New energy efficiency measures will impact building

The work programme consists of four initiatives, which are:

• Higher thermal insulation performance requirements for new homes
• Making it easier to install solar water heating systems
• Improving lighting in commercial buildings
• Improving heating, ventilation and air systems in commercial buildings.

The proposed measures would involve changes to the Building Code and/or new Department of Building and Housing compliance documents.

Preliminary work by the Department indicates that building such an energy efficient home could cost an additional $3,000 to $5,000, but consumers would gain through lower power bills and increased capital value on their homes, Cosgrove said.

The government is also considering raising the design standards for hot water systems in new houses and commercial buildings.

A public discussion document is planned for November. The Government will consider the submissions and decisions on the proposed measures will be made by April 2007.
