District cooling – Used in combination with local cooling - KBCN1634

Where district cooling can be considered outside the scope of the assessment, either in accordance with the Methodology section of the technical manual or in line with KBCN0759, compliance must be based on calculating the DELC for all systems. However, where the district cooling system is exempt from assessment, as described above, this should be based on a GWP of zero for the district cooling system.
