Green building certification has become a baseline expectation for commercial real estate. But with multiple rating systems available — LEED (US-origin, globally adopted), BREEAM (UK-origin), IGBC (India), GSAS (Qatar/Gulf) — choosing the right certification requires strategic thinking.
The systems differ in emphasis. LEED weighs energy performance heavily and has strong international recognition. BREEAM is more prescriptive on specific measures and is favoured in European markets. IGBC adapts green building principles to Indian climate, materials, and regulatory context. GSAS is mandatory for government buildings in Qatar.
For developers, the choice depends on target tenants (multinational corporates often prefer LEED), market expectations (IGBC for domestic Indian projects), and regulatory requirements (GSAS in Qatar).
RSustain has delivered green building advisory across all four systems. Our approach starts with climate-responsive design — optimising building orientation, envelope performance, and passive cooling before layering on active systems. This reduces both capital cost and certification cost.
The next frontier is operational performance. A building certified as “Platinum” at design stage may underperform in operation if commissioning, maintenance, and occupant behaviour are not managed. Life-cycle performance, not design-stage certification, is the true measure of a green building.
