According to the energy cost budget method each system should be mapped one-to-one on figure 11.5.2. The fan coils will be mapped as system 8 (heat pump), but I am not sure how to map the dedicated outside air system, I thought to model it identical to the proposed building, but that means a chiller needs to be added to the baseline model which does not make sense to me. I thought of using only system 8 for conditioning and providing the outside air to the guest rooms, but the energy cost budget requires to model the secondary heating source identical to the proposed model so I am not sure how to separate the heating source for outside air from the space heating. Any thoughts on how to model the baseline?<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Thank you,<o:p></o:p></p></div><p class=MsoNormal>_______________________________________________<br>Bldg-sim mailing list<br><a href="http://lists.onebuilding.org/listinfo.cgi/bldg-sim-onebuilding.org">http://lists.onebuilding.org/listinfo.cgi/bldg-sim-onebuilding.org</a><br>To unsubscribe from this mailing list send a blank message to <a href="mailto:BLDG-SIM-UNSUBSCRIBE@ONEBUILDING.ORG">BLDG-SIM-UNSUBSCRIBE@ONEBUILDING.ORG</a><o:p></o:p></p></div></div></body></html>
