Selection of a room displays the ‘Room settings’:
-
Include room(s) in analysis - is shown when a room is queried or selected whilst in VE Compliance allowing users to restrict analysis to part of the building only.
-
Room type - The Type of room attribute is normally set to ‘Heated or occupied room’, but the following alternative settings are provided to cover various types of unheated space:
-
Heated or occupied room - the usual designation, applying to all occupied spaces within the insulated building envelope (whether they are directly served by heating plant or not).
-
Unheated roof – use this type for an unheated roof space lying outside the insulated building envelope (i.e. where the insulation is at ceiling level).
-
Glazing cavity (required only rarely) – use this type for a glazing cavity that has been modelled as a separate room for simulation purposes.
-
Other buffer space – use this type for other types of unheated space attached to the building but lying outside the insulated building envelope. Examples are car parks and lean-to outbuildings.
-
Internal void or warm roof – use this type for floor and ceiling voids, and for roof spaces that lie inside the insulated building envelope (i.e. with insulation at rafter level).
-
Building area type - The settings NCM Building area type and NCM Activity together specify the activity assigned to the room for the compliance analysis, which in turn (via the NCM Template) sets the standard conditions applied for occupancy and plant operation. For example, a room assigned the activity ‘Open plan office’ in a building of type ‘Office’ has an NCM Template called ‘NCM Office: Office (Office: Open)’. This contains the occupancy and equipment gains, the lighting level and profile, the room conditioning settings and the minimum ventilation regime laid down as standard for NCM assessments of an open plan office.
