1   Scope

This part of BS 8541 gives recommendations on the transmission of product declarations relating to construction library objects and facility declarations (including buildings, infrastructure and built assets). It applies primarily to manufacturers’ specific products, but the principles and some examples are also applicable to facility declarations.

NOTE 1 Independent declarations are an increasingly important aspect of product and facility data, covering environmental and other performance.

This part of BS 8541 gives recommendations on conveying declarations as part of a standard product data set (supplementary to printed labels, annexes and document lodgement) and integrates product and facility declarations into information-driven design, construction and operational processes.
This part of BS 8541 is applicable to any independent declaration scheme and establishes principles for the identification of declarations and their origin. It defines the level of information appropriate for specific uses including confirmation, reporting, and analysis. The intent is to allow any declaration to be communicated with indications as to the degree of attestation offered. The specific values declared are given in the context of a specific declaration scheme and supported with details of the relevant life cycle stage and details of its scenario.

NOTE 2 Construction products regulations and CEN standards for buildings and products provide the primary examples. This part of BS 8541 supports the communication of the voluntary environmental product declarations (EPDs) required by BS EN 15804 and BS EN 15978, as well as the CE marking details, in a format which can be incorporated in Building Information Modelling (BIM) processes. It also covers the communication of other product declarations such as wastage rates developed with the UK Government WRAP programme and UK government display energy certificate (DEC) declaration scheme.

NOTE 3 COBie, BS ISO 16739 IFC and IFCXML are used as example formats with reference to BS ISO 10303‑21 and ISO/TS 10303-28. These formats can be mapped to standard printed forms if required.

NOTE 4 In situations where the adoption of data-driven design is partial or incomplete, this part of BS 8541 gives further recommendations. If a particular project is formally committed to integrated working then this standard may be adopted as a requirement.

NOTE 5 Self-declared environmental claims (such as described as Type II environmental labels in BS EN ISO 14021) have the lowest degree of attestation but are also covered by this standard.
