Qatar Sustainability Assessment System (QSAS) was developed by the T.C. Chan Center for Building Simulation and Energy Studies at the University of Pennsylvania in collaboration with and on behalf of the Gulf Organisation for Research and Development [GORD] for the state of Qatar. The primary objective of QSAS is to create a sustainable built environment that minimises ecological impact while addressing the specific regional needs and environment of Qatar.
QSAS rates projects based on the classification as Commercial, Core & Shell, Schools, Residential, Mosques,
Hotels, Light Industry, Sports, and Neighbourhoods, rating them for design, construction and operations phases. The measurements, calculations, simulations, scoring ranges, and weights change accordingly for each building type and project phase.
QSAS comprises of eight categories like Urban Connectivity [UC], Site [S], Energy [E], Water [W], Materials [M], Indoor Environment [IE], Cultural & Economic Value [CE], Management & Operations [MO] with each category comprising of related criteria to help in measurement.
The certification levels range from 1 star to 6 stars with a maximum cumulative score of 3. A project earning a cumulative score of less than 0 is denied certification.
