B-07 Repair with simplified LCA

Aspect B-07 Repair with simplified LCA
Description The repair module covers all corrective, responsive or reactive treatment of a building product or construction works to return it to a condition in which it can deliver its required functional and technical performance. It covers only the partial replacement of components and building parts (in case of failure), and should be distinguished from the replacement module, which is related to the complete replacement of component and building parts.

Provisions Repair is optional in the context of a simplified LCA. For provision and guidance, please refer to the aspect ‘Repair with complete LCA’ of the present document.The reparation procedure refers only to corrective, responsive or reactive actions in response to loss of performances of a building component or building part.Repair is distinguishable from maintenance and replacement by the following aspects [EN 15804]:

  • Maintenance is a planned (proactive) action that maintains component performance, whereas repair is a corrective (reactive) action in response to damage.
  • Replacement covers the complete replacement of a component, whereas repair covers only replacement of sub-components.

According to EN 15978, the boundary for repair should include:

  • production of the repaired part of the component and ancillary products;
  • transportation of the repaired part of the component and ancillary products, including production impacts;
  • aspects of any losses of materials during transportation;
  • the process of repairing the part of component and ancillary products;
  • waste management of the removed part of the component and of ancillary products;
  • the end-of-life stage of the removed part of the component and of ancillary products.

Water and energy usage related to the repair process should always be included.

However, in the context of a simplified LCA, only the production of the replaced component/repaired part need be included.
