LEED Process
How certification actually works
LEED certifies projects, not people or products. A project selects a rating system family - Building Design and Construction (BD+C), Interior Design and Construction (ID+C), Operations and Maintenance (O+M), Neighborhood Development (ND), or Homes - and then a specific adaptation (schools, retail, healthcare, data centers, warehouses, hospitality) where one exists.
Within a rating system, points live in credit categories: Integrative Strategies, Location and Transportation, Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality, plus Innovation and Regional Priority. Each category contains prerequisites (mandatory, worth zero points) and credits (optional, worth points).
The certification ladder
A project must first satisfy the Minimum Program Requirements: a permanent building or space, a reasonable and defensible site boundary, compliance with environmental laws, minimum floor area and occupancy, and a commitment to share whole-building energy and water data. Then it registers in LEED Online, submits documentation, and GBCI reviews it (typically a preliminary and a final review round). Credit Interpretation Rulings and appeals exist for genuine ambiguities. O+M projects recertify on a recurring cycle.
Traps candidates fall for
- A missing prerequisite voids the whole certification. Fifty points plus one failed prerequisite equals no certificate.
- Point thresholds do not shift by rating system: 40-49 Certified, 50-59 Silver, 60-79 Gold, 80+ Platinum.
- A LEED Accredited Professional on the team does not make the building certified; the credential is personal and simply earns an Innovation point.
Rule of thumb
Memorize 40 / 50 / 60 / 80 and the phrase prerequisite first, points second. Worked example: a project scores 62 points but skips construction activity pollution prevention - the result is uncertified, not Gold.
