A note from Hans

Hi, I'm Hans.

I run capital projects and sustainability programmes across Southeast Asia: data centres, semiconductor facilities, workplaces. LEED is part of my working week, not a subject I teach from a distance.

LEED v5 changed more than any version before it. New credits, new names, new thresholds, and a new exam format. I wanted practice exams that teach the v5 rating system as it is, not v4 with new labels. So I wrote them from the source documents, and every answer is checked against those documents before it goes live.

If you're studying alongside a full-time job, I've built these for you.

Hans

How each question is made

Three steps, every question

  1. 1

    Start from the source

    Every number, threshold and point tier comes from the current rating system. For LEED v5 that's the July 2026 editions.

  2. 2

    Write to the blueprint

    One correct answer, as on the real exam. Wrong options are real mistakes people make, including the v4 answer where it differs.

  3. 3

    Check it a second time

    An independent review re-reads the source and tries to break each question before it's published.

Why v5 needs new material

LEED v5 is a rewrite, not an update.

By USGBC's own count, 32 of the 51 prerequisites and credits in LEED v5 BD+C are new, and the rest were renamed, merged or rewritten. The v5 AP exams are standalone specialty exams, with no combined Green Associate sitting.

A practice bank recycled from v4 teaches you the wrong credit names, retired thresholds and an exam format you won't sit.
