Chock full of mock test questions that simulate the actual exam to a tee. This book should be your first stop on the road to your LEED AP O&M...and then your last stop...Highly recommended.

From the Author
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 categories.
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 GA Exam, you can take USGBC courses or workshops. You should take USGBC classes at both the 100 (Awareness) and 200 (LEED Core Concepts and Strategies) level to successfully prepare for the exam A one-day course can cost $445 if you register early enough, and can be as expensive as $495 if you miss the early bird special. 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.
