The project is basically an existing 5-story warehouse with almost no windows. Part of the renovation is adding windows. The comment is as follows:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:red'>Table 1.4.1B indicates that the window-to-gross-wall ratio is identical in both cases; however it is unclear whether any fenestration was added or removed as part of the renovation. The baseline ratio must reflect the ratio as it existed prior to the renovation and the proposed ratio must reflect the ratio as it exists after the renovation. Revise the Baseline and/or Proposed cases as necessary so that the window-to-gross-wall ratio is accurately modeled and provide a revised prerequisite form and updated energy model output summaries as necessary. <o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I didn't think that this was the case - I thought that if you had an existing building, any EXISTING-TO-REMAIN windows would show up as the existing window type, but any NEW windows in the proposed alteration would be matched in the baseline model and comply with the Table 5.5 requirements. Meaning the WWR remained the 1:1 as long as it was < 40% glass.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I think this is just a matter of educating the reviewer on our building, but I wanted to make sure that there hadn't been a shift in how GBCI reviews existing buildings.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks!<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-family:"Arial","sans-serif";color:teal'>GHT Limited<br></span></b><b><span style='font-family:"Arial","sans-serif"'>James Hansen, P.E., LEED AP</span></b><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><br>Senior Associate<br>1010 N.
