ASHRAE 90.1 allow spaces of similar thermal characteristics to be combined in
thermal blocks. I do not include what you call support spaces because the
load and occupancy is much different than, say a classroom. I would
define the corridor as a separate zone within the thermal block but served by
the same HVAC system. This allows you to have a different set-point,
airflow, occupancy and schedules for the corridor.<br>
<br>
You do not have to define a separate shell for each block, you can define the
block by custom zones in the wizard.<br>
<br>
I divide up a thermal block into as many reasonable zones as possible.
This allows me to find out which area of the thermal block is causing any unmet
heating or cooling hours. It also allows me to change the HVAC system
control zone to that zone which is the hardest to satisfy in the summer and
winter. These zones can be served by a single HVAC system.<br>
<br>
For a proposed model that needs to conform to an actual design, defining
multiple zones per thermal block allows you to balance the airflow to zones
that have unmet hours without increasing the overall airflow of the HVAC
system. I define the zonal airflow in the Zone tab. I reduce the
airflow to the zones without any unmet hours and increase the airflow to those
zones that have unmet hours. I do not define the total fan CFM in the
Airside Systems tab.<br>
<br>
