spreadsheet for clarity’s sake – not us... in that light I wouldn’t spend extra time improving their spreadsheet for them until they call for additional clarification through review commentary. If requested through review commentary, I’ll consider re-working
their spreadsheet for them as needed for clarity, but if they have locked it up in some fashion that this is overly difficult for us then they’ve shot themselves in the foot and will just have to deal with long, exhaustive narrative response essays (queue
the pipe organ and evil cackling)!<o:p></o:p></span></p>

documentation. The zoning pattern you determined appropriate to the models (remember 90.1 explicitly permits flexibility on the modeler’s part here) drives the separate task of applying these LPD’s to the models in a fashion that makes sense. Whatever degree
of detail you choose to invest your efforts in this task (there are always multiple right answers), it’s probably more important that you are careful to apply the Proposed & Baseline LPD’s to each model in an identical/consistent fashion.<o:p></o:p></span></p>

<br>
Thanks for the heads-up on the air films, Sheila also mentioned that.<br>
<br>
I tried some edits on the spreadsheet, but there are so many macros that I was messing it up. If you develop some handy hints, I would be interested to hear.<br>
<br>
One of the LPD problems I am having is that the EE did not zone the building as I did. As you know, we don't always zone every tiny closet separately. In addition this building has a L shaped corridor with an exit stair at either end. The EE chose to increase
the LPD for the 10' of the corridor in front of the stairwell doors so I need to apportion the LPD based on areas and percentages. Table 1.4 does not allow notes in the Lighting table. It would be so much easier to keep track of combined spaces and averaged
LPD's if a note section, per space, was provided. In the past, I have just sent the engineer's LPD spreadsheet and it was accepted by the GBCI.<br>
<br>
The spreadsheet does have some advantages in the Air Side HVAC tab. It will calculate the allowed fan power and highlight the cell in red if it is too low or too high. I find that I need to keep revising the model in order to get the allowed fan power right,
which does effect the system size due to the motor heat introduced into the air-stream, which in turn slightly alters the allowed fan power, on and on.<br>
<br>
Anyway, I think it will take me some time to become accustomed to this new form.<br>
<br>
Have a great weekend. <o:p></o:p></span></p>

<br>
Sorry if I gave the impression that I was offended. I was not. I am somewhat curt by nature. Too much time spent growling at my laptop instead of talking to people!<br>
<br>
You did bring up some good points. I usually develop a sort of matrix with all the baseline and proposed information (i.e. wall u-values, glazing u-values, etc) and submit that with my LEED model. I just find that the Table 1.4 Dec-2012 is much more involved
that the Table 1.4 Sept-2011 and am working on a project that I priced before this new table became effective, so like Pasha, I am somewhat taken back. I think filling out this table has added 3-4 days onto the project. For example, since my space areas
and those used by the electrical engineer differ and I need to add spaces together and apportion the LPD by percentages.<br>
<br>
I can understand the GBCI position that assembly performance rating needs to be calculated using the 90.1 Appendix A since eQuest does not always calculate accurate u-values when building an assembly using the materials in the library.<br>
<br>
One question that I would like to ask. I sometimes input a wall u-value using the Specification Method- Layers Input of say .064. Then when I look at the LV-D simulation report the u-value there does not match my input. For example on a current project,
in order to get the LV-D to report an exterior wall u-value of .064, I needed to tweak my exterior wall construction layers to be .066. Have you had this problem? Same for the vertical fenestration.<br>
<br>
Is it something I am doing wrong? Perhaps the Specification Method-Resistance is not correct?<br>
<br>
Anyway, you have a great weekend also.</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">I see you often on these lists and have a lot of respect for your knowledge. The information that you impart is of great value. And, I do agree that it takes significant time to fill out the
new 1.4 tables. My comments were not directed at you given your experience and technical expertise. For you and others like us, yes, we may see an increase in overall time charged to the modeling budget. But, alas, we are the minority here…</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">Given who was involved in these discussions this morning (and who these comments were directed at will remain anonymous), I could not resist commenting. For those modelers who do not take the
time to know what the standards require or what acceptable modeling protocols are or take the time to learn them, the new spreadsheets most likely will show modeling budget cost benefits and greater benefit to the project owners. Does it take more time to
fill out the new 1.4 tables and abide by the standards or have to respond to 10-12 reviewer comments and make the necessary revisions and hope that appeal won’t be necessary?</span><o:p></o:p></p>

number of comments needing to be addressed and fewer revisions required between review phases. It should also increase the chances of having a Preliminary model awarded in the Preliminary Review. That in the long run should result in savings for the modeling
budget, not cost more time and money just to fill out the form…</span><o:p></o:p></p>

I think he's referring to Table G3.1, No. 1.a for the Proposed model where it states that the simulation model of the proposed design shall be consistent with the design documents, including proper accounting of fenestration and opaque envelope types and areas.
<br>
<br>
I can't speak to the inconsistency on GBCI reviews. Was the U-value in this case particularly low? As for the comment itself, I think it simply speaks to the need to include the effects of thermal bridging in determining the overall U-value for the assembly.
Maybe you've already done this, in which case I would suggest you simply document your approach in your response.
<br>
<br>
I highly recommend checking out this paper published in 2011 which uses 3D heat flow modelling to calculate thermal transmittance through steel-framing, parapets, balconies, spandrels, etc.

>> Appendix G primarily provides very specific guidance for building the appropriate Baseline model to use as a benchmark to calculate the projected energy savings for your Proposed building as designed. Most of the guidance in Table G3.1 for the Proposed model
indicates it must be modeled as designed. This is where appendix A comes in for the Proposed constructions. U-values may only be calculated using the inverse of the sum of the R-values if each layer is continuous (e.g. uninterrupted by other materials such
as steel studs or joists). Appendix A provides tables with the effective U-values for various common heterogeneous constructions. Depending on the construction, the overall U-value for the assembly can vary significantly from the U-value calculated by summing
the U-value of the major components. The Appendix A assembly performance must be used for the Proposed constructions to accurately reflect performance of the building envelope. Hope this helps.<br>
