[Equest-users] LEED Review Comment - Exhaust Fans

[Paul Diglio]

Kelsey:

You opinion is frightening.  I hope you expect that a mechanical engineer 
understands what he or she is doing.

You state that it is understood that the team that does the energy modeling for 
a LEED project already has the necessary skills.

It is ridiculous to assume that the team that reviews the energy modeling for a 
LEED project does not require the necessary skills to review the project.

Sorry, but you lose, no matter how many replies you send.  The simulation 
reviewer needs to be competent, no if and or but.  Come on, Kesley, do you 
really believe that the simulation reviewer does not have to be competent in the 
appropriate software?  There are hundreds of inputs that eQuest requires, many 
of which are based on assumed operations.  How can a person unfamiliar with the 
software determine if the assumed inputs are reasonable?

I do not think reviewers need to understand all of the intricacies in the art 
and science of energy modeling to be competent reviewers. They are judging the 
energy modeling inputs and results in the context of LEED, not your skills as an 
energy modeler. It is understood that the team that does the energy modeling for 
a LEED project already has the necessary skills (whether or not this is actually 
true). LEED reviewers ought to be trained to spot “fishy” results and get a good 
feel for what sorts of energy cost savings are expected in various scenarios. Of 
course experience as an energy modeler would help with this, but I don’t think 
it is a necessary requirement. Especially since LEED already has a huge database 
built up of results to compare with.
 
I say this because I do a lot of energy modeling for Focus on Energy and I have 
a reviewer who is great a reviewing my modeling results. He knows immediately 
when something “isn’t right,” but he does not do very much modeling himself. His 
skills as a reviewer come from having looked at so many different projects.

Kelsey:

I do not understand why you do not expect the GBCI reviewer to be competence in 
the software used to simulate a particular building.  Your comment does not make 
sense.

It is the same as saying the modeler does not have to be competent in the 
software he or she uses to simulate the building.  Get real, there is a minimum 
level of competency required for both the simulator or reviewer on any project.

Why should LEED reviewers be expected to be experts in every type of modeling 
software? The software itself is just a calculator. As long as it meets the 
requirements, it shouldn’t matter which program was used. The LEED reviewers 
judge the models on the results and the quality of the inputs. Garbage In, 
Garbage Out.

Nathan:

I am being fair and I expect the reviewers to experts in every energy modeling 
program that is allow under Appendix G.  The GBCI should refer specific projects 
using eQuest or Trace or HAP to reviewers that are competent in that software.

Paul, 
 
I think you are being a bit unfair to the reviewers (full disclosure, I reviewed 
EAc1 submittals in the pre-GBCI days, when consulting teams performed the 
reviews). 

 
They don’t go into a review with all of the knowledge that we had while building 
up the model. All they get is the template and the supplementary documentation 
that we as submitters have decided to provide them. Sometimes these documents 
are a bare minimum, and sometimes it is a flood of information that is too much 
to try to go over.
 
They have to piece together if the saving you are presenting make sense given 
the building and system components that have been described. It can be quite a 
puzzle to figure out , for example, if it makes sense that someone is showing 
35% ventilation fan energy savings when comparing their series VAV system to the 
baseline parallel VAV system. Reviewers can try to be helpful, and point out 
specific items they want verified, though sometimes they do in fact make 
mistakes and look like idiots for what they are asking (I’m thinking of the 
electric resistance heating question from earlier in the thread). Alternately 
they can be vague with their comments and put the onus on the submitter to prove 
that the savings make sense, but that can be equally frustrating to respond to. 

 
Additionally I don’t think it is fair for them to be experts in every energy 
modeling program that is allowed under Appendix G. That is completely 
unrealistic. They won’t necessarily know that one program puts boiler 
supplementary energy in the space heating end use category, as that could be 
different with different programs, and certainly isn’t intuitive. 

 
Sincerely,

Pasha:

No problem, it is raping as far as I am concerned.  GBCI is using incompetent 
reviewers and they expect us to train them.  They take the application fees and 
offer nothing in return except ridiculous comments.

I have a similar problem with Northeast Utilities serving CT and MA.  NU offers 
a modeling incentive of $6,000, an efficiency incentive up to $2.00 ft2 and a 
LEED incentive up to $15,000.  They employ reviewers that have no modeling or 
eQuest experience.  One reviewer expected that I would explain how custom 
performance curves are built for an eQuest VRV system.

I told them I wasn't in the business of training their employees at the client's 
expense.  I would provide the manufacturer's performance tables and my eQuest 
curve coefficients, but I was not going to spend time to explain how to verify 
that my curves are accurate.  They need to spend money to train their reviewers 
or hire experienced reviewers.

I feel that the comments that you received from the GBCI were indicative of a 
person who has no clue and is not qualified to review building simulations.

Regards,

Paul Diglio

Hi Paul--  thanks for receiving my comment in the most professional sense of the 
term as it relates to the economics of the LEED simulation & Compliance 
markets. 
 
I didn't really feel it was unprofessional, but I didn't desire to offend anyone 
with the terms that i chose.   I was pretty sure that I wasn't completely alone 
with the 'feeling' or sense I was getting from others comments I've seen with 
the forum (past & present).
 
I offer a sincere professional apology if my chosen adjectives offended anyone.  
(were they adjectives?  I don't know I'm not an english major...)  :)
 
Cheers,
Pasha

Dear Pasha, 
 
client has already paid them.   DEAR USGBC---please stop raping the industry for 
the money monopoly that you have created.  The sense of GREED is oozing from 
everything that comes out of USGBC/GBCI with a price tag on it or a cost 
associated with it.
 
I hear that you are very frustrated with the review process, however, I find 
this kind of language inappropriate for a public forum and would ask that you 
take more care in the future.
 
With all best wishes,
Dan
