Overview

If Criterion 2 of the Compliance report is showing a different overall air permeability figure to the one you believe you should be getting, it may be that you have left your room definition set to 'default' rather than individual when setting up the data.

Method

The Room Data tab in PartL is used to set up data sets for your room. These can either be a default set for multiple room definitions, or individual sets for specific zones.

When you visit the Room Data tab, it will always default to showing you the Default data set. This doesn't mean that any particular zones are set to use this data. This is just allowing you to view the Default data set.

If you click into "Individual room data" and select a room, again, this doesn't mean that the room is set to the individual room data set, but is allowing you to view any individual data sets that may be defined.

To fix a data set to a room, you should consider the "Use default" tick box. This option only becomes active when you are in "Individual room data" mode. If the "Use default" box is ticked, then the room will be set to use the Default data. If "Use default" is un-ticked, then the room will be using the individual room data that is displayed.

The air permeability figure on the output document represent the overall average based on the floor area.

For e.g.

Consider 3 rooms, each with a floor area of 5m²

Room01 and Room02 are set to use default room data with an air permeability of 10m³/(h·m²)

Room03 uses individual room data with an air permeability of 8m³/(h·m²)

The compliance report would show a total air permeability of 9.33m³/(h·m²)

Buildings below 500m² of useful floor area can be exempt from a pressure test. In these instances a separate submission may be required to justify not completing a pressure test, and to confirm the air permeability used in the BER calculation is taken as 15m³/(h·m²) at 50pa.
