USGBC, LEED & IGBC

The credits, the four levels, and the certification process.

≈ 50 min + studio task

LEED is the world's most widely used green-building rating system. Learn its impact categories, its 110 points and four levels (Certified, Silver, Gold, Platinum); the Indian Green Building Council (CII), LEED-derived and India-adapted; and the certification process from registration, through design pre-certification, to a final certificate. Try the certification-level explorer.

Sequence the certification process from registration to final certificate.

Where points become a level

LEED & IGBC — credits and levels

LEED scores impact categories (Energy & Atmosphere the largest) for 110 points and four levels — and IGBC runs the same LEED-derived levels, India-adapted; Platinum is the top tier, not net-zero.[1, 2]

LEED — where the points come from Location & Transport Sustainable Sites Water Efficiency Energy & Atmospherethe biggest lever Materials & Resources Indoor Env. Quality Innovation Regional Priority Seven impact categories + Innovation + Regional Priority = 110 points. Each category has prerequisites (mandatory) and credits (optional points); energy is usually decisive.

Where points come from

LEED (USGBC, certified by GBCI) scores a building across impact CATEGORIES — Location & Transportation, Sustainable Sites, Water Efficiency, Energy & Atmosphere (the largest), Materials & Resources, and Indoor Environmental Quality — plus an Integrative Process credit and two bonus categories, INNOVATION and REGIONAL PRIORITY, that bring the total to 110 points. Each category has prerequisites (mandatory) and credits (optional points). The biggest lever is almost always Energy & Atmosphere.[1]

Register to certificate

The certification process

A project registers, submits design documentation, earns a design pre-certification, builds, and then earns a final certificate — assessed throughout by an independent third party, not self-certified.[1, 3]

The certification process Register Submit designdocumentation Design(pre-)certification Build FINALcertificate Assessed by an independent THIRD PARTY (GBCI, GRIHA Council, IGBC) — not self-certified. Pre-certification is provisional (drawings); the final certificate confirms after construction and review.

The certification journey

A project earns certification through a defined process: REGISTER the project with the rating body; assemble and SUBMIT design documentation against the credits; receive a PRELIMINARY / design (pre-)certification on the drawings and specifications; build; then submit construction evidence for FINAL certification, confirmed after a documentation and (often) site review. Pre-certification is provisional; the final certificate is the real one. The team does not self-certify — an independent body assesses.[1, 2]

Vocabulary

Key terms

LEED category

An impact area (e.g., Energy & Atmosphere) holding prerequisites and credits.

Prerequisite vs credit

A mandatory requirement / an optional point-scoring measure.

LEED levels

Certified (40), Silver (50), Gold (60), Platinum (80) out of 110.

IGBC

CII's LEED-derived, India-adapted rating family (Certified to Platinum).

Pre-certification

Provisional design-stage certification, confirmed later as final.

Third-party assessment

An independent body reviews the evidence — the team does not self-certify.

Apply it

Studio task

Imagine a project scoring 28 in Energy & Atmosphere, 12 in Water, 10 in Materials, 14 in Indoor Environmental Quality and 8 across other categories. Total the points and use the explorer to find its LEED level. Then name two categories where adding credits would lift it a tier, and explain why “Platinum” would still not mean “net-zero.”

Self-assessment

1. A LEED score of 65 out of 110 earns which level?

2. IGBC is best described as —

In a nutshell

Recap

LEED scores impact categories (Energy & Atmosphere the largest) for 110 points and four levels.
Levels: Certified 40, Silver 50, Gold 60, Platinum 80 — Platinum is the top tier, NOT net-zero.
IGBC (CII) runs LEED-derived, India-adapted schemes with the same level names, out of ~100.
Certification runs register → design pre-certification → construction → final certificate, assessed by a third party.
Assessment audits design intent and documentation — credible, but not a guarantee of operating performance.
