Single Construction Walls
These constructions will be applied to exterior wall surfaces in the building drawing process. The single construction wall detail screen will display the layers that have been added to the construction type in order from outside to inside. “Outside” is the layer furthest away from the zone air. “Inside” is the layer next to the zone air. The screen will also display the opaque constructions calculated values.
-
All opaque constructions (except for c-factor walls, f-factor floors, and multiple construction walls) give you the ability to define the u-value for the construction in the Templates section of the project. This override will be used instead of the calculated u-value obtained from using the defined material layers. To override the calculated u-value, change the “Override u-value” field and enter your desired U-factor. Note, because the EnergyPlus™ engine calculates the assembly u-value, TRACE® 3D Plus will modify the material layers until the defined user override u-value is obtained.
-
When editing a single construction wall library member, you can add layers by hitting the + Add layer button. This will bring up a list of the valid Opaque Material library members. Hitting the + button next to a material library member will add it to the construction as a layer. The opaque constructions calculated values will be updated when a new material is added or deleted from the construction layers.
-
You can switch the library member of an existing layer by selecting the replace layer button. Layers can be moved up or down with the buttons or you can delete a layer by hitting the trash can button.
-
Single construction walls can also have a radiant layer. This layer is only used when a radiant system has been selected in the project file. It will add or remove heat to the zone via the construction. To add a radiant layer to the wall construction, move to the radiant layer tab and add the required radiant layer information.
