Cove.tool refers to the standard EN 15232 for simulating the effect of Building Energy Management Systems. The EN 15232 describes methods for evaluating the influence of building automation and technical building management on the energy consumption of buildings. The standard defines a structured list of building automation and technical building management functions. It provides a factor based method to achieve a first estimation on the influence of these functions on typical buildings and a detailed method for the evaluation of such influences on a particular building.

EN 15232 has defined different Building Automation and Control (BAC) efficiency classes. After a building has been equipped with building automation and control systems, it will be assigned one of these classes:

a) None: No building energy management system. This class refers to the ‘Class D’ of the EN 15232.
​
​ b) Simple: Adapting the operation of the building and technical systems to user needs. This class refers to the ‘Class C’ of the EN 15232.
​
​ c) Advanced: Optimizing the operation by tuning the different controllers, standard alarming and monitoring functions and more. This class refers to the ‘Class B’ of the EN 15232.

Examples of the control strategies included with each classes are included in the table below:
