Environmental assessment and sustainability

What type of legislation exists dealing with environmental issues affecting building works and with promoting sustainable developments?

Australia

Australia

Water

Water quality is protected by water-related State Acts and Regulations which control issues such as pollution, surface water, groundwater and discharge to sewers.

Waste

A wide range of duty-of-care legislation controls the generation, transportation and disposal of waste. Every business is legally obliged to ensure its waste is handled and disposed of safely. State environmental protection legislation requires that commercial construction projects have a site waste management plan, to be kept updated throughout the project.

Environmental impact assessments

Under state local planning legislation, a construction project likely to have significant effect on the environment by virtue of factors such as its nature, size or location may require an environmental impact assessment before planning permission is granted. There is also Commonwealth legislation (such as the Environmental Protection and Biodiversity Conservation Act) which regulates approvals required for projects which may have an impact on matters of national environmental significance.

Sustainable development

Energy-efficient buildings are becoming an increasing focus for the government, developers, investors, builders and prospective tenants.

A number of green rating schemes currently operate in Australia across a range of development types. The two most prominent are:

  1. The Green Star rating scheme operated by the Green Building Council of Australia (GBCA).
  2. The National Australian Built Environment Rating System administered nationally by the New South Wales Office of Environment and Heritage, on behalf of the Commonwealth, state and territory governments. (NABERS).

Green Star is a national and voluntary environmental rating scheme. The main categories of Green Star rating evaluate the environmental design of buildings at a conceptual stage and at an as-built stage. The Green Star Communities rating tool assesses the impact of operations on their local community. These rating tools assess a building or a development’s potential to reduce its environmental impact, rather than its operation.

The Green Star Performance rating tool, introduced in October 2013, measures the potential environmental impact of a building in relation to nine building element categories, namely management, indoor environment quality, energy use, transport, water use, land use and ecology, materials, emissions, and innovation in process and design. The Green Star Communities rating tool uses five categories governance, liveability, economic prosperity, environment and innovation.

NABERS is a national performance-based, voluntary rating system for existing buildings, tenancies and homes. It rates an existing building on the basis of its measured operational impacts on the environment.

NABERS has been adopted as the tool for assessing the energy efficiency of buildings for the Commercial Building Disclosure scheme which requires mandatory assessments prior to the leasing, subleasing or sale of commercial buildings of more than 2,000m2.

Construction projects may also be required to meet any sustainable development objectives contained within the relevant regional/area development plan.
