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.
ILP Guidance Note 1 updated - KBCN1385
Pol 04 references the ILP
Guidance notes for the reduction of obtrusive light 2011.
This has now been updated to the ILP
Guidance note 1 for the reduction of obtrusive light 2021.
This is available for free from the
ILP website.
Requirements
Table 2 of the guidance note classifies different lighting environments into Zones E0 to E4. Use this table to define which sets of requirements apply to the assessment.
Tables 3-8 of the guidance note define the requirements for criterion 2.
For cut-off type luminaires which (by design) block out light in obstructive directions, calculations are
not required for meeting requirements relating to:
- Vertical illuminance (Table 3), and
- Luminous intensity (Table 4).
This update will be reflected in the future revisions of the relevant manuals.
02-Nov-2021 Applicability to all UK BREEAM schemes confirmed.
27-Sep-2023 Updated for ILP Guidance Note 1 2021. Requirements clarified. Scheme applicability updated.
