Zoning Strategy - One Zone per Room

What is one Zone per Room? 

A one zone per room model means the model is broken into custom thermal zones, defined as "rooms" by the user. In SketchUp, the rooms are created by any line intersecting a floor plate. In Revit, Revit rooms are used to define the zone.

Where Sefaira uses one zone per floor

  • Plugin - Default setting
  • Web Application - Optional setting

How results will be affected 

Although Sefaira adds partitions between rooms, these are currently adiabatic in both "one zone per room" and "perimeter/core" zoning. This means there are no major changes in the detail of internal mass or heat transfer. Therefore, the sizing and energy results will not necessarily change only by changing the zoning methodology. The changes come by being able to more accurately assign space uses within the zoning tab or better understand gains/losses of a specific zone in the peak loads tab instead, as examples, instead of averaging over an entire cardinal direction or floor. 

What are the benefits of using one zone per floor? 

We recommend one zone per room for models where perimeter core zoning is not able to be applied due to constraints with the floor plate shape.

It can also be used to create things like core zones or to differentiate space types within the building (eg. living, bedroom or open plan office and meeting room).
