This is because the BREEAM online tool detects a mismatch on the input file between the total building floor area the total sum of areas served by systems in the building.
To resolve selecting Building Compliance drop down menu in the software and then View Results Folder. Open the “buildingname_brukl.inp” file in Windows Notepad.
To correct this issue you need to take the total building area reported on the BRUKL minus the sum of the system areas. See the video below.
Note the total building area. In this example 400m2
Scroll down and find the Actual Building Systems, add the area of all of these systems together, in this example, 300m2.
The last system is "TYPE = No Heating or Cooling" and this is where the problem comes from. The area of this should equal the total Actual Building Area above (400m2) minus the sum of the Actual Building Systems (300m2) = 100m2. Do the same for the Notional Building then save the file.
Note that this issue does not affect Part L Compliance, it is only for users of the BREEAM online tool.
