B-03 Maintenance with screening LCA

Aspect B-03 Maintenance with screening LCA
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. Maintenance is optional in the context of a screening LCA.

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), and may be ignored in the context of a screening LCA.The maintenance scenario is optional for a screening LCA, and may be neglected in many cases. The boundaries of the maintenance scenario may be defined according to the goal and scope of the study (see ‘Maintenance with complete LCA’ and ‘Maintenance with simplified LCA’ for guidance).
Rules from:
EN 15978: General Boundary for maintenance (Module B2)

8.3 Time related characteristics
8.6.3 Scenarios for maintenance, repair, replacement

EN 15804:

6.3.3. Reference service life  – B2 Maintenance B1–B5 use stage related to the building fabric
Annex A

If a maintenance scenario is to be developed, it is recommended that the following building parts be addressed, in order of priority:

  • roofing and roof framework;
  • façades, exterior joinery work and windows;
  • partitioning, lining, suspended ceilings;
  • Floor finishes and covering,  walls and ceiling coverings;
  • HVAC (heating – ventilation – cooling – DHW).
