The objective of the criterion is to promote the efficient use of natural resources and ensure that these are used sparingly. It encourages the recycling of materials to reduce the use of primary resources in the construction process.
The recognition of the minimum requirements for criterion TEC 1.6 is still not currently explicitly required.
The fulfilment of systemic requirements is a prerequisite for a recognition of the standard.
Standards that fulfil the minimum requirements and the systemic requirements in accordance with the requirements of criterion TEC 1.6 for selection of construction materials that are easy to recycle and building construction that enables easy recovery can be recognised by the DGNB.
The intended objective is for construction materials for components to be selected with recycling in mind. Solutions that use the current recycling paths of construction materials as a benchmark can be used to select construction materials that are easy to recycle. These recycling paths are assigned to quality levels within the criterion.
If a label fulfils the requirements of quality level 2, it can be recognised. To this end, the standard-awarding organisation must prove that the use of components that are detrimental to the environment has been precluded in its awarding criteria and that the construction materials can be 100% recycled as part of the requirements for satisfying the criteria. The recycling capability must not be constrained by compounds, coatings, adhesions or admixtures.
If the building structure is intended to be easy to recover, this can be described via the ease of disassembly and ease of separation of the components into material groups that represent specific and separate material types as far as possible. In order for the standard to be recognised, it must be documented that the certified standard components can be removed from the building using non-destructive methods and their layers can be separated into specific and distinct types. The relevant component groups that are to be taken into account for this indicator can be found in the criterion.
If a label fulfils the requirements of quality level 2, it can be recognised. To this end, the standard-awarding organisation needs to prove that their label is only awarded to components in the case that it is possible to remove the components using non-destructive methods and the component layers can be separated into specific and distinct types where applicable (separation of the layers may not be required because the individual layers/elements belong to the same (raw) material group).
For the purposes of this indicator, destruction-free removal of components means that it is possible to make the component available for loss-free reuse or further use. For this purpose, it must be possible to release the connections between the component and the building or adjacent components without destroying remaining components or component layers. For the purposes of this indicator, ease of separation of component layers into specific and separate types means that recovery of the materials is possible without limitation.Download DGNB criteria TEC1.6
