Terms |
Description |
---|---|---|
CN1 |
Government’s Policy for UK Timber Procurement. See criterion 3 |
The UK Government’s timber procurement policy requires that all timber and wood-derived products must be from only:
Some of the responsible sourcing schemes listed in the Additional Information section of this BREEAM issue will meet this definition. Further information on the UK Timber Procurement Policy and compliant responsible sourcing certification schemes is available from the CPET (Central Point of expertise for timber procurement) website: www.cpet.org.uk |
CN2 |
Checking responsible sourcing claims See criterion 1c | Confirmation of claims should be sought from the relevant scheme provider. Many of the organisations who administer certification schemes will, via their website, list companies and products that have been certified against their standards, including the scope of any such certification. Some schemes, including BES 6001 via www.greenbooklive.com, will provide downloadable copies of the relevant certificate, which can in turn be used as evidence of compliance with this BREEAM issue. |
CN3 |
Building element not present. See criterion 2c |
Where an element is not present, e.g. the building has no upper floors because it is a single storey building, it will not require assessment. In such instances, the element can be defined ‘not applicable’ in the BREEAM Mat 03 calculator and only those elements present contribute towards achieving responsible sourcing points and BREEAM credits. |
CN4 |
Existing elements re-used in the new construction. See criteria 1 & 2 | If the building is re-using any existing in-situ elements, those elements do not need to be accounted for in the assessment of this issue. This may be the case where the new development is re-using an existing façade e.g. it is a new-build extension or is a part new-build part refurbishment project. The same applies to site derived masonry where it is used as a base for hard landscaping. The aim of this issue is to focus on the responsible sourcing of new specified materials only. |
CN5 |
Hard landscaping element. See criteria 1 & 2 | Hard landscaping is listed as one of the main building elements to be assessed where present. However, where the footprint area of hard landscaping element is smaller in proportion to that of the gross floor area of the building, it must be excluded from the list of applicable elements and materials assessed. |
CN6 |
Fittings element See criteria 1 & 2 |
The definition of this element includes a number of separate fittings/finishing elements (refer to Table 23 below). As with the other elements covered by this issue, only the materials that make-up a significant majority (at least 80%) of the finishing elements need to be considered when determining the points contribution (though the option to consider them all is available). This element must be excluded for assessments of shell only projects and industrial buildings/units (as these projects use no or very few materials for fittings/finishes). |
CN7 |
Specified reused materials. See criterion 1c |
Reused materials specified for the development are considered equivalent to materials covered by certification schemes that fall within tier 3 of the Responsible Sourcing Tier Levels and Criteria, Table 24. See also note below on pre or post consumer waste. |
CN8 |
Pre or post consumer waste. See criterion 1c & 3 | Where materials being assessed (including timber) are part of a pre or post consumer waste stream, the EMS sections of the credit can be applied for; however, using an EMS scheme (ISO, EMAS etc.) for new timber does not demonstrate timber certification and therefore does not qualify for any of these BREEAM credits. |
CN9 |
Insulating materials. See criterion 1a |
The responsible souring of materials used for insulating the building fabric and services is assessed as part of BREEAM issue Mat 04 Insulation. Therefore insulating materials are not assessed as part of this issue, but they are still subject to the BREEAM responsible sourcing requirements. |
CN10 |
A Government licence. See criterion 3 |
A Government licence e.g. UK Forestry Commission felling licence certificate, does not comply as a third party timber certification scheme for this issue, but can be used as evidence of legally sourced timber. |
CN11 |
Multi-residential developments with CSH assessed dwellings. See criterion 1,2 & 3 |
For multi-residential developments that also have self-contained dwellings being assessed under the Code for Sustainable Homes (CSH), the following applies: The CSH and BREEAM have a different number of credits available for this issue. The credits achieved in the CSH cannot therefore be applied directly to a BREEAM assessment of a multi-residential building. However, the assessment criteria for this BREEAM issue is similar to the CSH, so where the building is compliant with issue Mat 2 of the CSH, the building assessment is inherently compliant with this issue (albeit the number of credits that can be awarded may differ). Where this is the case, the construction details of each element and the tiers that each material complies with should be entered into the BREEAM Mat 03 calculator to determine the number of credits achieved for this BREEAM issue. |

The following outlines the calculation procedure that determines the number of credits achieved for responsible sourcing:
Material | % of element | Tier level achieved | Points achieved (material) | % of element 'responsibly sourced' | % contribution to responsible sourcing' | Points achieved (element) |
---|---|---|---|---|---|---|
Bricks | 54% | 4 | 2.50 | 54% | 66% | 1.65 |
Aircrete concrete block | 22% | 3 | 3.00 | 22% | 27% | 0.80 |
External cement mortar and screed | 13% | 8 | 0.00 | 0% | 0% | 0.00 |
Plaster | 6% | 5 | 2.00 | 6% | 7% | 0.15 |
Internal cement mortar and screed | 5% | 8 | 0.00 | 0% | 0% | 0.00 |
Element total | 100% | - | - | 82% | 100% | 2.60 |
Note:
Materials that contribute the largest percentage to an element should be prioritised and, once the 80% threshold has been reached, it is not necessary to consider the remaining 20% of materials (particularly if they make-up only a small fraction of the element). However, the assessor and design team should bear in mind that it may be beneficial to include small percentages of materials that are in tiers higher than those materials assessed as part of meeting the 80% threshold. This could make the difference where a project is close to or on the threshold between credit levels.

There are two ways of determining this for materials and elements where responsible sourcing is assured:
Or, where the specification does not match a Green Guide rated specification and/or a material breakdown cannot be sourced via the online Responsible Sourcing calculator;
BRE Global can, via its online Responsible Sourcing Calculator, provide licensed BREEAM assessors with a percentage breakdown of materials for any elemental specification with a Green Guide rating. Assessors can use the online tool to determine the percentage breakdown in two ways; either by entering an individual Green Guide element number for the required specification (if known) or through a search function, by element and specification type. The online Responsible Sourcing Calculator can be accessed by licensed BREEAM assessors via the BREEAM Assessor Extranet.
Note:
In their certification report the BREEAM assessor must reference the Green Guide element number for any data sourced from the online Responsible Sourcing Calculator.
When sourcing information from component manufacturers or project estimators, information on areas, lengths and volumes of timber is likely to be available and provided. In order to calculate the volume of wood in timber frame windows, the total length of frame must be obtained. This can then be converted to a volume by multiplying the length of frame on fixed windows by 0.00653 and the length of frame on opening windows by 0.01089.
In order to calculate the volume of timber in composite timber doors such as a flush door, calculate the total area of all doors summed over the whole building and multiply this by 0.02187 (this factor gives the total volume of timber in the doors and frames).
This is a BRE Global standard that provides a framework for the assessment and certification of the responsible sourcing of construction products. The Standard has been structured so that compliance can be demonstrated through a combination of meeting the requirements of other recognised certification schemes, establishing written policies, setting objectives and targets and engaging with relevant stakeholders.
To comply with the standard a product must meet a number of mandatory criteria. Where a product demonstrates compliance beyond the mandatory levels, higher levels of performance can be achieved. The standard's performance ratings range from Pass to Good, Very Good and Excellent.
The development of this standard and subsequent certification schemes will, it is envisaged, provide construction products, not wholly covered under current recognised standards, a means for demonstrating their responsibly sourced credentials. In turn this will allow clients, developers and design teams to specify responsibly sourced construction products with greater assurance and provide a means of demonstrating compliance with the assessment criteria for this BREEAM issue.

BS 8902:2009 is not included in the tier table as it is not a product standard; rather it is a standard against which other sector standards for responsible sourcing can be assessed. BRE Global recognises that sector schemes compliant with BS 8902:2009 may be developed in the future and should be eligible for inclusion within this Table. Inclusion of schemes deemed as compliant with BS 8902:2009 will be considered by BRE Global on a case-by-case basis to determine their position within the table’s Tier hierarchy. A sector scheme deemed compliant with BS 8902:2009 by an appropriate third-party accreditation body will secure more tier points than an equivalent but unaccredited scheme.
