<DIV><FONT face=Arial color=#000000 size=2>I searched thru the archives but couldn't fiind an answer to this. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Why is there a direct conflict in the required Baseline system type between the App G chart in 90.1 and the wording in the 90.1 user manual?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have a 6-story building that is 100,000 sq ft. If I read Table G3.1.1A of 90.1, it says:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>"Nonresidential & More than 5 floors OR > 150,000 sq ft", that I should use System 8 (VAV with PFP boxes).</STRONG></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Even Table G-A in the User Manual says the same thing.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In addition, the requirements for using System 6 say:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>"Non residential, 4 or 5 floors or less than 75,000 sq ft OR 5 floors or less and 75,000 - 150,000 sq ft".</STRONG></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Both of these facts would lead me to believe that anything over 5 stories should be System 8. However, the wording in the User Manual goes on to say that:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>"For intermediate-sized buildings that are 4 or 5 floors and less than 75,000 sq ft or <U>more than 5 floors and between 75,000 and 150,000 sq ft</U>, the baseline building HVAC system for electric heat is packaged VAV system."</STRONG></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've finished modeling the Baseline building with System 8, but now that I've read the User Manual, it would appear that I am supposed to use PVAV. I really hope I don't have to go back and change the baseline system again.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any thoughts?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
