10、about this documentThe initial drafting of this British Standard was produced in association with BISas part of their on-going programme of support for standardization.This document gives recommendations for designing for material efficiency thatare accepted as good practice by industry leaders and

11、practitioners, and bringstogether the results of practical experience and acquired knowledge for ease ofaccess and use of the information.This code of practice sets out the process for the integration of designing formaterial efficiency into the concept design and developed design stages of theRIBA

12、plan of work N1. It is the second part in a projected suite of BritishStandards that address specific and interrelated issues and processes of materialefficiency in building projects in line with the RIBA plan of work N1.BS 8895, Designing for materials efficiency in building projects, comprises the

18、ing project. Material efficiency encompasses the efficient use ofmaterials throughout the lifecycle of a building, waste prevention andreduction, minimizing damage to the environment and minimizing depletion ofnatural resources. The case for material efficiency is made in the Part 1 of thismulti-par

19、t standard, BS 8895-1:2013, which covers Stage 0 Strategic Definitionand Stage 1 Preparation and Brief of the RIBA plan of work N1. This includesclear drivers such as cost savings and reduced environmental impact throughreduced resource use, corporate social responsibility commitments and meetingreq

20、uirements for material efficiency performance. BS 8895-1:2013,Figure 3 illustrates the need to design for material efficiency at the earliestpossible point within the design process where the opportunities are thegreatest and the cost of making the decisions the least.Material efficiency in a buildi

21、ng project involves the implementation of ahierarchy, (see BS 8895-1:2013, Figure 1) to optimize material usage and avoidthe production of waste. It also encompasses design solutions to reduce materialusage wherever possible, reuse materials and increase the use of materials whichare reclaimed that

22、can also be reused at the end of life, and specify materialswith a high level of recycled content and that can be recycled.Opportunities and solutions for material efficiency arise during the planning,design, procurement, construction, in use (including refurbishment) and end oflife stages of a proj

23、ect. However, the most effective way to implement materialefficiency is to comprehensively consider the use of materials during theplanning and design stages. This is when maximum impact can be made. ThisBritish Standard covers Stage 2 Concept Design and Stage 3 Developed Designof the RIBA plan of w

24、ork N1 where there is much potential to implementmaterial efficiency by taking forward the initial project brief and consideringopportunities that arise from the work undertaken to develop the outlinedesigns and specifications.Opportunities also exist when the design is already formulated and constr

25、uctionis under way, particularly in contractual procedures where the contractor has theopportunity to put forward alternative design, procurement and constructionmethods that can accrue significant reduction in waste and improvement inmaterial efficiency during the construction period.1 ScopeThis pa

26、rt of BS 8895 gives recommendations for the processes, informationexchanges and responsibilities for design teams to incorporate into projects atthe concept design and developed design stages of a building project. Itprovides recommendations on how to implement material efficiency afterreceiving the

27、 initial project brief at the end of stage 1 of the RIBA plan of workN1 (preparation and brief).NOTE 1 This British Standard follows the RIBA plan of work N1 stages andrequirements, focusing on Stage 2 Concept Design and Stage 3 Developed Design.Stage 0 Strategic Definition and Stage 1 Preparation a

28、nd Brief are covered inBS 8895-1.BRITISH STANDARD BS 8895-2:2015 The British Standards Institution 2015 1BS 8895-2 is intended to be used by the design team when preparing conceptand developed designs to include proposals for material efficiency. These theninform the final project brief and other st

29、rategies such as the sustainabilitystrategy and project execution plan. During the developed design stage thematerial efficient proposals are embedded within the design and other relatedinformation. Some of the design activities might occur in either the conceptand/or developed design stages depende

30、nt upon the complexity andprocurement route of the project. BS 8895-2 takes account of this, providing aflexible approach in applying material efficiency.NOTE 2 Material efficiency includes optimizing material use, using reclaimedmaterials, increasing the proportion of materials with a higher level

31、of recycledcontent, using durable materials, designing out waste, planning and enabling fordeconstruction, waste reduction, reuse, and recycling. These are consideredthroughout the buildings lifecycle.NOTE 3 For an explanation of the case for material efficiency including thefinancial, environmental

32、 and social drivers, see BS 8895-1.NOTE 4 Annex A shows the core objectives and information exchanges in relationto material efficiency at each of the seven stages of the RIBA plan of work N1stages.2 Normative referencesThe following reference documents are indispensable for the application of thisd
