[Equest-users] LEED Review Comment - Exhaust Fans

[Kelsey VanTassel]

Of course I expect the modeler to understand all of the ins and outs of a particular software. Ideally, they would know exactly what every line of code means. But, the reviewer does not need anywhere near this level of understanding to judge whether or not Appendix G is being followed properly. For example, if they see that you did not use the correct baseline glass assembly U-factor and tell you to change it, they do not need to know what you should enter for the GLASS-CONDUCTANCE in eQUEST. The modeler had better know, though!

In my experience, out of the hundreds of GBCI comments that I’ve received for EAc1 over the years, all but a few of them have been good comments.  Courtesy and explanation go a long way (for those of you that have worked with the DOB and DEP in NYC, you know what I mean).  GBCI has tried to minimize some of the work that us engineers have to do (like implementing the Licensed Professional Exemptions) – if we end up getting more comments for EAc1, or some of them are not 100% accurate, no offense, but you may just have to deal with it.  If you disagree with a reviewer, explain it in polite terms, and 99% of the time, you’re explanation will be accepted.  After all, you’re the engineer (or modeler).  And again, I reiterate that if you have questions that are fairly easy to answer, just shoot an email to the project coordinator at GBCI and they can probably find someone that can answer your question (and you can then reference that response).

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,

Nathan Miller, PE, LEED®AP

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
