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…

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…

in Existing buildings, New buildings

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…
