More than one system providing the same building service - KBCN1908
Where different systems provide the same building service to different areas of the building, the characteristics of the system that serves the highest proportion of the building's floor area must be assessed. For example, if there are two electrical space heating systems serving the same building, only the system supplying the larger floor area must be assessed for compliance.
