What is LEED?
LEED is a global green building rating system that helps projects measure energy, water, materials, indoor environmental quality and broader sustainability performance.
LEED Certification
Plan, document and certify LEED projects with clear scorecard and submission support.
Service overview
What is LEED Certification?
LEED Certification is an internationally recognized green building rating system that evaluates site planning, energy, water, materials, indoor environmental quality and operations. It fits developers, building owners, designers and corporate teams seeking a structured path for sustainable building performance. INDEX helps review project goals, coordinate documentation, advise design strategies and support the certification process with practical, project-ready guidance.
LEED
Explore the pathway
LEED process
Define goals, confirm rating system, build scorecard, coordinate design evidence, submit documentation and respond to review comments.
Documentation
We organize drawings, calculations, narratives, product data and commissioning records so the project team can submit with confidence.
Readiness checklist
Start with owner goals, project boundary, energy baseline, water strategy, material targets, indoor air priorities and documentation responsibility.
LEED service types
Select the LEED pathway that matches the asset.
Different project types need different evidence, teams and timing. These pathways keep the certification scope clear from the start.
LEED Certification Consulting
End-to-end consulting for rating system selection, scorecard strategy, credit coordination, documentation and review responses.
LEED Certification for Existing Buildings
Certification support for operating assets using performance data, policies, maintenance records and practical improvement measures.
LEED Certification for Interior Spaces
Guidance for tenant fit-out and interior projects covering materials, lighting, comfort, indoor air quality and documentation responsibility.
LEED Zero Certification
Performance-based support for projects pursuing net zero recognition in carbon, energy, water or waste.
LEED checklist
Technical workstreams that keep LEED documentation moving.
Use this checklist to align modelling, commissioning, audits, water, IEQ and physics analysis with the certification schedule.
-
01
Building Energy Modeling / Simulation
Model building performance to compare design options, test LEED energy credits and support decisions before systems are fixed.
-
02
Commissioning & Verification
Plan commissioning scope, organize verification evidence and help teams confirm that building systems operate as intended.
-
03
Energy Auditing
Review actual energy use, operating patterns and improvement opportunities to support LEED readiness and performance planning.
-
04
Building Simulation - Day lighting & Building Physics
Use daylight and building physics analysis to improve comfort, energy performance and evidence for relevant LEED strategies.
-
05
Water Efficiency and Management
Assess indoor and outdoor water strategies, fixtures, reuse opportunities and management evidence for LEED water credits.
-
06
Indoor Environmental Quality (IEQ) Design
Coordinate air quality, ventilation, materials, lighting, acoustics and comfort strategies that support healthier indoor environments.
-
07
Energy Auditing
Recheck energy use after design or operational updates so the LEED team can confirm savings, risks and next actions with current data.
LEED v5 certification
Choose the performance level that fits your ambition.
LEED certification levels are based on the total points achieved. Gold is the most popular target for ambitious projects seeking balanced performance.
Certified
40–49 pointsA verified foundation for high-performance green building.
Silver
50–59 pointsStronger integration across carbon, health and resilience.
Gold
60–79 pointsThe most popular target for ambitious, balanced project performance.
Platinum
80+ pointsLeadership performance at the highest LEED certification level.
FAQ
Common questions
Which LEED certification level should a project target?
The appropriate target depends on the project type, owner priorities, budget, schedule, site conditions and achievable credits. We confirm a practical target through an early scorecard workshop.
When should LEED consulting start?
Start during concept or schematic design, before energy, water, materials and indoor environmental strategies are fixed. Early coordination creates more options and reduces redesign risk.
Can an existing building apply for LEED Certification?
Yes. Existing buildings can pursue LEED O+M (Operations and Maintenance), which focuses on measured operational performance such as energy efficiency, waste management and indoor air quality improvements without demolishing or rebuilding the whole asset.
