64 Page 64 Procurement - Design D-PR 4 Evauation of Loca Suppy Chain for Loca Procurement To mitigate transportation energy use and costs, and negate unnecessary use of transport. Materias originating from within 50 mies of the site shoud be seected and incorporated into the design wherever possibe. A review shoud be undertaken to identify opportunities for use of oca suppiers providing products that have originated within 50 mies of the site. This shoud cover the foowing buiding eements: 1 Structure Masonry Fooring Windows Cadding At east 30% of materias by mass shoud have the potentia to be suppied from oca sources. As we as newy manufactured buiding products, this may incude re-used or recyced materias or buiding eements. A oca timber shoud meet the requirements of credit D-PR 10. Where buidings are required in remote areas, and the review of oca suppiers shows that it is not

65 Page 65 possibe to purchase at east 30% of materias by mass within 50 mies, then this credit may be awarded by defaut. This credit shoud aso take into account off-site or moduar buiding manufacturer which shoud aso be incuded within the 50 mie radius. In exceptiona circumstances, where products which have a demonstrabe through-ife benefit for sustainabiity, these may be procured outside the quoted radii and the credits awarded by defaut. Written confirmation of the origins of products sha be obtained from the suppiers (e.g. websites, correspondence etc showing addresses of sources). In cases where products are procured outside the quoted radii there sha be written evidence demonstrating their superior sustainabiity performance.

Two credits are awarded if three of the eements are A or 'A+' rated. Three credits are awarded if four of the eements are A or A+ rated. Four credits are awarded if five or more of the eements are A or A+ rated. Five credits are awarded if six or more of the eements are A or A+ rated. 1. Roofs - 90% A or 'A+' rated 2. Externa Was - 90% A or 'A+' rated 3. Upper foors - 90% A or 'A+' rated 4. Windows - 90% A or 'A+' rated 5. Insuation - 90% A or 'A+' rated, zero ODP, GWP<5 6. Foor finishes - 90% A or 'A+' rated 7. Interna was - 90% A or 'A+' rated 8. Hard andscaping - 90% A or 'A+' rated Where materias have been reused from an existing buiding, or where major buiding eements have been retained (e.g. the refurbished buiding uses the

67 Page 67 existing externa was), these materias automaticay achieve an A rating. Where a construction eement contains more than one specification, it is permissibe to cacuate the average rating by taking account of the reative area of each individua specification. Where speciaist buidings have an outer buiding enveope, these criteria can be appied to the outer buiding ony. The design team shoud provide specifications or drawings which detai a types of materias to be used. The assessor shoud use discretion where construction types vary sighty from those specified in the Green Guide.

68 Page 68 Procurement - Design D-PR 6 Recyced Aggregate Materias To encourage the recycing of aggregate materias or puverised fue ash, thereby reducing costs by avoiding the need for andfi and unnecessary handing and transportation. To award the first credit >30% of aggregates by mass specified shoud come from recyced or secondary aggregate. Recyced aggregates come from reprocessing materias that have previousy been used in construction e.g. construction or demoition waste. Secondary aggregates are byproducts of other industria processes that have not previousy been used in construction e.g. puverised ash. To award the second credit >50% of aggregates by mass specified shoud come from recyced or secondary aggregate Credits can ony be awarded if the recyced or secondary aggregates come from sources within a 100 mie radius. Potentia appications for recaimed /recyced materias are: 2 Road pavement ayers - Bast furnace sag (air cooed) Bock work - Puverised fue ash, China cay waste

For each credit, the team shoud provide cacuations showing the tota amount of aggregates required and the amount of aggregates sourced from recaimed and/or recyced materias. The team shoud aso provide evidence of sources of recyced or secondary aggregates (e.g. etters from suppiers stating that the required voume of recaimed and/or recyced aggregates can be provided, and the origin of these aggregates). If contractua specification precudes the use of recyced or secondary aggregates an extract from the contract must be provided.

70 Page 70 Procurement - Design D-PR 7 Recyced Content of Buiding Materias To encourage the reuse and recycing of buiding materias. Encouraging the reuse and recycing of buiding materias reduces consumption of primary resources and minimises the quantity of UK waste being sent for disposa in andfi. Reuse / recycing of materias can aso reduce costs by avoiding andfi disposa charges and minimising transportation. Options incude: reuse of recaimed products; oca recycing of construction and demoition waste; and the seection of manufactured products containing a higher fraction of recovered materias. This objective inks to good practice in site waste management. Use the onine too deveoped by WRAP (the Waste & Resources Action Programme) to determine the vaue of recyced content used and the top ten opportunities to increase this outcome. The minimum outcome is 10% recyced content as a proportion of the tota vaue of materias used on the project. The Quick Wins are the argest contributors to the potentia increase in recyced content for the project, going from baseine/standard practice to cost-neutra good practice. They invove simpe substitution of one product/materia by an equivaent mainstream aternative (e.g. a competing brand with higher recyced content). 1

71 Page 71 The Credit is awarded for impementing five of the top ten Quick Win opportunities PROVIDING the projected recyced content of the project is at east 10%. Note that reuse of a product or materia (such as demoition waste used as fi) is attributed 100% recyced content by vaue, and shoud be preferentiay investigated as a potentia Quick Win. The team shoud provide the standard report from the WRAP too quantifying the projected overa eve of recyced content by vaue and identifying the top ten Quick Win opportunities for the project. Detais of the Quick Wins seected for impementation shoud be specified within this report. Evidence of the actua use of higher recyced content products for the seected Quick Wins may be sought during the construction phase (e.g. through review of product data sheets, deivery notes or invoices).

72 Page 72 Procurement - Design D-PR 9 PVC Minimisation To avoid the use of PVC materias. PVC is an inappropriate materia to use in areas of high UV exposure due to degradation of the materia. A review of materia specifications for the foowing products shoud be undertaken to identify aternatives to PVC: 1 Window frames Foor, Wa and surface finishes Furthermore, to achieve the credit, PVC use in nonexposed areas needs to be considered and aternatives specified where suitabe. The design team shoud provide specifications and/or drawings which demonstrate that aternative materias to PVC have been seected and specified.

73 Page 73 Procurement - Design D-PR 10 * Timber To ensure that timber products manufactured from sustainabe sources are incorporated into the design. The credit is achieved when timber procurement is in ine with the UK Government Timber Procurement Poicy. The poicy states that ony timber and wood-derived products originating from an independenty verifiabe Lega and Sustainabe source shoud be specified. This incudes a virgin timber and wood-derived products, incuding temporary site works and materia suppied by suppiers. Recyced timber can be used as an aternative to timber and wood-derived products from a Lega and Sustainabe source. To gain the credit, the assessor shoud be satisfied that the design specification for sustainabe timber products is in accordance with these guideines. This is a mandatory credit. To confirm this, the assessor sha be provided with (1) the design specification, and (2) any other evidence which demonstrates that the UK Government Timber Procurement Poicy has been specified in design work. 1
