EN 15232
“
Energy Performance of Buildings – Impact of Building Automation and Building Management
”
The EU Directive EPBD includes the standard EN15232, which contains the following:
A structured list of the control, BA and TGM functions that influence the energy efficiency of buildings.
A simplified method to obtain an initial assessment of the influence of these functions on the energy efficiency in typical buildings.
Energy efficiency classes of building automation
Class A:
High-energy efficiency room automation and networked
plants and services
Class B:
Optimal solutions for each plant or service, partially networked
Class C:
Standard room automation, reference document
Class D:
No room automation, not energy efficient
Room automation and its implementation is an important aspect
of the assessment!

Energy-saving potential
Savings with electrical energy (lighting/sun protection)
Energy-saving potential
Savings with thermal energy (heating/cooling)
Saving potential by retrofitting Class D in accordance with A
Saving potential by retrofitting Class C in accordance with A
Examples of essential measures for the EN 15232 rating:
Class C:
Central control of the room temperature
Lighting with manual setting/dimming
Simple sun-protection automation
Class A:
Energy-saving potential
The EN 15232 clearly shows for the first time and in a standardised form the enormous energy-saving potential that exists when
managing building technology systems. The amount of energy saved can vary for different building types using a range of user
profiles (EN 15217):
Networked temperature control for individual rooms
Light control in accordance with requirements
Networking of blinds and light control with heating,
ventilation and air-conditioning systems
For VAV: Load-dependent control
via an air quality sensor
