• Ventilation is designed for superior air change effectiveness, according to ASHRAE F25-1997 and laminar flow patterns.
• 30% of the project's net lettable area (NLA) provides good daylight levels for building users.
• Glare from natural lighting is reduced through blinds and shading.
• Installed high frequency ballasts 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.
• 60% of the nominated area has direct line of site to outdoor environments.
• The temperature of the work space is comfortable, within Predicted Mean Vote levels of -0.5 to +0.5.
• Internal noise levels are minimised to improve occupant comfort from building services and outside entities.
• Volatile organic compounds are minimised in 95% of painted surfaces and all carpets, adhesives and sealants.
• A dedicated tenant exhaust riser is installed to remove indoor pollutants from printing and photocopy areas.

Energy

• The base building achieves at least a 5 Star NABERS (formerly ABGR) rating, with an additional 60% CO2 reduction.
• Sub-metering is installed for all substantive base building uses.
• Sub-metering is installed for all tenancies within the building.
• Lighting power densities are 2.0 W/m2 per 100 lux for 95% of the NLA.
• Individual switches are installed for enclosed spaces and zones in accessible locations.
• Energy systems installed reduce the demand on the grid by at least 25% during peak demand hours.

Transport

• 25% of the total parking spaces are specified and labelled for small car or motorbike use.

• 20% of all aggregate used is recycled aggregate, and more than 15% of cement is replaced with industrial waste product.
• 90% of all steel (by mass) contains a post-consumer recycled content greater than 50%.
• Alternative materials replace 60% (by cost) of total PVC costs.

Land Use & Ecology

• Site was previously developed.
• Development reduces environmental impact upon the site.

Emissions

• No refrigerants are used in this project.
• Refrigerants are to be contained, in conjunction with a leak detection system.
• Automatic refrigerant pump-down is installed to prevent refrigerants escaping the equipment and into the atmosphere.
• Stormwater is collected, filtered and distributed from the site in accordance with the Victorian EPA Best Practice Guidelines or ANZECC's Guidelines for Environmental Management for Urban Stormwater.
• Project outflow to the sewerage system from building occupants’ usage has been greatly reduced.
• All thermal insulation avoids the use of ozone-depleting substances in both manufacture and composition.
