Method for monitoring
To monitor embodied energy, two elements are necessary:
The energy content of specific building materials, including transportation
The quantity of these materials used in different building segments
Some methods also include the energy needed for the disposal and reuse of materials.
Although, this seems rather straightforward, both elements are difficult to get right. Organisations, some within but mostly outside the EU, have worked on analyses for embodied energy. Their knowledge, mostly applied to single buildings or projects, can be used for nationwide monitoring. Below we describe the approaches for the two elements.
