Resize (Room)

Used to resize rooms and plenums by moving exposed walls, thus changing the shape of the room/plenum.

Accessed from:


  • Ribbon: Energy Simulator > Home > Rooms > Resize


Note: All movements are parallel to the selected wall’s original orientation. Resize maintains the relationships with adjacent rooms/plenums by not permitting movement of partitions.


SettingDescription
Inclusive Plenum When on, any ceiling or underfloor plenum in contact with the selected room are also resized. When off, plenums are not resized.

Effect In Specific Situations

Tool logic prevents removal of data with behaviors in specific situations:

Situation Effect
Chamfered corner When Resize room moves a wall that forms a chamfered corner (1), the tool prevents the removal of the chamfer wall. As the resized wall approaches the limits of the corner, the chamfer forming wall shrinks to a very small size (2). When resized wall moves past limit of the chamfer size, thus removing it, the tool issues a message "Invalid wall shape" in the Message Center (3).


Exposed wall changes to partition When Resize room moves a wall completely past another partially exposed wall, it changes the whole wall to a partition (1). The exposed wall can not be moved back to its previous location due to the new partition (2).


Effect On Other Building Objects

There are several behaviors with regard to other building objects in addition to the basic ones (exposed wall and partition) discussed previously:

Object Effect
Subsurface (Door/Window) If any portion of a window or door is intersected by the Resize room tool wall movement, it is deleted from the wall hierarchy.

Doors and windows can be moved and resized using Move Opening and by changing window and door dimension properties.

Virtual wall If any portion of a virtual wall is intersected by the Resize room tool, it is deleted from the room hierarchy.
Tilted wall Tilted walls (exposed walls) are extended/trimmed based on the exposed wall movements made with the Resize room tool.
Roof section Roof sections are not extended or trimmed when exposed wall movements made with the Resize room tool. This is because a roof does not necessarily have to follow the outline of the building. That is, there could be, by design, sections of a roof that overhang the building to cover or shade an entrance or courtyard.

However, when exposed walls are moved, the part of the wall that extends to the sloped part of the roof is maintained.

Internal ceiling, Exposed roof, Exposed floor Ceilings, exposed roofs and floors (internal and ground) are extended/trimmed based on the exposed wall movements made with the Resize room tool.
Fin If any portion of a fin is intersected by the Resize room tool wall movement, it is trimmed to that location.

If the wall movement is reversed (back towards its original location), the trimmed fine will remain trimmed to the previous location of the moved wall.

Surface component (Wall grille, Outlet, etc) If more than 50% of a surface component graphical element intersected by the Resize room tool wall movement, it is deleted from the wall hierarchy.

If 50% or less of a surface component graphical element intersected by the Resize room tool wall movement, it is not deleted from the wall hierarchy.
