Level(s) Reporting #

The Level(s) approach is adapted to the Level(s) European reporting framework for sustainable buildings. It uses Environmental Product Declarations (EPDs) according to EN15804+A2.

This approach can also be used for other certifications that accept the Level(s) system, e.g. within the category LEED BD+C: New Construction of the LEED certification system (Leed v4.1).

Life cycle phases #

The following life cycle modules, in accordance with EN 15978, are available in the SURAP Level(s) database: A1-A3, A4, A5, B4, B6, C1, C2, C3, C4, D1, D2.
