This will not work. When using a single zone system (whether it be PSZ or SZRH) you specify a control zone. This control zone tells the unit what temperature to supply the air at. If you put two conditioned zones on one single zone system the non-control zone will be subject to the whims of the control zone. Hence the large amount of unmet load hours in E5 NNW Perim Zn (G.NNW1). Either combine the zones into one zone (Really it is one zone even if there is a wall separating them) or if there are some other reason why they can control the supply air temp independently you will need to select a different system type or create two systems. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:blue'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:blue'>Tim.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:blue'><o:p> </o:p></span></p><div><div><p class=MsoNormal><b><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:black'>Timothy Howe, MS, LEEDŽ AP BD+C</span></b><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:black'><br>Mechanical Engineer<br>Stantec<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:gray'>61 Commercial Street<br>Rochester NY 14614<br>Ph: (585) 413-5347<br>Fx: (585) 272-1814<br>Cell: (585) 330-8681<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial Narrow","sans-serif";color:blue'><a href="http://www.stantec.com"><b><span style='color:#993333;text-decoration:none'>stantec</span></b><span style='color:#003F6E;text-decoration:none'>.com</span></a> <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:black'>The content of this email is the confidential property of Stantec and should not be copied, modified, retransmitted, or used for any purpose except with Stantec's written authorization.
