Site clearance prior to purchase of the site - KBCN0916

For sites cleared prior to purchase of the site and less than five years before assessment, a Suitably Qualified Ecologist should estimate the site’s ecological value immediately prior to clearance using available desktop information (including aerial photography) and the landscape type/area surrounding the site. Where it is not possible for the ecologists to determine that the site was of low ecological value prior to the site clearance then the credits must be withheld, i.e. where there is no evidence and therefore justification for awarding the credits. For sites cleared more than five years ago, the ecological value of the site is to be based on the current situation on the basis that within five years, ecological features would have started to re-establish themselves and therefore act as an indicator of the site’s ecological value.

Sites with no invasive or diseased species - KBCN0847

Where invasive or diseased species are not present, credits are not automatically awarded for the 'Protecting against invasive or diseased species on site' criteria. This is because these credits intend to recognise developments using sites that are contaminated by invasive or diseased species. If these species are not present the aim of these credits are therefore not being met. This is part of the broader effort to encourage the use of contaminated land wherever possible, similar to the way credits are awarded for developments on sites that have been previously developed.

Suitably Qualified Ecologist – Other recognised organisations - KBCN0192

With regards to the definition of a Suitably Qualified Ecologist, in addition to the organisations already listed within the manual, full members of the following organisations are also deemed SQE's;

Royal Society of Biology
Institute of Environmental Sciences

Provided the individual meets all other requirements as outlined in the definition of a Suitably Qualified Ecologist (SQE).

Temporary ecological enhancements prior to development - KBCN00065

Where a site has been acquired but development is not scheduled to start immediately, it is possible to determine the baseline ecological value of the site at this point. Furthermore, to recognise where positive measures to enhance ecology have been taken to manage the site until development starts, these enhancement measures will not impact on the baseline value for the purposes of the BREEAM assessment, provided that the following have been met:

Following acquisition of the site and prior to any site clearance which involves the removal of any relevant features, the ecological value of a site is recorded in accordance with the relevant BREEAM methodology by a suitably qualified ecologist (SQE) to establish the baseline.
The SQE confirms and records details of the temporary ecological enhancement and management strategy being implemented on the site for the period prior to scheduled development.
For a period of up to 10 years, the initial baseline determined for the site is valid for the purposes of BREEAM assessment.
Any enhancements prior to scheduled development that are not being carried forward into the design, construction and operational phases can be disregarded for the purposes of establishing the baseline ecological value at development.
The assessment report shall provide documentary evidence of the above for certification.
Any enhancement and management practices implemented prior to scheduled development that will be maintained and continued through the design, construction and into the operational phase can contribute toward the awarding of credits via the BREEAM calculator tools.

Clarification: This guidance is currently under development. Please contact BRE Global with specific project details for confirmation of whether this approach may be used. The aim of these issues is to demonstrate the impact that a project has had on the site ecology, but comparing the site pre and post development. BREEAM does not want to penalise sites that have put in temporary ecological enhancements that enhance the ecology while waiting for development to begin.

Timing of Ecological survey/report - KBCN0292

If the ecologist's site survey and/or report is completed at a later stage than required, the assessor would need to be satisfied that it was produced early enough for the recommendations to influence the Concept Design/design brief stage and leads to a positive outcome in terms of protection and enhancement of site ecology.

‘Previously Developed Land’ clarifications - KBCN0757

Please see below clarifications related to crit 1 and the definition of 'Previously developed land' provided in the manual:

•‘Proposed development’ is defined as ‘Any new development (building, hard landscaping, car park and access roads) and temporary works (e.g. temporary offices/parking, material/machinery storage) that falls within the boundary of the assessed site.’

•Undeveloped areas of the site to be used for temporary works are not considered as ‘previously developed land’ unless they have been defined as ‘land of low ecological value’.
