BASIX

BASIX or Building Sustainability Index is a scheme introduced by the government of New South Wales, Australia on 1 July 2004[1][2] to regulate the energy efficiency of residential buildings.

It offers an online assessment tool for rating the expected performance of any residential development in terms of water efficiency, thermal comfort and energy usage.

It aims to reduce water consumption and greenhouse gas emissions by 40% compared to pre-BASIX (2004) buildings.

In order to meet these expectations, many people install rainwater tanks and environmentally friendly, water saving spouts.
