Aircraft safety – developments in the proximity of airports - KBCN0912

Where it can be demonstrated that an assessed development, within or adjacent to an airport or similar, must restrict the ecological value of the site for reasons of aircraft safety (mitigating the risk of bird-strikes to meet local or national regulations), the approach for some issues in the Land Use and Ecology category can be adjusted. If in these circumstances, the client wishes to enhance ecological value on an external site, outside of the main development site, this can be considered in the following way for each issue: Site selection: The development site only must be assessed. Ecological value of site and protection of ecological features: The development site only must be assessed, but the recommendations may be tailored to suit the requirements of the relevant legislation. Enhancing site ecology: The development site and the external site must be included in the SQE’s report and recommendations, albeit that, for the development site, the approach may to be to restrict biodiversity. Enhancements implemented in-line with the recommendations of the SQE are likely to apply to the external site. Long term impact on biodiversity: Both sites must be considered in the SQE’s report to meet the prerequisite/first credit as applicable, albeit that, for the development site, the approach may to be to restrict biodiversity. Further credits in relation to improving and maintaining the site’s long-term biodiversity can be awarded on the basis of adopting these for the external site only, in line with the guidance.

Measures for protecting features of ecological value - KBCN0583

Where the actions outlined in CN 'Protecting features of ecological value' are deemed not appropriate for a particular site, by a suitably qualified ecologist (SQE), it would be acceptable for alternative means of protection to be used where recommended by an SQE. Where alternative approaches are being used, the assessor must ensure that adequate evidence is collated to demonstrate the ecologists recommendations have been implemented, this should include clear photographic evidence of the solution implemented. This is to ensure that professional expertise is applied to appropriately address specific scenarios.

Risk to Ecologist’s safety - KBCN0704

In some situations a significant safety risk may prevent a suitably qualified ecologist from attending the site to undertake a site survey. In these cases a desktop study can be used to demonstrate compliance, where the ecologist confirms that it is an acceptably robust substitute. In these cases, the assessor must provide evidence to confirm the type of significant safety risk present.

Shared ecological enhancements - KBCN0656

A site-wide approach to ecological enhancements can be used on sites where multiple buildings share areas of soft landscaping. The enhancement benefits are applied to the individual building assessments within the site. Similarly, where a building comprises more than one assessment, eg different floor assessments, a green roof on top of that building can be used to award credits for each assessment for which the Land use and ecology issues apply. The benefit can be applied on a site-wide basis provided all developments are completed within the appropriate timeframe of a valid ecological survey.

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.

Verification of an ecology report / information - KBCN1192

If the appointed ecologist does not meet the definition of a ‘suitably qualified ecologist’ (SQE) the report / information submitted to support the assessment must be verified by an individual who does. 1. The individual verifying the report must provide written confirmation that they comply with the definition of a ‘suitably qualified ecologist’. 2. The verifier must provide signed confirmation that they have checked and approved the report. This must clearly reference the report and can be in the form of a signed letter or their printed name and signature on a completed pro-forma. In doing so, they are deemed to confirm that the report: a. represents sound industry practice b. is correctly, truthful, and objective c. is appropriate given the local site conditions and scope of works proposed d. avoids invalid, biased, or exaggerated statements Such confirmation from the verifier must be provided in addition to all other information required by the relevant technical manual and referenced as part of the evidence submitted to demonstrate compliance. It can take a number of years for an ecologist to meet the SQE definition. Verification of information by an existing SQE supports the practical application of the assessment criteria and is in line with industry practice.
