Optimisation of building automation in existing municipal buildings

Performance monitoring of technical building equipment

Abstract

For municipalities, achieving ambitious climate targets involves, among other things, the energy-efficient refurbishment of existing buildings. This essentially consists of replacing heat generators, installing  photovoltaics, insulating the building envelope and replacing windows. Potential from optimizing the  automated operation of technical building equipment is rarely considered. The increasing complexity of building  technology, shortage of skilled workers, time pressure in  municipal commissioning processes and the high manual  effort required to check automation functions lead to  deficits in the quality of building automation. This motivates the use of automated certification of automation stations in existing buildings against user requirements and continuous monitoring of system performance. The article describes the procedure for checking building automation in existing buildings, documents results from 40 analyzed  properties and a comprehensive performance monitoring  of the technical building equipment.
