11、nce from The British Standards Institution, and came into effect on 31 March 2015. It was prepared by Technical Committee B/555, Construction design, modelling and data exchange. A list of organizations represented on this committee can be obtained on request to its secretary.Relationship with other

12、 publicationsBS 8541 comprises six parts as follows: Part 1, Identification and classification Part 2, Recommended 2D symbols of building elements for use in building information modelling Part 3, Shape and measurement Part 4, Attributes for specification and assessment Part 5, Assemblies Part 6 (th

13、is part), Product and facility declarationsBS 8541-1, BS 8541-3 and BS 8541-4 document best practice for the development and application of construction library objects to support Building Information Modelling (BIM) based design, standardization, specification and construction processes. See BS 854

14、1-1 and Figure 1.BS 8541-2 documents best practice for the use of 2D symbols for construction objects. BS 8541-5 and BS 8541-6 document best practice for the transmission of assemblies of construction objects and for the transmission of formal performance declarations of products and facilities.The

15、IFC standard (BS ISO 16739) includes recommendations for the association of base quantities and geometry for objects. The use of the IFC standard can be supplemented by using UK specific recommendations, such as are published by buildingSMART UK on behalf of RIBAE NBS under its UK national BIM Libra

16、ry initiative. For further information on work within ISO, see BS 8541-1.

17、f BS 8541 takes the form of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading.Any user claiming compliance with this part of BS 8541 is expected to be able to justify any cour

18、se of action that deviates from its recommendations.Presentational conventionsThe provisions in this standard are presented in roman (i.e. upright) type. Its recommendations are expressed in sentences in which the principal auxiliary verb is “should”.Commentary, explanation and general informative m

19、aterial is presented in smaller italic type, and does not constitute a normative element.1)http:/ viewed: 24-3-2015BS 8541-6:2015iv The British Standards Institution 2015BRITISH STANDARDThe word “should” is used to express recommendations of this standard. The word “may” is used in the text to expre

20、ss permissibility, e.g. as an alternative to the primary recommendation of the clause. The word “can” is used to express possibility, e.g. a consequence of an action or an event.Notes and commentaries are provided throughout the text of this standard. Notes give references and additional information

21、 that are important but do not form part of the recommendations. Commentaries give background information.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a B

22、ritish Standard cannot confer immunity from legal obligations. The British Standards Institution 2015 1BS 8541-6:2015BRITISH STANDARD1 ScopeThis part of BS 8541 gives recommendations on the transmission of product declarations relating to construction library objects and facility declarations (inclu

23、ding 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 env

24、ironmental 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

25、 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. T

26、he 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 Con

27、struction 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

28、 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 IS

29、O 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 recom

30、mendations. 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 cover

39、N ISO 9000:20054 Declaration processes4.1 Preparation and publication The product manufacturer or other library supplier should provide product data, including any current product declarations, in a form that can be used by BIM processes to support the following purposes:a) reviewing and confirming

40、declarations by providing the references to definitive resources;b) specifying and selecting conformant products or facilities by structuring the performance data in a checkable format; The British Standards Institution 2015 3BS 8541-6:2015BRITISH STANDARDc) comparing alternative compliant product a

41、nd facilities by structuring the performance data in a sortable format; andd) analysing and predicting performance by providing clear explanation of the scenarios assumed alongside the values.4.2 UseUse should be determined by the declaration scheme objectives and limitations. Confirmation of the de

42、claration information should be undertaken when used for reporting, for validation and for comparison.Declarations of minimum or maximum performance should not be compared with typical performance and should only be used with caution in simulations and analysis.Schemes may use different bases for th

43、e assessment, and so values provided under different schemes should not be compared.EXAMPLE: What is measured by BS EN 15804 as global warming potential (GWP) is not the same as what is measured as climate change by BRE Environmental Profiles 2008 1nor the same as what ICE measures as embodied carbo

44、n (which is reported separately for ECO2and ECO2Eq).5 Principles for the exchange of declarations5.1 Construction objectsAny declaration attached to a construction library object should be based on the associated quantity measures of the product or facility (see Figure 2).NOTE 1 See BS 8541 Parts 1

45、to 4 for more information on the exchange of product data.Facility information should follow similar standards particularly in relation to naming, classification and measurement Figure 2 Construction objectThe quantity should be provided as mass and/or volume, or on a unit product, or in some cases

46、areas or thicknesses (see Table 1 and Table 2).NOTE 2 For more information see BS 8541-3.Table 1 Quantity set definitionQuantity set name BaseQuantitiesApplicable entities IfcMaterial, IfcTypeProduct, IfcBuilding, IfcProxyDescription Base QuantitiesBS 8541-6:20154 The British Standards Institution 2

49、aration should be transmitted as a grouped set of properties so that the performance values provided have sufficient context to enable appropriate use.NOTE 1 The use of property sets separates the declaration from other values and allows multiple declarations to be transmitted within one construction library object.The property set should be named so as to identify the declaration scheme, the product or facility type and the applic
