<p class=MsoNormal><b><font size=2 color=navy face=Arial><span lang=EN-US

to ASHRAE 90.1, as hotel belongs to residential building, I have to choose PTAC
as my baseline HVAC system.<o:p></o:p></span></font></b></p>
<p class=MsoNormal><b><font size=2 color=navy face=Arial><span lang=EN-US

selected DX coil as the cooling source and hot water coil as the heating

<p class=MsoNormal><b><font size=2 color=navy face=Arial><span lang=EN-US

4 system type for me to choose, including Packaged VAV with HW reheat, Packaged
Multizone with HW heat and Packaged DX Series or Parallel Fan-Powered VAV with
HW reheat.<o:p></o:p></span></font></b></p>
<p class=MsoNormal><b><font size=2 color=navy face=Arial><span lang=EN-US

suitable to select packaged multizone as the baseline system for the hotel
building?<o:p></o:p></span></font></b></p>
<p class=MsoNormal><b><font size=2 color=navy face=Arial><span lang=EN-US
style='font-size:10.0pt;font-family:Arial;color:navy;font-weight:bold'>Because after
I compared the energy consumption for the baseline and design building which
employs 4-pipe FCU as the HVAC system, there seems to be a great energy saving….<o:p></o:p></span></font></b></p>
<p class=MsoNormal><b><font size=2 color=navy face=Arial><span lang=EN-US

know if the system chosen for the baseline building is wrong or not.<o:p></o:p></span></font></b></p>
<p class=MsoNormal><b><font size=2 color=navy face=Arial><span lang=EN-US
style='font-size:10.0pt;font-family:Arial;color:navy;font-weight:bold'>Besides,
is it really the case that hotel can meet the basic requirement of 14% energy
reduction easily? Is FCU much more effective than PTAC?<o:p></o:p></span></font></b></p>
