<p class="MsoNormal">While ASHRAE’s guidance sets a “floor” for the “minimum resolution” of detail for your zone geometries, that minimum is most likely to be set by the proposed case system(s) as the baseline case should match the proposed, so I would start
there. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With such a large project – it will be advantageous to be relatively “aggressive” in combining zones/spaces with similar load profiles. Consider also whether it may be advantageous to utilize shell/floor multipliers.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Consider also that the wizards have some built-in capacity to help you create “combined occupancy” zones through the optional zone allocation screens for each shell. You can for example specify that a given floor/shell’s “Core” zone is
60% open office, 20% corridors, and 10% mechanical/electrical rooms, and the wizards will generate interior load profiles, occupancy densities, etc. unique to that shell. Utilizing this feature is another option in your toolbox to consider.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Probably also worth noting there are some (simple) illustrations in the 90.1 user’s manual to illustrate the minimum resolution of zoning as prescribed in appendix G. It’s quite similar to the “core/perimeter” zoning as the wizards will
generate with relatively simple shell floor plates.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best of luck!<o:p></o:p></p>

<p class="MsoNormal">Hi everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am working in a very large building, which has many different space usage types.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The HVAC Project consists in a lot of AHUs, constant volume, fan coil units and active chilled beams.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The issue is that there are almost 1500 spaces distributed in the different systems.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am a little disoriented because I started modeling my Project Building with each one of the AHUs without discriminating each space, but this AHUs attend different space usage types, for instance, one of them is for the “Pharmacy”, and
it attends circulation, office spaces and storage.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">According to the number of floors, building area and heating source, my Baseline HVAC system will be System 7, Variable air volume with reheat. So I will assign one VAV AHU for each floor. And then, how will I assign each VAV zone?, do
I have to model all the 1500 spaces or will it be enough to model a VAV box for each AHU as defined in the Project Building?,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I will really appreciate your comments on this,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you,<o:p></o:p></p>
