How are LEED points used to determine certification level?

• A. Certification level is based on the building's size and occupancy.
• B. The total earned points determine whether the project is Certified, Silver, Gold, or Platinum (in applicable programs).
• C. Points are used only for energy-related categories.
• D. Certification levels are assigned by the project budget.

Answer: (B)

LEED uses a points-based system. A project earns points by meeting prerequisites and by achieving credits across various sustainability categories. The total number of points collected is then mapped to a certification level defined by the rating system’s thresholds. The higher the point total, the higher the level—ranging from lower levels up to the highest Platinum level in applicable programs. This means the certification level reflects overall project performance, not just one aspect.

That’s why the other ideas don’t fit: certification isn’t determined by building size or occupancy, and while energy efficiency credits contribute to the total, points come from many categories beyond energy. It isn’t set by budget either; it’s the result of what the project earns through its credits and prerequisites.
