Step 4. Set building type and general data

At this stage you may wish to go to VE Compliance and set up some of the high-level data required for the compliance analysis.

Firstly, check that the Regulatory framework (‘Regs’) selector is set to ‘Part L2 (2021) – England’ or ‘Part L2 (2022) – Wales’.

In the ‘Building settings’ box near the bottom of the screen select a building type from the list. This indicates the type of building for ratings purposes and determines what room function/activity can be specified in the building and applied to individual rooms. The glazing area is determined by the activity and whether it is side-lit, top-lit or unlit.

For a building with multiple use, the various parts can be analysed by including NCM activities from other NCM building types in the room-level assignments. This can be done for individual rooms, groups of rooms (using Edit Group Attributes) or via Tabular Room editing.

Not all zones may need to be included in a compliance run for example separate buildings may exist within the same model. The part(s) of the building included in a particular analysis is defined by the settings of the check boxes ‘Include room in Building Regs analysis?’ for each room on the Room Data Building Regulations tab.
