“eu.bac System” certification was created in 2013 to ensure that building technology and building automation are thoroughly taken into account in systematic evaluations. The standardized evaluation method is based on scientifically tested data and the relevant European standard, DIN EN 15232. The audits are conducted by recognized experts trained and approved by the European Building Automation and Controls Association, an organization of European manufacturers of building automation systems. Building operators in turn also benefit from this consultation. The efficiency and sustainability of buildings can be ensured through systematic evaluation based on the eu.bac System – saving energy and reducing operating costs over the entire lifetime of a building.
