Flood risk analysis in the context of BREEAM certification

The Building Research Establishment Environmental Assessment Method (BREEAM) is the world's leading sustainability assessment and certification system for the built environment. The quality of a building and its operation is assessed against nine environmental categories. A key element of this is the assessment criterion Rsl 01 Flood Risk (Environmental Category Resilience), which forms part of the minimum standard for the quality of a building. It includes an assessment of the flood risk for the analysed building. The combination of the number of flood sources considered and their risk classification results in a score that leads to the recognition of sustainability benefits or performance levels. As part of the project, the flood risk for a building in Hanover, Lower Saxony, was assessed and a BREEAM risk classification was carried out.
