Perhaps I'm missing something, but didn't he ask us how to <b>calculate </b>the window to wall ratio? If I'm not missing something, we need to know specifically, is the wall number wall only or wall + glass. This level of information is shown on the LV-D report in eQUEST, if he's using eQUEST. That's why I said, "it depends".<br>

<p class="MsoNormal">ASHRAE 90.1-2007 Table G3.1 reads:<br>
"Vertical fenestration areas for new buildings and additions shall equal

I wasn't aware that this requirement had changed in the 2007 version (thanks

I can't find this section in Table 1.3.? I just find the 40% limitation for<br>
the baseline building. Can you post an excerpt?<br>

John,<br>
<br>
I'm assuming you are using ASHRAE 90.1-2007 Appendix G for your Baseline?<br>
If so, the way I read it from Table G3.1 is that you should evenly distribute<br>
the WWR of the entire building, not for each floor. Therefore I would use<br>
11.4% for each floor.<br>
<br>

<br>
I have a two story building. For the baseline I am evenly distributing
the<br>
fenestration.<br>
<br>
The first floor window area is 462.2 ft^2<br>
The second floor window area is 647.1 ft^2<br>
<br>
The first floor wall area is 4858 ft^2<br>
The second floor wall area is 4858 ft^2<br>
<br>
In the base line model do I use:<br>
<br>
First floor 9.5%<br>
Second floor 13.3%<br>
<br>
OR<br>
<br>
First floor 11.4%<br>
Second floor 11.4%<br>
