NABERS

ENERGY

NABERS Energy assists owners and tenants to reduce energy use, reduce energy costs and reduce greenhouse emissions. It benchmarks a building's operational greenhouse impacts on a scale of one to five - one star being the most polluting and five stars the least, with half star increments.

The scope of NABERS Energy covers Tenancies, Base Buildings or Whole Buildings as defined below:

Tenancies - Light and power requirements for tenants occupying space in buildings where central services are supplied by the building.

Base buildings - Building central services including (but not limited to):

  • Air conditioning
  • Common area lighting
  • Lifts

Whole buildings - A combination of Base Building and Tenancy energy consumption.  Whole building operation energy including HVAC, lighting, equipment and sometimes tenancy fitouts.

WATER

NABERS Water measures the operational water consumption of a building on a scale of one to five stars with half star increments, reflecting the performance of the building relative to the market, from least efficient (one star) to best practice (five stars). Two and a half stars is the current market average.

5 Stars - Best building performance

The building is leading the market in water efficiency due to integrated design, operation, management and water efficiency.

4 Stars - Strong performance

The building demonstrates excellent water performance due to design and management practices, and high efficiency systems and equipment.

3 Stars - Above average performance

The building is performing better than the current market average.  Water efficiency is a priority in this building.  There are still opportunities for reducing water consumption.

2 Stars - Below average building performance

The building is below current market average performance.  There are opportunities that can be implemented to reduce water consumption, operating costs and the burden on our water supplies.

1 Star - Poor water management or systems

The building is consuming a lot of unnecessary water.  There are significant opportunities that can be implemented to reduce water consumption, operating costs and the burden on our water supplies.Bottom of Form

INDOOR ENVIRONMENT

The NABERS Indoor Environment rating for buildings is a measured in place environmental quality assessment and allows building owners and users to compare the indoor environment performance of your building to other similar buildings.

NABERS ratings can be used to rate tenancies, the base building or the whole building:

  • Tenancy Tenant's control of the indoor environment within the tenanted space, including the air quality, acoustic comfort, lighting and the office layout. The rating includes quantitative measurements and an occupant survey.
  • Base Building Central services and common areas of a building under the control of building management including thermal comfort, air quality and acoustic comfort. The rating includes only quantitative measurements.
  • Whole Building A combination of the above where the tenant is the owner and/or has control of the base building and tenancy performance.

WASTE

The NABERS Waste rating for buildings allows building owners and users to compare the waste generation and recycling performance of the building to other similar buildings.

A NABERS Waste accredited rating can be applied to three distinct and different situations:

  • Tenancy Covers the mass of total materials generated in spaces within a building occupied by a single tenant and under the control of that tenant. This includes garbage, recycling, and other specialised recycling paths (e.g. toxics, fluorescent tubes, secure recycling, etc). A Tenancy rating also considers the recycling efforts of tenants, by rating its recovery of recyclable materials.
  • Base Building Covers the recycling rate of all office spaces within a building and measures parameters that are under the control of the landlord or base building (ensuring that, for example, the recycling separated by tenants is being managed appropriately - i.e. recyclable materials leaving the dock in their appropriate recycling processing streams).
  • Whole Building Essentially a combination of the above. Covers the mass of total waste generated by the building and all of its office tenants, and the recycling rate of the buildings waste and recycling infrastructure where the tenant is the owner and/or has control of all services, or the building owner/manager are working in conjunction with all their tenants.
