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-26 Assessment of operational water use in simplified LCA
Aspect B-26 Assessment of operational water use in simplified 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…

B-30 Transport of the users of the building
Aspect B-30 Transport of the users of the building Description For building LCA, the environmental impacts of transportation of people during the use stage may influence the decision between alternative construction sites (e.g. is the building located near public transport services?), or between alternative projects for the same site. Generally speaking, if the transport of…

B-31 (Buildings) / B-11 (Products) Distinction between Modules B2, B3, B4 and B5
Aspect B-31 (Buildings) / B-11 (Products) Distinction between Modules B2, B3, B4 and B5 Description Modules B2 to B5 cover the impacts related to the service life of building and building parts, whether it is a light modification, such as a small maintenance operation or an important retrofit (rehabilitation).It is sometimes difficult to determine which…
