LEED Process
How the rating system is built
LEED ID+C (Commercial Interiors, Retail, Hospitality) is points-based. Prerequisites are mandatory and worth zero points; credits are optional and worth points; total available points scale to 110 including Innovation. Certification thresholds are 40 (Certified), 50 (Silver), 60 (Gold) and 80 (Platinum). Before anything else the project must satisfy the Minimum Program Requirements: a permanent, definable project boundary, a minimum floor area, compliance with environmental laws, and use of the correct rating system. The team then registers in LEED Online and submits documentation in the design and construction phases.
Roles, rulings, and rules
Know who does what: owner, LEED project administrator, commissioning authority, contractor, and the design team. A Credit Interpretation Ruling clarifies how a credit applies to an unusual condition; an appeal challenges a review decision. Questions love to swap these two. Also remember that prerequisites can never be traded for credits, that a strategy cannot be double-counted in two categories unless a credit explicitly allows it, and that the LEED project boundary drives what the tenant may claim.
Trap
Distractors often describe BD+C strategies (site-wide stormwater, building envelope, whole-building energy) as if a tenant fit-out could use them freely. ID+C credits are limited to what is inside the boundary and under the tenant control, although building-level performance may be used when properly documented and coordinated with the landlord.
Rule of thumb
Memorize 40 / 50 / 60 / 80, and remember that prerequisites consume real effort and earn nothing. Budget points where the project has the most control: energy, water, materials and IEQ inside the leased space.
