Green Star is the rating system used most commonly during design to ensure that the building will be highly energy efficient. Most recently it incorporates a performance rating for the building (As-Built ratings). The higher the rating the greater the perceived value of the building.

Our Green Star services range from providing strategic advice and peer review through to full involvement in a project from initial concept, through detailed design and construction, taking responsibility of achieving both Design and As-Built ratings.
