The mechanical rooms in a project I'm dealing with have freeze protection heating only but as per LEED spaces that are heating or cooling only have to be modeled as both heating and cooling. For example, one of the mechanical rooms has 8000 CFM of exhaust and zero Outside Air CFM. How does one model for accurate representation yet keep the loads from ballooning disproportionately in such a situation?<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal>Thanks,<o:p></o:p></p></div><div><p class=MsoNormal>Ramana Koti.<o:p></o:p></p></div></div><P align=left><FONT size=2><FONT face=Tahoma><FONT color=#0000ff>
