Classes, Categories & Columns

 

Constructions are divided into classes with different thermal property sets. There are two thermal classes – Opaque and Glazed. If particular cost planning and life cycle software is licensed, there are two other non-thermal classes – Hard landscape and Misc. In the case of opaque constructions thermal capacity, as defined by density and specific heat capacity, is important. Glazed constructions, by contrast, are to a good approximation massless, but they require properties characterizing their solar transmission properties. Hard landscape and Misc. constructions have similar properties to Opaque constructions plus some specific extra properties.

 

The classes of construction are further broken down into categories, as follows:

Opaque constructions:

·       External Wall

·       TSC Wall

·       Internal Partition

·       Ground/Exposed Floor

·       Roof

·       Active Thermal Roof

·       Internal Ceiling/Floor

·       Active Thermal Ceiling/Floor

·       Door

 

Glazed constructions:

·       External Window

·       Internal Window

·       Roof Light

 

Hard landscape constructions:

·       Pavement/sidewalk (private)

·       Site hard landscape

·       Site parking

·       Site pervious hard landscape

·       Site road

 

Misc. constructions:

·       Double facade

·       Foundation

·       Gutter

·       Shape beam

·       Shape column

·       Shape lintol

·       Shape stairs

·       Solid beam

·       Solid column

·       Solid lintol

·       Solid stairs

·       Structural frame

 

The construction categories in the Opaque and Glazed classes correspond to categories of building element used for construction assignment in the Apache View. The thermal parameter sets for constructions are broadly similar for categories belonging to the same class (Opaque or Glazed), but in some cases differ in respect of their Building Regulations parameters and default values for surface resistance.

Tabs on the tabular edit grid are arranged to give access to the following:

 

Tabs for constructions in the Opaque class - separate tabs for each category:

·       External Wall – Opaque class, Wall category

·       TSC Wall – Opaque class, Wall category

·       Partition – Opaque class, Partition category

·       Ground floor – Opaque class, Ground floor category

·       Roof – Opaque class, Roof category

·       Active Thermal Roof – Opaque class, Roof category

·       Internal Ceiling/Floor – Opaque class, Internal Ceiling/Floor category

·       Active Thermal Ceiling/Floor – Opaque class, Internal Ceiling/Floor category

·       Door – Opaque class, Door category

 

Tabs for constructions in the other classes - single tabs covering all categories in the class:

·       Glazed – Glazed class, all categories

·       Hard landscape – Hard landscape class, all categories

·       Misc. – Misc. class, all categories

 

Tabs for constructions in any class or category:

·       Assigned (thermal) shows constructions that are assigned to thermally active elements in the model.

·       Assigned (non-thermal) shows constructions that are assigned to thermally inactive elements in the model.

·       Costs/LCA shows only those constructions that have Data source BRE Impact, with extra columns showing the data related to costing and life cycle analysis.

·       UK Part L shows only those constructions that have Data source UK NCM – this shows all constructions that have been automatically added from UK NCM templates for use in UK Part L analysis.

 

NB this document describes the default tab status and dialog size. As with other tabular edit dialogs the tabs, columns and filtering can be customized and the dialog can be resized. These changes are saved between sessions for your particular Windows username.

 

  Project construction columns

Within each tab a list of project constructions is displayed, with the following columns of summary information:

 

To edit a construction, double-click the grid row on the ID cell. Alternatively select the construction and then use one of four Edit construction options (the button, the side panel option, the main menu option or the context menu option).
