LIFE CYCLE ASSESSMENT – PRIMARY ENERGY
Page 2 of 69
OBJECTIVES AND RELEVANCE
The criterion evaluates the complete primary energy requirement of a building. Here particular value is
placed on the reduction of the overall consumption of primary energy and the maximisation of the use of
renewable energies. Here the objective is over fulfilment of the legal regulations to the benefit of global
protection of the climate and resources.
Additional Explanation
Results must be established for the following indicators and incorporated into the evaluation:
1. Non-renewable primary energy demand (PEnren),
2. Total primary energy demand (PEtot),
3. Proportion of renewable primary energy
1. Non-renewable primary energy demand (PEnren)
The requirement for non-renewable primary energy is established over the life cycle for manufacture, repair,
operation and removal/disposal of the building.
The requirement for non-renewable energy refers to area and year and it is indicated in [kWh / m2NGFa*a].
The values necessary for the calculation (as in the criterion ENV1.1 "Life Cycle Impact Assessment") can be
