The purpose of these guidance notes is to help assist BREEAM assessors relate the contents of drainage reports to the ‘Surface water run-off’ and ‘Minimising watercourse pollution’ criteria in Pol 03. They do not cover the criteria for the ‘Flood resilience’.
We have published two separate Guidance Notes because there are small, but significant, differences between the criteria in the two schemes. This means that the Guidance Notes are not interchangeable;
GN15 can only be used for the assessment of BREEAM UK New Construction 2014.
GN38 can only be used for the assessment of BREEAM UK New Construction 2018.
Completing either template is optional. They are aids for demonstrating compliance and are not a requirement.
