|Aspect||B-08 Repair with complete 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. This aspect of the EeBGuide also addresses the distinction between repair, maintenance and replacement.|

|Provisions||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]:
It should be noted that:
It is thus to be expected that little information related to the repair module will be included in cradle-to-grave EPDs (or cradle-to-gate with corresponding options). Instead, most information would probably be divided between the maintenance module (necessary operations to maintain product performance, including sub-component replacement, in a given set of in-use conditions) and the replacement module (replacement at the end of life of the component).
Consequently, the repair module is considered optional in the context of the present guide.
According to EN 15978, the boundary for repair should include:
Water and energy usage related to the repair process should always be included.

|Guidance||Repair is optional in the context of complete LCA in the case of insufficient data.The overall repair scenario should be consistent with respect to the building structure (e.g. replacement of coating is mandatory when replacing the support). In the context of a complete building LCA of an existing building, it is recommended that the repair module be based on the history of the building.The progressive loss of performance of some components has an impact on the overall behaviour of the building (e.g. loss of performance of insulation may lead to an increase of energy demand due to heating). If sufficient data are available, these aspects should be addressed by using a sensitivity analysis.|
