scope:

In a conscious move, not every detail is prescribed in this guideline, so that possibilities are left open for methodical further development and application.

In the course of determining the KEA of products and services one obtains a basis for the calculation of respectively indications on

• the related materials expenditures,
• the selection of materials and process technology with respect to energy criteria,
• the relevance of the treatment of used goods through energetic exploitation and disposal as well as through the recycling of parts, components or materials under energy aspects,
• the influence of the service life of energy consuming or energy converting economic goods (products and services) under energy aspects, and
• the emissions related to energy conversions during production, use and disposal.

The KEA allows the evaluation and comparison of products and services with respect to energy criteria. The data on the KEA which can be quantified by means of this guideline form an important base in order to point out the priorities of energy saving potentials in their complex relationship between design, production, use and disposal.

As far as the database permits, the KEA can be divided into fossil, nuclear and regenerative shares. This can be advantageous while determining energy- induced emission balance-sheets.
