Self-protection against floods is becoming increasingly important. This is particularly true for the protection of residential buildings. The information tool FLOOD.Bi can be used to determine and minimise the risk of flood damage to buildings. The Leibniz Institute of Ecological Urban and Regional Development (IOER) developed the tool together with the Saxon State Office for the Environment, Agriculture and Geology (LfULG) in the EU project STRIMA II. From 2 to 5 March, a team from both institutions presented the online tool at the "HAUS", a construction fair in Dresden.
