rises. In contrast to window blinds, however, the
view to the outside is not restricted in the dark-
ened state and the daylight yield remains high.
The improved indoor climate is also reflected in
reduced energy requirements.
SAUTER using BACnet-MQTT gateway for
demand based light control
The challenge for SAUTER was to integrate the
control of the windows into Merck’s own app. IoT
data points were programmed for access, and
each of the eyrise control modules addresses
®
up to eight windows out of a total of 112. The
ecos504 automation station forms the BACnet-
MQTT gateway, allowing modular room automa-
tion with optimised energy consumption. A total
of 18,500 data points have been implemented in
the building. In addition to MQTT for the IoT con-
nection, numerous other communication stand-
ards are used: BACnet/IP (system- and manu-
facturer-independent) for laboratory control,
EnOcean for room operating units, DALI for the
lighting control and SMI for external sun shad-
ing. SAUTER fitted 11 cabinets in the technical
control centres for system automation and 30
cabinets on the different storeys for room auto-
mation. Modbus applications were also imple-
mented by SAUTER.
SAUTER’s modulo system formed the basis of
the system solution tailored to the center’s tech-
nical requirements. Decentralised room automa-
tion kept installation costs low. The integrated
solution and harmonised products (HVAC func- © Merck KGaA
tions, sun shading and lighting) also help reduce
emissions. In matters of building automation,
SAUTER Germany has been the go-to expert
for Merck since 2009. Since then, SAUTER has
been involved in around 40 of the customer’s
buildings at the Darmstadt site and, among other
things, has taken over the building automation of
the Merck Innovation Centre, which opened in
2018. Thomas Wosnitzka
