4 The EN 15232 standard in detail
EN 15232 makes it possible to qualify and quantify the benefits of building automation and control
systems. The entire standard is based on building simulations using pre-defined building automation
and control functions.
Parts of the standard can be used directly as a tool to qualify the energy efficiency of building
automation and control projects. It is also planned to assign projects to one of the standard energy
efficiency classes A, B, C or D.
Energy flow model
The energy needs of various building models with differing BAC and TBM functions are calculated
with the help of simulations. Various energy flow models for the basis, e.g. Energy flow model for
thermal conditioning of a building:
