Diamond miner De Beers’ new rough diamond sorting, valuation and sales building Sky Park, in Johannesburg, has received a five-star interior green rating and two four-star green building ratings from the Green Building Council of South Africa (GBCSA). The ratings were awarded for the sustainable design elements proposed and approved by the GBCSA, as well as the ‘As-Build’ rating that evaluates the use of green and sustainable materials during the construction phase. The waste, water, and power management strategies implemented during construction were also recognised as part of these awards.
