LEED Exam
LEED Exam
(OP)
I am located in North Carolina and intend to take the LEED exam around March this year.
So far I have been to one LEED seminar (on schools) and am currently reading my way through the LEED for new construction book. This is such a "dry" read though and find it har to absorb at times.
Has anyone taken the LEED exam recently? What is it like? I have heard it is much more obsure and difficult than it used to be.
Can anyone give me some idea on what the best way to go about studying and more importantly retaining te knowelege (not just to pass the exam). I hav heard about study guides and flash cards. Are these worth while?
Thanks for any advice and help.

Before taking the test, you might want to look into the new credentialing program LEED will adhere too!
Good Luck!

I'm very interested to see if it becomes an adopted 'green' standard.
Calls for better 30% than ASHRAE 90.1 for energy (good).
Calls for 30% more fresh air than ASHRAE 62. Totally disagree with that. Not that I think that more ventilation is bad, just don't understand the message they appear to be passing along. Are buildings built to ASHRAE 62 under-ventilated? Why don't they just increase the ventilation levels in ASHRAE 62.

Quite often buildings here once they develop a problem, they fly in a CIH and like clockwork the solution suggested is "more air". So the client adds more air and the problem gets worse.
That is typically when the client will pay to find out what is really wrong. It's the IAQ Catch 22.You ventilate to give good indoor air quality, and it drives up humidity and gives you a rampid mold problem. A lot of things can be wrong with a building, it is just that the HVAC system is always the first to get blamed.
Worse buildings-- constant volume systems ventialted to old versions of 62. Inspired by lawyers who added the term 'sick building' to their vocabularies.
Its easy to add more air up north, you just throttle open a gas valve a little more to deal with it. It gets tough to deal with in a humid climate, when you are pulling that mositure out with compressors and your power is diesel generated.
Stop building with toxic materials.I will take high CO2 levels any day over mold and mildew

Consider off gassing for example. Do you calculate passed on how much to dilute?
Take a nuclear sub, you have the crews breathing air that is upwards to 1% CO2
One method I found in Canada, that seemed to appease my worst hypochondriac customers, was to give them enough air to keep their windows from condensating in the winter

RE: LEED Exam
CO2 levels are basically just an indicator of how much fresh air a person gets.
We wetted our fingers and stuck them in the air to see which way the wind is blowing. We recovered from a general lack of fresh air and had high ventialtion rates and saw the effects, now we are whittling them down to be workable
It has been a 30 plus year trial and error process since the Yom Kippur War and the Iranian Revolution.
You get 3 CIH's at a table and you cannot even get them to agree on what kind of pizza to order

RE: LEED Exam
Additional ventilation is easier in a dry climate, but expensive! My complaint isn't at the ventilation levels, but just that ASHRAE would publish a standard requiring a space to have more ventilation that the minimum ventilation standard they publish.
If the concessus is that we're underventilating buildings, change the standard.
RE: LEED Exam
We build with better windows but we also build tighter houses in Canada. With the extrme cold I think you will be hard pressed to keep much more than 35 to 40% indoors in winter time. NW Ontario, humidifers were extinct on new construction since about the late 80s
I have been montioring CO2 levels on and off in my own home down here. Take a constant ASHRAE 62.2 approach, tried itnermittent ventilation as well, sort of high speed version what the old HRV code was -- comapring 0.3ACH to the so much per habitable room rate
The only way to get it perfect is a dedicated supply of fresh air to each and every room if you ask me.
Should see master bedroom CO2 levels, worse when you get lucky

I took the short course on the 2007 vesion at the AHR in Manhatten last year, and I was pressing for an expalnation of how they came up with the rates.
The per sqaure foot amount is to do with the off gassing.
So if you have some stinky cheese or smelly rubber, you need to bump it up accordingly and that is engineering judgement and something you really only can learn the hard way.
