24.10 EN ISO 52120-1 (2022) Standard for building automation

The EN ISO 52120-1 standard, which replaces the old EN 15232-1 standard, focuses on the classification and assessment of building automation. The standard defines a catalogue of possible functions and functionality levels for building automation systems and introduces efficiency classes to assess the performance of these systems. The efficiency classes are linked to the achieved functionality levels, thus creating a clear reference framework for the assessment of energy saving potential.
