Global Sustainability Assessment System

Global Sustainability Assessment System (GSAS) is the first performance-based system in the Middle East and North Africa (MENA) region, 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 the consumption of resources while addressing the local needs and environmental conditions specific to the region. GSAS adopts an integrated lifecycle approach for the assessment of the built environment including the design, construction and operational phases.
