Zusammenfassung
The basic concept of a Net Zero Energy Building (Net ZEB) is that on-site renewable energy generation
covers the annual energy load.
The main objective of this study is to analyse the increase of embodied energy compared to the decrease
of the energy use related to building operation; partly by a literature review, partly by detailed analysis of
eleven case studies; taking the step from a low energy building to a Net ZEB. The literature review shows
that the metric of evaluation, assumed life-span, boundary conditions, age of database and the origin of
database differ in different studies and influence the result of embodied energy. The relationship between
embodied energy and life cycle energy use is almost linear for all cases studied herein. During the last
two decades, embodied energy in new buildings has decreased slightly. However, the relative share of
embodied energy related to life cycle energy use has increased. The detailed life cycle energy analysis
show that taking the step from a low energy building to a Net ZEB results in a small increase of the
embodied energy. However, the energy savings achieved in the annual operating energy balance clearly
exceed the increase in embodied energy.
