When a building has been specified as shell and core (checkbox option on Building and System Data) then a BRUKL Compliance Report will show this at the top of the page and results are only shown for rooms that have been marked as Core (see Building Regs tab of Room data).
There are some cases as specified in the NCM Modelling Guide where these settings are ignored:
1. if the project Stage of Analysis (Building and System Data) has been set to As Designed
2. If the assessment run is an EPC rather than a Compliance simulation
