Customize Analytical Spaces with Revit 2022

Hello all,

 

I am beginning with Systems Analysis with Revit 2022 to simulate HAVC loads. I separated the floor plan into several spaces (grids) with the space separator as shown in the first screenshot below. I would like to know the required cooling and heating loads within each small space.

 

However, the analytical spaces in the energy model are not identical to the spaces I separated. Some spaces are combined forming an analytical space as shown in the second screenshot below.

 

So, is there any method to let Revit generate analytical spaces as same as the spaces I divided with space separator?

 

The rvt file is attached. Thanks a lot for your help.

It doesn't look like you have created HVAC Zones

 

  1. First you define spaces' boundaries (that grid which you have created)
  2. Then add the spaces in each cell of 9x12 Grid (could be more convenient to split/divide large open spaces for purposes of sizing and loading)
  3. After you define spaces >>> you assign them to HVAC Zones

  4. You can edit zones by selecting and the zone and from the ribbon use EDIT ZONE (then add remove spaces to it as necessary)
  5. Regenerate the Energy Model

Typically a zone will match a room, or be part of a room. Why would you create so many spaces in what appears to be one room? The only time I split a room in multiple spaces is if those areas are used differently and require different treatment. But this is mainly for Lighting calcs (also spaces used for that). For HVAC, we assume one room has the same conditions.
