To recognise and encourage the use of robust and appropriate life cycle assessment tools and consequently the specification of construction materials with a low environmental impact (including embodied carbon) over the full life cycle of the building.
The following is required to demonstrate compliance:
| 1 | The project uses a life cycle assessment (LCALife Cycle Assessment) tool to measure the life cycle environmental impact of the building elements. |
| 2 | The LCA includes at least the mandatory building elements indicated in the 'Materials assessment scope' section of the BREEAM International Mat 01 calculator (where present in the building). |
| 3 | The mandatory requirements identified in the 'Materials assessment tool, method and data' section of the BREEAM International Mat 01 calculator have been met. |
| 4 | A member of the project team completes the BREEAM International Mat 01 calculator and determines a score based on the robustness of the LCA tool used and the scope of the assessment in terms of the elements considered. Credits are awarded as follows: |

| 5 | Where a range of at least five products specified at Design Stage (DSDesign Stage) and installed by Post-Construction Stage (PCS Post-Construction Stage) are covered by verified EPDEnvironmental Product Declaration (see CN3.2). |
| 6 | The requirements for exemplary level criteria outlined in Table 41 within the assessment criteria above have been achieved. |
| 7 | Where a range of at least 10 products specified at DS and installed by Post-Construction Stage (PCS) are covered by verified manufacturer specific EPD (see CN3.2). |

CN1 | Applicable assessment criteria | Both options: All criteria relevant to the building type and function apply. Refer to Appendix D – Shell and core project assessments for a more detailed description of the shell and core assessment options. |

CN2 | Applicable assessment criteria - Single and multiple dwellings | Both options: All criteria relevant to the building type and function apply. Refer to Appendix E – Applicability of BREEAM New Construction to single and multiple dwellings, partially and fully fitted for a more detailed description of residential assessment options. |

CN3 | Element not specified (applicable elements) | In some buildings, not all elements listed within the BREEAM International Mat 01 calculator will be present or specified, e.g. upper floors in single storey buildings. In these instances the calculator will re-evaluate the standard and exemplary level benchmarks according to the applicable elements. |
CN3.1 | LCA tool approvals | Where a project team is considering using a LCA tool which has not been previously evaluated by BRE Global (BREG), the assessor should contact BREG providing all information required for the evaluation of the tool. The evaluation process of LCA tools often requires the involvement and issue of evidence by the tool producer or developer. The evaluation process can take up to four weeks; therefore assessors are advised to contact BREG as soon as possible to initiate the process. The fee sheet available on the assessor extranet provides details of fees for LCA tool evaluations. All tools (and versions of tools) used must:
The BREEAM International Mat 01 calculator provides a list of previously submitted tools (by version) and their associated evaluation score. |
| Environmental Product Declarations (EPD) Classifications | Each EPD shall be classified according to Mat 03 Responsible sourcing of construction products : Table 44 . For each EPD, select the classification that is the closest match. Only two EPDs per classification group may be counted. This is to encourage a range of EPDs from different construction product sectors. Where a product is comprised of more than one material, the assessor should decide which material category classification should be used at their own discretion. EPD certificates must be valid (unexpired) at the point of specification. The EPD must be compliant with ISO 14025, ISO 21930 or EN 15804. | |

This issue is concerned with the use of LCA on the project, and robustness of the method or tools used. At present, we do not seek to benchmark performance. This is likely to be included as LCA matures and BRE Global have collated enough building performance data to establish robust benchmarks.
The Mat 01 Calculator scores points based on the rigour of the life cycle assessment in terms of:
Note: Aside from the likely benefit to the environment from teams using LCA tools, the objective for BREEAM is to gather LCA performance data in order to create benchmarks and inform future updates of the scheme. The evidence requirements below are generic, but BRE Global understand that some tools are not able to fulfil all of the criteria. Where this is the case, the tool operator should submit results as close as possible to that required for the tool.
A copy of the full IMPACT project or building file submitted by the assessor to BRE Global must be transmitted in the following format:
An electronic data table or tables of results (suitably cross referenced) generated by the tool, submitted by the assessor to BRE Global must fulfil the following criteria:
Submission of information to BRE Global for the purpose of assessing this issue will be deemed to grant permission for the BRE Group of companies to use the information to:
