LEED certification consultancy

Full-lifecycle LEED support

LEED certification is the most widely recognized green building standard in the world, with over 100,000 registered projects across 180 countries. ISG has been delivering LEED consultancy since our founding, building a practice that spans from early design integration through post-construction certification.

We do not treat LEED as a checklist exercise. Our consultants embed within the design team from day one, identifying credit opportunities that align with the project's architectural intent and budget reality. This approach consistently delivers certifications at or above the target level without late-stage cost surprises.

• Design review and credit targeting — early-stage analysis of achievable credits, cost-benefit mapping, and certification level strategy
• Energy modeling and simulation — whole-building energy models using EnergyPlus and eQUEST, optimized for local climate zones and utility rates
• Documentation management — complete LEED Online credit documentation, supporting narratives, and calculation templates
• Commissioning support — coordination with commissioning agents to satisfy fundamental and enhanced commissioning prerequisites

From Certified to Platinum

LEED v4.1 awards points across categories including energy performance, water efficiency, materials selection, indoor environmental quality, and innovation. The four certification levels reflect increasing commitment to sustainability performance.

ISG helps clients select the right target level based on project economics, market positioning, and regulatory requirements. In markets like Dubai and Riyadh, where LEED Gold is increasingly expected for Grade A commercial space, we ensure projects meet both certification requirements and tenant expectations.

Our track record includes projects certified at every level, from LEED Certified warehouses and industrial facilities to LEED Platinum headquarters and cultural institutions. The right level is the one that delivers measurable value — lower operating costs, higher tenant retention, and regulatory compliance.
