Modern building installation enables a high degree of functionality and simultaneously complies with
increased security requirements. Due to the structured installation of the electrical components, it is
possible to carry out rapid planning, installation and commissioning as well as achieve cost benefits during
operation. With individual room control, potential savings of up to 25 % of the energy consumption can be
achieved.
The technical systems for control of the room temperature and air quality consume the largest share of
energy in a building. Accordingly, the largest savings can be made here. Mistaken or incorrect operation
can lead to expensive waste of energy. High levels of energy consumption are greatly reduced or avoided
by optimisation of a building with regard to the architecture, construction and installation engineering.
On a room level, the KNX intelligent installation systems support the user in optimisation of the energy
consumption and provide information to the installation engineering or the building control engineering for
optimisation of the setting parameters. By detecting the actual temperature value and specifying a
respective temperature setpoint with a control algorithm, the thermostat sends a control value to the
actuator, e.g. the Valve Drive Actuator VAA/S x.230.2.1. This controls an Electrothermal Valve Drive, e.g.
TSA/K. This on the other hand opens or closes a value of a heating or cooling unit, e.g. underfloor heating.
This then changes the room temperature. An additional presence detector used for control of the room
lighting can simultaneously switch the room thermostat to absent mode as soon as the room is unoccupied
for an extended period. Heating or cooling energy can be conserved in this way.
Practical experience has shown that the reduction of the room temperature by 1 °C can reduce the
consumption of heating energy by 6 %. If the room temperature is reduced by 3 °C during absence, 18 %
of the heating energy can be saved in a non-occupied room.
