B-05 Maintenance with complete LCA

*Aspect*		B-05 Maintenance with complete LCA
*Description*		Maintenance is defined as the combination of all planned actions during the service life to maintain the product installed in a building in a state in which it can deliver its required functional and technical performance.

*Provisions*	The maintenance procedure refers only to planned action in response to anticipated losses of performance of building components and building parts. Building modifications in response to unexpected events (e.g. flood, inappropriate use, or vandalism) should be considered as reparation (B3).The overall maintenance scenario should be developed in accordance with: individual EPD (cradle to gate with corresponding option, or cradle to grave); client requirements and current practices; product and component manufacturers’ information; existing applicable standards, such as ISO 15686-1, -2, -7 and -8 [ISO 15686]. The maintenance scenario should include (EN 15804): the production and transportation of any component and ancillary products used for maintenance, including cleaning; the transportation of any wastage from maintenance processes or from maintenance-related transportation; the end-of-life processes of any wastage from transportation and the maintenance process, including any part of the component and ancillary materials removed; water and energy usage related to cleaning. Water and energy usage related to maintenance operations other than cleaning should always be included.

*Guidance*	It is expected that not all necessary information required to develop a maintenance scenario will be included in the EPDs. Nevertheless, the maintenance scenario should encompass the planned actions for listed components (see above), based on the available information. Knowledge gaps should be filled by referring to state-of-the-art practice.In addition, LCA of existing buildings should take into account real and established practices (real-life data) specific to a particular building, but scenarios based on current practice may also be developed.When developing a maintenance scenario at the building scale, the it should be consistent with the reference service life of each component or building part.Maintenance examples (from EN 15804): Painting work on window frames, doors, etc. as well as the annual inspection and maintenance of the (oil or gas) boiler […].
