19、 three key resource efficiency goals of any goodpractice sustainability strategy, and involves various components intended toensure the efficient use of materials, waste prevention and reduction, andminimal damage to the environment and depletion of natural resources.Figure 1 sets out the key aspect
20、s of material efficiency and, more specifically,how this is broken down in terms of ”materials in” during the design processand ”materials out” in terms of project delivery. The focus of this code ofpractice is on the ”materials in” aspects, though the design can have asignificant influence on the a
21、bility to implement “materials out” aspects.Figure 1 Material efficiency components relating to material selection during design (materials in)and waste management on site (materials out)Material efficiency on a building project involves the implementation of thewaste hierarchy (see Figure 2) to red
22、uce the use and waste of materialswherever possible, reuse materials and increase the use of materials with ahigher level of recycled content, and recover and recycle any waste that arises,with disposal being the last resort once all other options have been exhausted.BRITISH STANDARD BS 8895-1:2013
23、The British Standards Institution 2013 1Figure 2 Material efficiency and the waste hierarchy0.2 Implementing material efficiency through designOpportunities and solutions for material efficiency arise during planning, design,procurement, construction, refurbishment and use, and at end of life. Howev
24、er,the most effective way to implement material efficiency is to comprehensivelyconsider materials and waste during the design and planning stages of a project.This is when maximum impact can be made.NOTE Figure 3 outlines the opportunity curve for integrating material efficiencyand waste reduction
25、against each stage of a project. The majority of opportunitiesto reduce waste and increase material efficiency exist up-front during the design andplanning stages, when the design can be altered to take into account solutions thatreduce waste and optimize materials. As the design develops through th
26、epreparation and design stages, decisions are taken and the design becomes morefixed, making it more difficult to implement opportunities for waste reduction.Opportunities also exist when the design is already formulated and construction isunder way, particularly under a design and build contract wh
27、ere the contractor hasthe opportunity to put forward alternative design, procurement andconstruction methods that can accrue significant reduction in waste during theconstruction period. However, with other procurement routes the emphasis is moreon waste management and recovery rather than reduction

29、gning for materialefficiency at the earliest point possible on a project, but there are furtherdrivers, including:a) cost savings from greater material efficiency and avoidance of increasedwaste disposal and landfill costs;b) reduced resource extraction, processing and consequential carbon dioxide(o
30、r equivalent) emissions from transport and manufacture of materials, aswell as reduced depletion of landfill capacity (environmental drivers);c) commitment to sustainable construction and good environmentalmanagement (corporate responsibility drivers);d) meeting requirements for improved performance
31、 and achievement oftargets, and correlation with parallel environmental rating systems,particularly in relation to the adoption of good waste minimization andmanagement practices (project-specific drivers);e) increased competitive differentiation that improves project efficiencythrough a reduction i
32、n construction costs and programme, particularlywhere waste reduction opportunities can help to meet the prospectiveclients sustainability objectives.NOTE Planning for waste reduction requires a number of disciplines tocontribute and to monitor performance throughout each stage.0.4 The objectives an
33、d intended audience of this standardBS 8895-1 is an industry code of practice for designing for material efficiency,giving recommendations for the processes and project responsibilities fordesigners to incorporate into projects. Creating a standardized and qualifiedapproach for designing for materia
34、l efficiency allows for clients and designteams to integrate the principles of designing out waste (see 4.5), andcommunicate these in a formalized and easily referenced manner.BRITISH STANDARD BS 8895-1:2013 The British Standards Institution 2013 3BS 8895-1 is specifically intended for design teams,
35、 in assisting the client tointegrate the process of designing for material efficiency during the pre-designstages, to set out the strategic direction for material efficiency in a building orrefurbishment project. It is also applicable to the broader project team memberswho can influence material sel
36、ection and, as a consequence, waste producedthroughout a project. As such, the standard emphasizes the need at RIBA Planof Work N1 Stage 0, Strategic Definition, and Stage 1, Preparation and Brief,to consider material efficiency throughout all subsequent project stages.BS 8895-1 is intended to be us
37、ed when the client, in discussion with anyconsultants, first appraises and documents their project needs, aims, resourcesand parameters to produce the initial project brief to be referenced by theclient and design team throughout project design development.It is of particular relevance for the lead
