B-19 Operational energy demand for new buildings – Boundaries and scenarios for complete LCA
Aspect B-19 Operational energy demand for new buildings – Boundaries and scenarios for complete LCA Description Several parameters can influence the results of the operational energy demand for the use stage of buildings, such as the selection of uses (i.e. building-related or non-building-related uses). European standards (EN 15804/EN 15978) recommend taking account of priority building-related…

B-20 Operational energy demand for existing buildings – Boundaries and scenarios
Aspect B-20 Operational energy demand for existing buildings – Boundaries and scenarios 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 15978) recommend that…

B-21 Operational energy demand for new buildings – Consideration of user behaviour
Aspect B-21 Operational energy demand for new buildings – Consideration of user behaviour Description Several parameters influence the results of the energy calculation demand at the operational stage of buildings. Among others, user behaviour may have a major significance on the energy needs. The following section aims at providing guidance for screening, simplified and complete…

B-23 Operational energy calculation – Allocation of energy production for on-site systems connected to grid”
Aspect B-23 Operational energy calculation – Allocation of energy production for on-site systems connected to grid” Description Current new buildings may not only be energy-efficient, but can also produce energy on site in multiple ways.The energy produced on site may not only be consumed inside the building, but can also be exported. When energy is…

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…

B-27 Assessment of operational water use in complete LCA
Aspect B-27 Assessment of operational water use in complete LCA Description The operational water use assessment includes water used during the operation of the building, together with the associated environmental impacts and aspects, including the production of drinking water and wastewater treatment. A link between domestic hot water and energy use should also be considered.…

B-28 (Buildings) / B-10 (Products) Accounting of different types of waste water treatment
Aspect B-28 (Buildings) / B-10 (Products) Accounting of different types of waste water treatment Description The environmental impacts are different for the various methods of waste water treatment. The system boundaries for waste water treatment considered within the studies (e.g. public sewage system, on-site treated water) and the classification of waste water treatment need to…
