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.
• Contracted to provide comprehensive pre-commissioning, commissioning and quality monitoring for all building services. The design team and contractor are to transfer 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.
• Committed to provide a comprehensive, yet simple Building Users' Guide.
• The contractor is required to implement a project-specific Environmental Management Plan (EMP) in accordance with Section 4 of the NSW Environmental Management System Guidelines during construction. The contractor must also hold ISO14001 accreditation applicable to the construction works of the building.
• Committed to re-using or recycling 80% of construction waste (by weight).

Indoor Environment Quality

• Ventilation rates are designed for 50% improvement above the the fresh air rate requirements in AS 1668.2-2002.
• Internal noise levels are designed for minimisation.
• All carpets, adhesives and sealants and 95% of all painted surfaces are specified to be low in volatile organic compounds.
• All composite wood products specified have low-formaldehyde emissions.
• Designed ventilation systems will actively control humidity and minimise mould.
• A dedicated tenant exhaust riser is specified to remove indoor pollutants from printing and photocopy areas.
• Ventilation is designed for superior air change effectiveness, according to ASHRAE 129-1997 and laminar flow patterns.
• A carbon dioxide monitoring system is specified to track and adjust ventilation rates with low carbon dioxide levels upon occupancy.
• Daylight modelling shows that 30% of the project's net lettable area (NLA) provides good daylight levels for building users.
• Blinds and shading are components of the design, reducing glare from natural lighting.
• High frequency ballasts are to be included to reduce occupants' eye strain from low frequency flicker.
• Lighting levels are designed to be maintained at no more than 400 lux for 95% of the NLA at working plane.
• 60% of the nominated area is designed for direct line of site to outdoor environments.
• The mechanically air-counditioned work space is designed to be a comfortable temperature, within Predicted Mean Vote levels of -0.5 to +0.5.

Energy

• The base building greenhouse gas emissions are projected to be less than 40 kgCO2/m2 per annum.
• Sub-metering is to be installed for all substantive building uses with an effective mechanism for monitoring data. Metering is separated for lighting/separate floors.
• Lighting power densities are specified as 1.5 W/m2 per 100 lux for 95% of the NLA.
• Office lighting is designed for zones of not more than 100m2 and for all individual spaces, with switches in accessible locations. Additionally, an individually addressable lighting system is to be provided for 90% of NLA.
• Energy demand will be actively reduced by at least 30% during peak hours.

Transport

• Of the total parking on the site, 10% of parking is designed for small vehicles and 5% is designed for mopeds and/or motorbikes. Of all the preferred parking spaces, 80% are dedicated solely for car-pool participants, small cars, hybrids or other alternative fuel vehicles.
• The project is to include cyclist facilities, with secure bicycle storage for 5% 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 designed to be a leader in efficiency.
• Metering is specified for all major water uses, with an effective mechanism for monitoring consumption.
• Potable water consumption for landscape irrigation is designed to be reduced by 90%.
• Potable water consumption of water-based heat rejection systems is designed to be reduced by 90%.
• Designed to return 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 to be provided.
• The design of the building has reduced the total amount of material used compared to standard practice through a combination of structural, finishes and cladding, ducting and piping and layout efficiencies.
• Specified higher than 30% reduction in absolute quality of Portland cement across all concrete mixes. 20% of all structural mixes is recycled and no natural aggregates are used in non-structural uses.
• 90% of all steel (by mass) specified is reused or contains a post-consumer recycled content greater than 50%.
• Alternative materials are specified to replace 60% (by cost) of total PVC costs.
• 95% of specified timber and composite timber products (by cost) to be used in the building and construction works was sourced from more sustainable means or are reused/recycled.
• 95% of the total facade is designed for disassembly.

Land Use & Ecology

• 75% (or greater) of the site was previously developed.
• Site was contaminated before the project works and will be fully remediated prior to construction.
• Development will reduce environmental impact upon the site.

Emissions

• All specified HVAC refrigerants have an Ozone Depleting Potential (ODP) of zero.
• Refrigerants are to be contained, in conjunction with a leak detection system.
• All specified 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 30% compared to an average-practice benchmark. A Blackwater Treatment Plant will be installed with a minimum contract for maintenance of 5 years.
• Exterior lighting designs comply with AS4282 and do not direct any light beams into the night sky or beyond site boundaries. At least 95% of outdoor spaces are not to exceed the minimum requirements of AS1158 for illuminance levels.
• No water-based heat rejection systems to be included in the project.
