Net zero energy building (NZEB) standards have been gaining prominence lately as the next performance target for buildings. However, despite the demonstrated benefits of such building performance across triple bottom-line concepts, Australia is yet to formulate a policy toward adopting a net zero energy building standard.

This chapter provides a review and critique of the development and current status of approaches to improve energy efficiency and broader sustainability in the Australian built environment. The focus is on the minimum building performance requirements set through the National Construction Code—Building Code of Australia, but the chapter also includes other mandatory and voluntary approaches which have been introduced over the past two decades.
