Green building is cost-effective

1. Upfront investment in green building makes properties more valuable, with an average expected increase in value of 4 percent. By virtue of lowered maintenance and energy costs the return on investment from green building is rapid: green retrofit projects are generally expected to pay for itself in just seven years. 3

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.

The original policy issued by The Science Council of Japan was in Japanese, and this English article summarises the policy that outlined a roadmap to realize a healthy low-carbon society. The aim of the policy is to build a low carbon footprint and high environmental performance. There are four parts as below: 

(1) Increasing motivation for new, healthy, low-carbon lifestyles and behavioral changes

Cities need to become ‘smarter’ if we are to save the planet. John Dora, editor of a special issue of ICE Engineering Sustainability journal on smart cities, says the ingenuity of civil engineers will be essential for their delivery.
