Builders to test new energy-saving standards

The new standards will see more solar panels on homes

New sustainability standards for homes could save Central Coast residents up to $980 a year on energy bills and reduce the state’s carbon footprint.

Minister for Planning and Public Spaces, Rob Stokes, said a proposed raising of BASIX standards would see more energy efficient homes being built.

The Building Sustainability Index (BASIX) is a key assessment tool that ensures new homes are comfortable to live in regardless of the temperature, are more energy efficient and save water.

Stokes said BASIX had prevented 12.3 million tonnes of greenhouse gas over the past 17 years – equivalent to taking 2.5 million cars off the road.

“These proposed increases in standards will see more energy-efficient homes with better design, better insulation, more sunlight and more solar panels,” he said.

“We want to lift BASIX standards even higher to drive down emissions further, saving another 150,000 tonnes a year and helping to achieve net-zero emissions by 2050.

“Better design will keep your home naturally cooler in summer and warmer in winter, so you won’t be turning the heater or air conditioner on as often.”

Stokes said energy bills are expected to reduce significantly as a result of the new BASIX standards with savings of up to $190 each year for people living in high-rise apartments and saving of up to $980 a year for people living in new houses in the regions.

“To showcase the benefits of these new measures, we’re inviting up to 10 builders to test the proposed BASIX requirements ahead of its official roll out next year,” Stokes said.

The new targets complement work underway, such as planting one million trees and investing $4.8M to make building materials more environmentally friendly.
