Green building in South Africa is overseen by The Green Building Council of South Africa (launched 2007) which has developed Green Star SA rating tools, based on those developed by the Green Building Council of Australia tools, to provide the property industry with an objective measurement for green buildings and to recognize and reward environmental leadership in the property industry. Each Green Star SA rating tool reflects a different market sector (e.g. office, retail, multi-unit residential, etc.). The first tool developed was Green Star SA - Office which was published in pilot form for public comment in July 2008, with final version 1 release at the Green Building Council of South Africa Convention & Exhibition ’08 on 2–4 November 2008.
