Properties For: Internal ceiling
Contains controls used to view and define properties for internal ceiling surface types. Internal ceiling surfaces are ceilings inside rooms that are adjacent to inside spaces (rooms) above. The internal ceiling contains properties that all surface sub-types share as well as properties specific to the internal ceiling sub-type.
Opens when the Surfaces > Internal ceiling: object´s pop-up menu is activated in the AECOsim Energy Simulator Project Tree dialog box and the Properties menu item is selected.
Internal ceiling Construction detailsThe properties panels under the Construction details heading contain controls used to view the selected internal ceiling construction details. The properties displayed here are saved in the AECOsim Energy Simulator materials database’s constructions definitions. Constructions can be viewed, manipulated and created using controls and settings found on the Materials Manager.Setting | Description |
---|---|
Category | Displays the surface category. Category is a read only property. |
Sub type | Used to view or change the surface Sub type from Internal ceiling to another ceiling or roof sub-type. The Sub type drop-down list is filtered and contains only ceiling and roof sub types. |
Name | Used to enter a name for the internal ceiling. The name entered here appears appended to the internal ceiling object on the project tree. |
Construction | Used to view of change the internal ceiling material construction definition. |
Dimensions | Displays overall dimensions of the selected
internal ceiling.
|
View factor to ground | Automatically calculated by default (Calculate view factor to ground is checked). The auto-calculated value assumes horizontal ground. If the ground slopes significantly upward or downward as you move away from the building, the auto-calculated view factor to ground could be incorrect. |
Calculate view factor to ground | When on,
View factor to ground is automatically
calculated. Use this option when the ground is horizontal.
When off, the value for View factor to ground is entered manually. Use this option when the ground slopes significantly. |
Heatflow | Contains controls used to view and set Heatflow data
for the internal ceiling. Heatflow refers to the energy transfer occurring
through a surface’s material construction. Heatflow is established
automatically as rooms are created. AECOsim Energy Simulator determines if the adjacent space
above the room ceiling is in contact with another room above. If an adjacent
room is found above the ceiling, the surface is defined as being of the surface
sub-type internal ceiling.
|
Common | Displays common construction details for all
surface sub-types. Common construction details are read only properties.
|
Internal surface | Contains controls used to display thermal transfer
properties for internal surface types such as the internal ceiling. Internal
surface construction details are read only properties. Internal surface
construction details are defined using the controls on
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. |
Simulation Reports |
Note: The two face
temperature output variables can be selected for any surface that is included
in the project (exposed walls, exposed roofs, ground floor, partitions,
windows, etc.).
Note: The two solar
radiation output variables can be selected for
"exposed" surfaces (exposed to outdoors).
Incident solar radiation can be selected
for any surface that is exposed to outdoors (e.g., exposed wall, exposed roof).
Transmitted solar radiation only applies
to windows that are located in surfaces that are exposed to outdoors. These
options are disabled for interior partitions or interior windows.

Notifications panel | Used to validate project data and resolve issues with project data in real time (as it is being entered in the Properties For: dialogs) via errors, warnings and messages. |
