Old star, green star

摘要

Office buildings constructed during the past five years are, in general, more energy efficient than older buildings. This is to be expected. Prior to the advent of the National Australian Built Environment Rating Scheme, NABERS, and the Green Building Council of Australia's Green Star rating scheme, it was difficult for developers to define an eco-efficiency objective for a new office development. Now architects and engineers have 'star' ratings to target, and the buildings they design often display attributes and operational performances that exceed those targets.
