Mat 02 - Environmental impacts from construction products - Environmental Product Declarations

Information correct as of 13thDecember 2024. Please see kb.breeam.com for the latest compliance information.

Definition of a ‘product’ - KBCN1142

For Mat 02, the definition of a product is the same as for Mat 03: ‘A manufacturer-specific product (i.e. with a manufacturer reference number) that is specified by the designer (e.g. architect, engineer, interior designer, quantity surveyor, landscape architect etc.) or selected by the constructor (principle or sub-contractor), and installed on the project’. It is acceptable for a product in Mat 02 to have variations in where it is manufactured, how it is manufactured and the source of its constituent products (as defined in Mat 03), providing these variations are not available for the specifier (or constructor) to choose between, but are instead determined by the manufacturer. If variations are available for the specifier to choose between then, for the purposes of Mat 02, each variation is effectively a different product. Examples of acceptable variations for a product:- Examples of unacceptable variations for a product:- The following exceptions are variations that the specifier can choose between, but shall still be considered a product for the purposes of Mat 02 (providing they are variations of a single product and not listed as separate products by the manufacturer). This is to recognise the practicalities of producing EPD for product ranges with varying combinations:-

EPD for systems of products always installed together - KBCN1102

Where an EPD is for a system of products, from the same manufacturer, that are always installed together, this system of products shall be considered a single product for the purposes of assessment in BREEAM. Examples of this include:

EPDs’ validity - KBCN0798

EPDs which have expired or are pending verification at the time the relevant product was specified, cannot contribute to awarding credits. However, it is not necessary that they are valid at the time of the design or post-construction stage submissions. BREEAM is primarily trying to encourage designers to take EPDs into consideration when specifying products.  
04/11/2019 Confirmed applicability to UK NC2018
27/03/2020 Added applicability to Green Guide ratings and ISO 14001 certificates
27/05/2020 Reference to ISO 14001 removed - Whilst the same principle applies, the wording relating to product specification does not - See KBCN1401.
12/08/2021 Clarification regarding the validity of EPDs during QA submission and removal of reference to Green Guide ratings

Mat 01/02 Results Submission Tool – concept and technical design submission - KBCN1209

As stated on the Mat 01/02 Results Submission tool, uploading the Mat 01/02 Results Submission Tool to BREEAM Projects is the required method for submitting the tool at Concept and Technical Design stages; it is not required to be submitted to BRE via email. The upload will be date-stamped for the purposes of QA checks.

Product classification code for ‘Other’ materials/products - KBCN1229

In the ‘MAT02_EPDSchedule’ sheet of the Mat01/02 Results Submission Tool, the product classification ‘P8’ should be entered for products classified as ‘other’ (according to the mat 02 materials classification table in the technical manual).
