Energy-efficiency measures for commercial and public buildings will be introduced into the Building Code of Australia (BCA) 2006, from 1 May 2006. The changes will provide benefits to the environment through reduced greenhouse gas emissions and to owner/occupiers through reduced energy costs.

Why do we need energy-efficient commercial buildings?

The Australian Greenhouse Office projects that greenhouse gas emissions from the operation of commercial buildings will increase by a staggering 94 per cent during the period 1990-2010. The new energy-efficiency measures, expected to be included in the BCA 2006, form a key feature of the federal and state governments' commitment to reducing greenhouse gas emissions in Australia.

Which building will the measures apply to?

The requirements will apply to all classes of commercial and public buildings. It is important to note that the energy measures apply to buildings being refurbished, altered or extended as well as new buildings.

Commercial building classes include:

• Class 5 - Commercial office building                   
• Class 6 - Shop or other retail building
• Class 7 - Car park or wholesale goods facility     
• Class 8 - Laboratory or industrial building
• Class 9 - Public building: health care facility, school, assembly building.
