<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>As of TRACE 6.2.3, there is an active chilled beam system type
available, though I have yet to test it out. Theoretically you could model a four-pipe
active chilled beam and set the main and auxiliary cooling coil capacities to
zero while inputting the desired heating capacities (see the help file). The
DOAS is modeled via the 'dedicated OA' tab and under the 'options' tab there is
location to select the enthalpy wheel. TRACE doesn't support biomass boilers
but depending on what information you need you could approximate the behavior.
