<div>Omer---I have your reviewer also on one of my projects...I literally just finished the 33 comments back to the reviwer only 6 hours ago. I'm exhausted and frustrated (hopefully I'm not alone in these feelings after fighting with LEED & GBCI...)</div>
<div> </div>
<div>I had the exact same comment, but I already had the exhaust fans in both the baseline and proposed. I was also told to break-out the fan energy which was annoying to have to back-track on these tedious things, add an extra meter, etc.... I also ran into the same issue of mis-match output results and I could not track what was the cause of it. I ended up explaining how the discrepancy in energy is literally negligible in the whole building picture of annual energy use. Exhaust fans and motors are small--in the sense of the ones they are refering too and to spend a whole hour fixing, revising, and rewriting explanations in the hopes that I appease this reviewer is EXHAUSTING and FRUSTRATING....also this change made virtually no change or difference in my overall results comparison as my reviewer pointed out that these fans are considered process loads and therefore are held equal in both cases...UGH. </div>
<div> </div>
<div>Further more, it ultimately feels that GBCI and the LEED Reviwers are always "out to get us"....What's going on with the LEED Comment discussion on Assembly U-values being unacceptable???!!! I have never had a LEED reviewer comment about this modeling approach and I've completed LEED sims from LEED version 1.0. This is really starting to get to be tooo much of a double standard for inconsistencies within the GBCI EAc1/EAp2 reviewers. The amount of work that is required for the reporting is ridiculous. Why do the new forms make us simulators take time to transpose the Appendix D climate characteristic data from 90.1 into the LEED template....</div>
<div> </div>
<div>There doesn't seem to be much support or comfort when "working for" a LEED reviewer and to TAKE THE CAKE....several comments in my LEED review were unprofessional on thier part AND they are incorrect! For example my LEED reviewer takes the liberty to state: "...<span style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 12pt"><em><span> </span>Table G3.1.1B indicates that the heating type for system type 7 is hot water fossil fuel boiler only, <span style="BACKGROUND: yellow">so there must not be any energy consumption for electric space heating</span>.<span> "...</span></em></span></div>
<div><span style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 12pt"><em><span></span></em></span> </div>
<div><span style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 12pt"><span>The following was my response back to them where based on my 10+ yrs of simulation & HVAC design experience warranted thier statement ignorant and unprofessional in my opinion. Statements like this from GBCI Reviewers are insulting to experienced simulators (maybe to inexperienced simulators too?) and only make the LEED Reviewers look inexperienced and unknowledgable---which makes me question thier ability to adequately review my energy models:</span></span></div>

I just added these exhaust fans to my baseline model. The reviewer is also asking for a separate energy consumption calculation for the exhaust fans. While trying to capture this through separate meters, I just realized that the air volume exhausted through some of these independent fans is variable in hourly reports even if I define them to be constant volume. I am afraid that this will result in mismatching values for energy consumption between the baseline and the proposed models.<br>
<br>1. What could be causing the air volume to be variable?<br>2. Is it a must that both the baseline and the proposed cases should display exactly the same amount of energy consumption for these independant fan systems?<br>

Those values that you have under EF-1 thru EF-9 need to be equal between baseline and proposed model. So, if you have EF-1 at 300 cfm and 2KW for that fan, you need to input the same values in baseline model. Those fans are separate than the Exhaust from the AHU. I usually input them at space level and the kw/cfm for those fans.<br>

Subject: [Equest-users] LEED Review Comment - Exhaust Fans<br><br></div>
<div>
<div></div>
<div>Dear All,<br><br>We have received the following from GBCI regarding the energy modelling<br>review:<br><br>"Table1.4.2 indicates that exhaust fan systems are reflected in the Proposed model; however, the equipment capacities are inconsistent with the exhaust fan systems (EF-1 through EF-9) as indicated in the mechanical schedules provided for PI Form 4: Schedule and Overview Documents. In addition, the independent fan systems of the HVAC systems in the actual design must be modeled identically between the Proposed and Baseline models at actual equipment capacities (fan volume and fan power) as required by Table G3.1.10 in the Proposed building column, since the fan design air flow rates and fan power per Sections G3.1.2.8 and G3.1.2.9, respectively, only applies to system types 1 through 8 in Table G3.1.1A.<br>
Revise the<br>Proposed and Baseline models so all independentfan systems of the HVAC systems are modeled identically between the Proposed and Baseline models. In addition, separate the energy consumption and peak demand energy for independent#fans in Table EAp2-4 and Table EAp2-5 of the prerequisite form. Further,provide revised SV-A reports reflecting the changes"<br>
<br>Our proposed model has supply and exhaust fans (Supply: AHU, FCU -<br>Exhaust: AHU, independant exhaust fans). Our baseline model has supply and relief fans (VAV System).<br><br>Please look at Section 6 of the attached Table 1.4.2. Are we expected to additionally model exhaust fans in the baseline case? Do they mean exhaust fans when they say "independent fan systems of the HVAC systems?".<br>
