Exposed wall Properties
Contains controls used to view and define properties for exposed wall surface types. Exposed wall surfaces are wall sections that are exposed to the outside of the building, directly in contact with the outside air. The exposed wall contains properties that all surface sub-types share as well as properties specific to the exposed wall sub-type.
The Properties For: Exposed wall dialog opens when the Exposed wall Project Tree object´s pop-up menu is activated in the OpenBuildings Energy Simulator Project Tree dialog box and the Properties menu item is selected.
Note: The
Exposed wall Construction details
properties panels under the Construction details heading contain controls used
to view the selected exposed wall construction details. The properties
displayed here are saved in the OpenBuildings Energy Simulator materials database’s constructions
definitions. Constructions can be viewed, manipulated and created using
controls and settings found on the
Materials
Manager
dialog.
Property heading | Properties |
---|---|
Category | Displays the surface category. Category is a read only property. |
Sub type | Used to view or change the surface Sub type from Exposed wall to another wall sub-type. The Sub type drop-down list is filtered and contains only wall and partition sub types. |
Name | Used to enter a name for the exposed wall. The name entered here appears appended to the exposed wall object on the OpenBuildings Energy Simulator Project Tree dialog box. |
Construction | Used to view of change the exposed wall material construction definition. |
Dimensions | Displays overall dimensions of the selected exposed
wall.
|
Heatflow | Contains controls used to view and set Heatflow data
for the exposed wall. Heatflow refers to the energy transfer occurring through
a surface’s material construction. Heatflow is established automatically as
rooms are created. OpenBuildings Energy Simulator determines if the adjacent space to
the room wall is in contact with another room. If no adjacent room is found
next the wall, the surface is defined as being of the surface sub-type exposed
wall.
|
Common | Displays common construction details for all
surface sub-types. Common construction details are read only properties.
|
External surface | Contains controls used to display thermal transfer
properties for external surface types such as the exposed wall. External
surface construction details are read only properties. External surface
construction details are defined using the controls in
Materials
Manager
.
|
Layers | Contains controls used to display the surface’s construction material layers in a read only table. The table displays thermal properties for each layer such as the thickness, density, conductivity, specific heat and vapor resistivity. |
