B-10 Assessment of different repair and maintenance alternatives
Aspect B-10 Assessment of different repair and maintenance alternatives Description The performance of a product often depends on maintenance. However, several maintenance schemes may be developed for the same product, depending on the owner’s requirements and the building specifics. In the case of the repair module, several repair alternatives may also be considered, notably for…

B-11 (Buildings) / B-06 (Products) Definition of the service life of a building product
Aspect B-11 (Buildings) / B-06 (Products) Definition of the service life of a building product Description The lifespan, or service life, of building components and elements is usually defined as the period of time during which their performance meets or exceeds initial requirements. More detailed definitions can be found in reference work (e.g. the ISO…

B-13 Replacement with screening LCA
Aspect B-13 Replacement with screening LCA Description The replacement module covers the complete replacement of components and building parts if their reference service life is lower than the reference study period. Replacement is optional in the context of a screening LCA. related study objective ☒ stand-alone LCA ☒ comparative assertion related study phase ☒ ☐…

B-17 Operational energy demand for new buildings – Boundaries and scenarios for screening LCA
Aspect B-17 Operational energy demand for new buildings – Boundaries and scenarios for screening LCA Description Several parameters can influence the results of the energy demand at the operational stage of buildings. Among others, the selection of uses (i.e. building-related or non-building-related uses) has a major significance on the energy demand. European standards (EN 15804/EN…

B-24 Dynamic LCA data for assessing the impact of electricity consumption
Aspect B-24 Dynamic LCA data for assessing the impact of electricity consumption Description Energy sources for electricity production may vary significantly according to the season (winter or summer months), the day (weekdays, weekends) and the time within a day. Environmental impacts are strongly influenced by the decision to use annual energy data (i.e. average LCA…
