<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I
have a project that is classified as low-rise residential. It will use a
2-pipe fan coil system and will get its ventilation from operable
windows. Does anyone have suggestions on how to model this? I tried
to use the Natural ventilation tab but it does not activate for fan coil units
and I do not know how to get natural ventilation and a chilled water system to
work together. <o:p></o:p></span></p>

<div>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I
am assuming that when it comes to cooling and heating that I just put the OA
requirement for the room in the system and it will be the same thing as getting
it through the window. Correct? However I do not know how to
account for someone opening the window to supplement the cooling and
heating. Should I model an air-side economizer and just let that take
care of any "free-cooling"? Does anyone have any suggestions or
tips?<o:p></o:p></span></p>
