landscape irrigation is reduced by 90%.
• Returns 80% of the water used for testing fire protection systems and drain-down water from sprinkler systems to temporary storage for reuse. Each floor is fitted with a sprinkler system has isolation valves or shut-off points for floor-by-floor testing.

Materials

• A dedicated storage area for separation and collection of recyclables is provided.
• 30% of the existing structure (by gross building volume) and 90% of the total building facade (by area) was re-used.
• 2% (or greater) of the project's total contract value is represented by reused products/materials.
• More than a 30% reduction in absolute quality of Portland cement across all concrete mixes.
• At least 95% of steel used in the building structure (structural steel and/or reinforcing steel) is sourced from a responsible steel maker
• Alternative materials replaced 60% (by cost) of total PVC costs.
• 95% of timber and composite timber products (by cost) used in the building and construction works was sourced from more sustainable means or are reused/recycled.
• 50% (by area) of the structural framing, roofing and facade cladding systems are designed for disassembly.

Land Use & Ecology

• 75% (or greater) of the site was previously developed.
• Development will reduce environmental impact upon the site.

Emissions

• All HVAC refrigerants have an Ozone Depleting Potential (ODP) of zero.
• Refrigerants are contained, in conjunction with a leak detection system. In addition, automatic refrigerant pump-down is installed to prevent refrigerants escaping the equipment and into the atmosphere.
• All thermal insulation avoids the use of ozone-depleting substances in both manufacture and composition.
• Predicted project outflow to the sewerage system from building occupants’ usage has been reduced more than 50% compared to an average-practice benchmark.
• Exterior lighting complies with AS4282 and does not direct any light beams into the night sky or beyond site boundaries. At least 95% of outdoor spaces do not exceed the minimum requirements of AS1158 for illuminance levels.
