B- 08. “Repair with complete LCA”

*Aspect*		B- 08. “Repair with complete LCA”
*Description*		Repair module covers all corrective, responsive or reactive treatment of a construction product or construction works to return it to a condition in which it can perform its required functional and technical performance. It covers only the partial replacements of components and building parts (in case of failure), and shall be distinguished from the replacement module that is related to the complete replacement of component and building parts. This aspect of EEB Guide also addresses the distinction between Repair, Maintenance and Replacements.

*Provisions*	The reparation procedure refers only to corrective, responsive or reactive actions in response to losses of performances of a building component or building part.Repair is distinguishable from Maintenance and Replacements by the following aspects [EN 15804]: Maintenance is a planed (proactive) action that maintain components performances 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. It should be noted that: EPD containing information about the reference service life of a product shall comply to the ISO 15686 series [EN 15804]; RSL shall be declared with a description of use that should (normally) encompass maintenance (proactive actions), according notably to ISO 15868-8; Manufacturer cannot be held responsible for the actual design of the building and the use and application of the product, environment, workmanship or use [EN 15804]. It is thus to be expected that few 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 performances, including sub-component replacement, in a given set of in use conditions) and 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 shall include: the production of the repaired part of component and ancillary products; the transportation of the repaired part of component and ancillary products, including production impacts and aspects of any losses of materials during transportation; the repair process of the repaired 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.

*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 complete building LCA of an existing building, it is recommended to base the repair module on the history of the building.The progressive loss of performances of some component has an impact on the overall behavior 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 aspect should be addressed by using a sensitivity analysis.
