Provisions No specific definition is given. The LCA calculation rules must be appropriate for all building products.
Rules from:

EN 15804

The standard does not refer to energy-efficient products in particular, but the standard can be used to assess any product, component or element used in the building, including the assessment of building-integrated technical systems, as defined in B6–B7 use stage information modules related to the operation of the building:

B6 Energy use to operate building-integrated technical systems

CEN/TR 15615

Explanation of the general relationship between various European standards and the Energy Performance of Buildings Directive (EPBD) — Umbrella Document.
An energy-efficient building can consist of a whole range of building products and technical equipment; many of the usual ones will not influence energy consumption in use. Conversely, an ‘energy-efficient’ product can be one that increases the energy efficiency of the whole building. However, in the EeBGuide there is no existing differentiation between these different types of product in terms of assessing their life cycle impact, and product LCA data can be provided for building services equipment such as heating, air conditioning, transportation and lighting.Energy-using products (EuP) are now covered alongside energy-related products in the EcoDesign Directive.

Energy-related products (ErP) are products such as windows and insulation, or products with thermal mass, which have an impact on the energy use of the building, but do not directly use energy themselves, and which are not part of the building-integrated technical system.  These are also covered by the EcoDesign Directive.

In all cases, the particular use of the products in the building, and the design of the building, are key to understanding the performance of the product, and the operational performance of the building can only be assessed at the building level.
