LEED Green Associate

Today I am pleased to report that I have passed the LEED® Green Associate exam, so I am now officially a LEED-accredited professional.  I have a few thoughts on this process that might be helpful for others looking into getting their own LEED Green Associate credential.  While I'm certainly in support of sustainable building practices, which is why I went to the trouble to get the credential in the first place, I don't think it's inappropriate to take a critical stance toward the whole enterprise in order to challenge the profession (and the industry) to be more self-aware.

The preparation: I passed the exam by using only resources that were freely available to me through my school library, including an e-book version of the LEED Green Associate study guide by Michelle Cottrell and the USGBC LEED Core Concepts Guide.  (Although I asked the library to obtain a new copy of the official USGBC LEED Green Associate Study Guide since the one they had was lost, they still haven't gotten it in.)  I read all the free, online "primary sources" for the exam, plus looked at a few additional websites on specific things like the ACEEE's Green Scores for cars and the text of the SCAQMD Rule 1168.  I started studying in January during my winter break, did most of my studying then, and continued off-and-on until now.  I felt reasonably well prepared for the exam.  I also took one free full-length practice exam offline and a couple of other free practice exam question sets, but I didn't buy any practice exams or books or anything else.  I should disclose that I was pretty determined from the outset not to spend any money beyond the exam fee, since I'm quite skeptical of the whole test-prep industry.

The exam: My general impression of the exam was that it was poorly written, with ambiguous answers on numerous questions, and poorly calculated, with a grading format that makes it nearly impossible to judge how well you will do in advance.  The exam is 100 questions, but is graded on a scale of 125 to 200 points, with 170 as the cutoff for a passing score.  The questions are unequally weighted, so missing one question doesn't translate directly to missing 2 points; in addition, there are an unknown number of unscored "trial" questions thrown in that are being tested for future versions of the exam.  Further, many questions have multiple correct answers, all of which must be chosen correctly to receive credit (no partial credit, but no guessing penalty).  So up until I submitted my exam and saw my score, I had no idea whether I would pass or not.  There were a number of questions I wasn't completely sure about, but I didn't know whether it would be too many.  I was relieved to see that I passed with a fairly wide margin, but then again, the margin was practically meaningless since I couldn't tell with any certainty how many right answers I needed to pass.

Conclusions: Perhaps the goal is to make it so that applicants feel they need to know every answer in order to pass, to encourage them to study the material more thoroughly, but since it's nearly impossible to understand some of the exam questions, it's really just nerve-wracking to study for this exam.  So be prepared for that.  I was also amused to see that while I got between 90-100% correct on six of the seven exam "categories" (these are seemingly arbitrary categories, not actual divisions in the exam, that are described in the exam specifications), I only got 67% correct in the "Stakeholder Involvement in Innovation" category.  I don't really think that I am particularly deficient in this area.  Were there only three questions in this category, out of the 100 exam questions, and I missed one of them?  I'm guessing that I only missed between 4 and 6 questions total, so I couldn't have missed that many in the one category.  Bizarre.

Anyway, if I learned anything from this experience (besides a lot of more-or-less useful information about green building practices and LEED certification), it's that the exam isn't very easy, and it helps to read the study guides and sample exams, since they acclimate you to the vague green-speak of the USGBC which is necessary to understand the exam questions.  There were a few straight-up memorization questions that seemed unnecessary, testing you on things from a table in the primary sources (do I really need to memorize all the different types of HCFCs and their respective global warming potentials?  In a real-life project, I would just look this up).  There were also quite a few vague questions without clear answers.  All told, I'm very glad to be done with it!  Now on to saving the world, one low-embodied-energy building at a time.

  1. Hey, I'm starting to study for the LEED GA Exam and I was wondering where you found your free offline practice exam questions. Your review of the exam was very helpful and I'm glad to know that you do not need to fork over obscene amounts of money to do well on the test. Thanks for the help!

  2. Thank you Caroline for an outstanding review of the exam. I will be taking the same exam next week. The public libraries in my area don't have the study guide for LEED. Do you by any chance know if there is any free study guide?

  3. As far as I know, there is no free study guide available. I found practice exam questions at the following sites: and Good luck!

  4. Caroline, I respect your honesty and reflection about the whole experience. I am pretty nervous about taking V3 of this exam and deciding to take the exam 2 weeks before the test date has a lot to do with it- but, I am very grateful for the road leaders who share their exam experiences. Thank you!

    1. Thanks Jennifer, good luck with your exam!

  5. Thank you for sharing your thoughts, Caroline! Congratulations! I also hope to take the exam this year and just like you, I will challenge myself to go through a self-study mode at the least possible cost. :) I heard that v4 is now the coverage so I hope I will be able to get "fresher" materials online. Thanks again! Happy for you! P.s. For your future readers who are also would-be LEED Green Associate examinees, please feel free to contact me through my blog. Maybe we can study together and share notes! :)

  6. Great Post! If someone is looking for practice exam questions for LEED Exam, visit and Good Luck!

  7. I appreciate everything you have added to my knowledge the time and effort you put into your blog and detailed information you offer. Thanks.

  8. Hi Caroline,
    Is the green associate test exam is the same as the questions you have been listed above?

  9. Thank you Caroline for an outstanding review of the exam. I will be taking the same exam next week. The public libraries in my area don't have the study guide for LEED. Do you by any chance know if there is any free study guide? For more :

Vertical Bike Rack

The work of our hands!

A little backstory:  We bought two bikes as soon as we could after moving here, so we could both bike to work.  After a few uneventful months of chaining up our bikes next to our car in the carport of our apartment building, Justin's bike was stolen.  (Mine was mysteriously left behind, together with Justin's pannier, which the thieves helpfully folded up and placed on top of my bike.  My only guess is that the chain holding my bike was harder to cut than the chain on Justin's.)  Since then, we've kept our bikes inside, hauling them up and down two flights of stairs to our third-floor apartment every time we take them out, which is usually a few times a week.  Ugh.  Better than buying a new bike every few months, though.

We needed a rack that would keep the bikes off the floor, off the walls, and in as small a footprint as possible, without requiring us to drill into or otherwise damage the walls (or floor or ceiling).  This proved a challenge t…

Book Review: "Theory and Design in the First Machine Age"

Reyner Banham's Theory and Design in the First Machine Age (1960) is an engaging overview of the important theoretical developments of the early 20th century leading up to the "International Style" of the 1930s-40s.  Banham does a fairly good job, in my opinion, of avoiding excessive editorializing, although he has a clear viewpoint on the Modern Movement and finishes with a strong conclusion.  In opposition to his teacher, Nikolaus Pevsner, whose own history of modernism came out in 1936, Banham dismantled the "form follows function" credo that became the stereotype of modernism, arguing instead that formalism (a preoccupation with style and aesthetics) was an important, if not overriding, concern of Modern architects.  Two sections of the book struck me in particular: his analysis of Le Corbusier's famous book Vers une architecture (Toward a [new] architecture) from 1923, and his Conclusion (chapter 22), where he breaks the link between functionalism and …
