1. In any climat a solar hot collector would contribute to achievement of which LEED credits

a. EA c2 Renewable Energy

b. EA c1 Optimize Energy Performance

c. None of the choices

d. EA c1 Opetimize Energy Performance & EA c6 Green Power

Answer is C. Why not b????

(Their explaination is: Solar hot water heating does not apply LEED credits.)

Why?

Have you looked at http://downtheline.wordpress.com ? Her memorizing techniques are insanely helpful!

Does anyone have any tips for memorizing? With a week to go, i’m having a devil of a time remembering all the percentages. It’s not as when i was 25!

The relationship between building size, orientation, how deep it is (skin vs. area), light loads, daylight, solar gain, are very complex, and the “give and take” strategies are complicated, even for me, as a practicing architect.

The EA1 section is very complicated, and you may not spend your time wisely trying to understand it fully.

I just took the test, and there were very few questions from EA overall. I could have anwsered them all by knowing the following:

-EAc1 gets the most points from ASHRAE 90.1 Performance Rating Method (whole building modeling)
-The energy model gives you energy cost info for a baseline case and a design case.
-Those costs allow you to determine energy offsets for EA2 and EA6.
-daylighting increases energy required
-incresed ventilation increases energy required.
-without the EA1 energy model, by using other compliance paths, CBECS must be used to estimate energy usage for EA2, and EA6.

Personally I burned a lot of time on EA1 and EA5, when less than 4 qustions came from those 2 sections. Most came from WE, MR, and EQ.

Another LEED AP Walkthrough vs LEED Reference Guide (2nd Ed) question– i do not have access to 3rd edition.

The APW stats no calcs are required–was the
Option 2 [LCGWP + LCODP x 10.....] abandoned for more simplified language in V2.2 3rd Edition?

Thanks, Jon

Pat you mention that the summaries in AP Walkthrough provide enough info to pass the exam, but calculations, like “double the baseline” or % thresholds attached to Energy Star Ratings seem to step into calculations, the memorization of which seems practically impossible.

No area of LEED has me more confused than EAC1. As a Landscape Architect, many of the questions that address tradeoffs between specific design features like “shallow floor plate” or specific types of HVAC systems step into areas that i have no basis for knowing the answers to.

Can anyone provide any advice or set me straight. Exam is on June 21 so this is a 1 shot deal!

The CEO of a successful recording label is committed to reducing the environmental impact of a studio project both by reducing the amount of energy used in the building, and by making sure that the energy used comes from more benign sources. The structures, which will be a major renovation of an old theater, uses green noise barriers with low-VOC adhesives. Additionally, it obtains 15% of its energy by cost from a roof-based photovoltaic system while improving the baseline energy performance by twice of that. The CEO also opts to purchase green power for 35% of the building’s energy use for 4 yrs after its construction.

Which points could this recording studio achieve for its energy innovations under these specifications (choose 4)

A. (1) for EAp2, min energy performance
B. (1) for EAc2, On-site Renewable Energy
C. (1) for EAc6, Green Power
D. (1) for IDc1, Innovation in Design
E. (3) for EAc2, On-site Renewable Energy
F. (3) for EAc6, Green Power
G. (6) for EAc1, Optimize Energy Performance
H. (8) for EAc1, Optimize Energy Performance

Sorry its a long question.
Ans: C, D, E, H

I don’t understand H. Any thought?

Thanks!

Using rooftop photovoltaic panels supplying 17.5% of a building’s energy needs would help a project comply with EAc2, On-Site Renewable Energy, and with other credit:

A. ID Credit 1, Innovation in Design, for exemplary performance under EAc2
B. EA Credit 1, Optimize Energy Performance
C. EA Credit 6, Green Power
D. SS Credit 7, Heat Island Effect

Answer is B, but why not A? per reference guide, you get an EP point if you reach 17.% r greater?

Thanks in advance!

Answers are a, b & c. ON further reading of the reference manual – option1 Onsite- Renewable energy and site- recovered energy costs are not included in the proposed building performance, therefore these systems receive full credit using the performance rating method.

Question how does renewable enery fit in the calculation?

When I google your question, I get the answer to be A-C-E on the usgbc website.

http://www.usgbc.org/ShowFile.aspx?DocumentID=3178

Jessie you are right, I think I’m more confused jeje

Where did you pull the question from. I know I’ve seen it, but I pulled from all sources too. Do know that all sources, and even the AP Exam itself, may contain errors.

Better stated, all study sources I’ve encountered definitely contain some degree of errors. The Exam itself may contain errors.

B is for site elements.
D is for the quality of air.

i choose c,d,e but the answer is a,c,d does anyone knows why a???

Can something help me with this, I did not see any mention of synergies in the M/V section regarding LEED-EB??

Which ONE of the following scores represents the average building performance of
ENERGY STATR for achieving EA Credit 1, Optimize Energy Performance credit?

A._____ 60
B._____ 90
C._____ 50
D._____ 75
