<div style="font-family:times new roman, new york, times, serif;font-size:10pt;">Shiela:<br><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.<br><div> </div><div> </div>Paul Diglio, CEM, CBCP<br><br><div>87 Fairmont Avenue<br>New Haven, CT 06513<br>203-415-0082</div><br><br><div><span><a target="_blank" href="http://www.pdigliollc.com">www.pdigliollc.com</a></span><div><br></div><div style="font-family:times new roman, new york, times, serif;font-size:10pt;"><br><div style="font-family:times new roman, new york, times,

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></p><p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D;"> </span></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></p><p class="MsoNormal"><span style="font-size:11.0pt;

<br>>> 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.
