EN 15804+A1
The EN 15804+A1 method is used as the basis for various certification and assessment systems, e.g:
- DGNB (version 2018): Certification system of the German Sustainable Building Council (DGNB e.V.) for sustainable buildings (old version),
- BNB: Assessment system for sustainable building of the Federal Ministry of Housing, Urban Development and Building (BMWSB),
- QNG: Quality seal for sustainable buildings
Life cycle phases
The following life cycle phases and modules are used: Production A1-A3, exchange/replacement B4, energy B6, disposal (C3, C4), recycling (material D1, energy D2). All SURAP LCA methods also allow the assessment of transportation from the building material manufacturer to the construction site (A4).
