Review Complete overview for the LEED GA exam

I studied this book for about three days and passed the exam...if you are truly interested in learning about the LEED system and green building design, this is a great place to start.

I just finished taking the LEED GA exam and, thankfully, I passed it on the first try by using this book as my primary study guide...I particularly liked the way the author organized the information within it. -----Lewis Colon

Finally! A comprehensive study tool for LEED GA Prep!

I took the 1-day Green LEED GA course and walked away with a power point binder printed in very small print, which was missing MUCH of the required information (although I didn't know it at the time). I studied my little heart out and took the test; only to fail it by 1 point. Turns out I did NOT study all the material I needed to in order to pass the test. I found this book, read it, marked it up, re-took the test, and passed it with a 95%. Look, we all know the LEED GA exam is new, and the resources for study are VERY limited. This one's the VERY best out there right now. I highly recommend it. -----ConsultantVA

A Great Book for Preparing the LEED Exam!

I have read almost all the books for LEED Exams, and found LEED Exam Guide Series to be the best. The USGBC Reference Guide was too detailed and kind of confusing. Some other third party books have too many grammatical mistakes and are hard to understand, and way too many questions. The questions in those books are confusing instead of helpful. The USGBC workshop missed some of the very important information, like extra credits.

LEED Exam Guide Series gives you just the right amount of information for you to pass the LEED exam. Each book in the series includes study materials, sample questions and answers, as well as mock exam and answers for a specific LEED exam. It also gives you the most information for you to get your building LEED certified. A Great book! -----Ellen

My name is Elizabeth (last name deleted to protect her privacy) and I am a junior at the University of .... (college name deleted to protect her privacy). This summer I attained an internship with Kath Williams and Associates, a collaborative of creative independent contractors who come together to support innovative green projects, to learn about sustainable building. At the beginning of July I spoke with Kath about taking the LEED Green Associate Exam. After having no prior experience in sustainable architecture or LEED buildings I used both your review book and the study guides by USGBC as my study references. I wanted to e-mail to thank you for such a comprehensive review guide that was enormously helpful in passing the exam. Without your guide I don't know if I would have passed. Thank you so much. -----Elizabeth

A Great Timesaver!

Like other books in the LEED Exam Guide Series, this is a great timesaver! The important information that you need to memorize is already highlighted / underlined by the author. This can really save me a lot of time. I love it! A Great Timesaver! -----Alice

From the Author
What others are saying about LEED GA Exam Guide...
Very effective study guide
I purchased both this study guide and Mr. Chen's LEED GA Mock Exams book and found them to be excellent tools for preparing for the LEED Green Associate exam. While Mr. Chen's LEED Green Associate Exam Guide is not perfect (in that it's not the most user-friendly presentation of the material), it was very effective in at least presenting most, if not all, of the topics that the exam touched upon. While I wouldn't necessarily recommend my abbreviated strategy for preparing for the exam, the following worked for me: I read through the exam guide a couple of times (but not word for word), took the mock exam and referenced the guide for explanations for any wrong answers, did the same for the two mock exams in Mr. Chen's LEED GA Mock Exams book, flipped through the documents at the bottom of this page that Mr. Chen recommends, and took two other web-based mock exams that I purchased on eBay. Literally after ten hours of preparation time, I took the actual exam and passed with a 189, thanks in large part to Mr. Chen's books. If I decide to take one of the LEED AP exams in the future, I will definitely be picking up more of Mr. Chen's study materials.

Latest trend for LEED Exams

Recently, there are quite a few readers run into the versions of the LEED exams that have many questions on refrigerants (CFC, HCFC, and HFC), the following advice will help you answer these questions correctly:

For more information, see free pdf file of "The Treatment by LEED of the Environmental Impact of HVAC Refrigerants" that you can download at link below:


This is a VERY important document that you need to become familiar with. Many real LEED exam questions (CFC, HCFC, and HFC, etc.) come from this document. You need to download it for free and read it at least 3 times.

Pay special attention to the Table on ODP and GWP on page 3. You do not have to remember the exact value of all ODPs and GWPs, but you do need to know the rough number for various groups of refrigerants."

This latest trend regarding refrigerants (CFC, HCFC, and HFC) for LEED Exams has a lot to do with LEED v3.0 Credit Weighting. EA (including refrigerants) is the biggest winner in LEED v3.0, meaning the category  has MORE questions than any other areas for ALL the LEED exams. See pages 36 to 38 of my book, LEED GA Exam Guide quoted below:

How are LEED credits allocated and weighted?

Answer: They are allocated and weighted per strategies that will have greater positive impacts on the most important environmental factors:  CO2 reductions and energy efficiency.

They are weighted against 13 aftereffects of human activities, including carbon footprint / climate change (25%), indoor-air quality (15%), resource/fossil-fuel depletion (9%), particulates (8%), water use/water intake (7%), human health: cancer (7%), ecotoxity (6%), eutrophication (5%), land use/habitat alteration (5%), human health: non cancer (4%), smog formation (4%), acidification (3%), and ozone depletion (2%).

These 13 aftereffects were created by the U.S. Environmental Protection Agency (EPA), and are also known as "TRACI
", a mnemonic for "Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts."

1) The USGBC used a reference building to estimate environmental impact in the 13 categories above.

2) The USGBC also used a tool developed by the National Institute of Standard and Technology (NIST) to prioritize the TRACI

3) The USGBC also created a matrix to show the existing LEED credits and the TRACI
 categories, and used data that quantify building impacts on human health and environment to allocate points for each credit.

The points for Energy and Transportation credits have been greatly increased in LEED 2009, primarily because of the importance to reduce carbon or greenhouse gas emissions. Water Efficiency is also a big winner in the credits, doubling from 5 to 10 points for some LEED rating systems.

In addition to the weighting exercise, the USGBC also used value judgments, because if they only used the TRACI-NIST tool, some existing credits would be worth almost nothing, like the categories for human health and indoor air quality. The USGBC wanted to keep the LEED system somewhat consistent and retained the existing credits including those with few environmental benefits. So each credit was assigned at least one point in the new system.

There are NO negative values or fractions for LEED points.

20% reduction of indoor water-use used to be able to gain points, now this is a prerequisite in LEED 2009.

USGBC and GBCI seem to enjoy confusing LEED exam takers and making their lives miserable

One thing that I notice is that USGBC and GBCI tend to spread their information everywhere, but not in one place. They seem to enjoy confusing LEED exam takers and making their lives miserable.

For example, they have some information regarding the responsible party and project phase or case studies that are part of their workshops, but not in their reference guide; they also have a lot of information that is at the GBCI and USGBC websites, but not anywhere else, such as CIR guidelines, MPRs and related requirements, etc. I just finished writing " LEED Green Associate Exam Guide" (published on 12/22/11), "LEED GA Mock Exams " (published on 3/9/12), "LEED BD&C Exam Guide" (published on 1/26/12), "LEED ID&C Exam Guide" (published on 1/28/12), "LEED ID&C Mock Exam" (published on 1/28/12) and "LEED O&M Exam Guide" (published on 1/27/12).  Another thing that I notice is that because USGBC has expanded the LEED systems so much, they have to have different task groups to write different reference guides, but they are NOT even consistent between reference guides for different LEED systems. It seems like their tasks forces do not even talk to each other and coordinate: For example, ALL LEED systems were based on the platform set by LEED NC, but for EAp2, LEED CI only listed 2 related credits as synergies, but the LEED NC has included MANY more credits for synergies for the same credit, and most of them DO apply to LEED CI also, but the LEED ID+C reference guide misses these credits. Page 121 of LEED Interior Design and Construction Reference Guide also mistakenly listed EAp1 as IEQp2 under Domestic hot water systems for Table 1.

If you are taking the LEED AP ID+C Exam, USGBC suggests you to take USGBC classes at both the 100 (Awareness) and 200 (LEED Core Concepts and Strategies) level to successfully prepare for Part One of the exam. USGBC classes at 300 level (Green Interior Design & Construction: The LEED Implementation Process) can be taken to prepare for Part Two of the exam. A one-day course normally costs $445 (as of publication) with an early registration discount, otherwise it is $495. You will also have to wait until the USGBC workshops or courses are offered in a city near you.

The problem is: when you go there, after you spend 8 hours and close to $500 for each workshop, the instructor will tell you that the workshops are NOT for LEED exam prep. Come on, you have just spent so much money and time and go through the trouble for the workshops, and they just tell you now the workshops are NOT tailored for the LEED exams? Give me a break.

So, I think third party books are absolutely necessary and they are much more helpful than the USGBC publications and workshops or GBCI and USGBC websites alone.

You can find sample texts and other information on the LEED Exam Guides Series in customer discussion sections under each of my book's listing on Amazon.

I have to say I love this idea, it solved a big problem.
