<p style="MARGIN: 0cm 0cm 0pt" class="MsoNormal"><font size="3" face="Times New Roman">The ‘best case scenario’ is to match the room-by-room peak occupancy numbers with the total building ones by adjusting hourly schedules which would be fairly complicated to ensure the total building occupants can be distributed in different rooms but remain the same all the time.</font></p>

<p style="MARGIN: 0cm 0cm 0pt" class="MsoNormal"><font size="3" face="Times New Roman">In reality, the objectives of estimating either room-by-room peak numbers or overall building numbers vary according to disciplines. Architects may have concerns over spatial constrain while mechanical engineers will worry about system size, peak loads and energy requirements. When it comes to modeling, my understanding is to see the issue mainly from mechanical design point of view: </font></p>

Managing to ask mechanical designers to verify the numbers provided by architects and running the load calculation with respect to these numbers. </font></li>

Architects or building owners may have better idea of how many they would be and there is little room to change the figures by engineers. Running energy simulation with respect to these numbers. Scale the room-by-room numbers down to match the overall building numbers is acceptable at this point. <span style="mso-spacerun: yes"> </span><span style="mso-spacerun: yes"> </span><span style="mso-spacerun: yes"> </span><span style="mso-spacerun: yes"> </span></font></font></li>
