The Global Sustainability Assessment System (GSAS) is a performance-based system developed for rating green buildings and infrastructures. The primary objective of GSAS is to create a sustainable built environment that minimizes ecological impacts and reduces resource use, considering the specific needs and context of the Middle East and North Africa regions (MENA). The purpose of GSAS Design & Build Parks Scheme is to provide recommendations and guidance for the effective implementation of sustainability goals within park projects.

Tool Outcome

GSAS rating indicates the overall achievement of the project and is determined by summing up the individual scores of all criteria. GSAS Design & Build Park Scheme has six ratings based on number of stars ranging from 1 to 6.
