The Green Building Council South Africa (GBCSA) developed an interiors tool – a green building rating tool that addresses tenant interior fit outs across different market segments. Developed in response to a market need, the rating tool puts the decision to commit to environmental sustainability firmly in the tenants’ hands. “Tenants can now decide, independently of the building owner, whether they wish to comply with green building standards within their own office spaces,” explains Brian Wilkinson, CEO of GBCSA. Previously, the rating tool covered only base buildings and not interior fit outs. Research and case studies have found that green offices boost productivity and performance, and people who work in green offices also have 25% better functioning memory because of their access to views. A panel of industry experts was involved in the development of the new rating tool, and was facilitated through sponsorship from Standard Bank and Saint-Gobain.
