A healthy economy
The complex requirements of a hospi-
tal operation demand particularly well
thought out solutions. In order to save
energy, simplify procedures and reduce
overheads, Siemens provides an integrat-
ed system with GAMMA ins tabus which
meets all these requirements.
Light and shade on demand
• Light and shade are controlled so that, as
far as possible, the available daylight is
used without glare. Having the light
switched on and the blinds closed is a
situation that is avoided as much as
possible. Electricity is saved and the air
conditioning system doesn‘t need to
struggle against sunlight and the heat
created by artificial lighting. To make this
happen, the blinds adjust automatically
according to the position of the sun.
• A constant light regulation auto-
matically supplies the room only with
the amount of artificial light needed,
e.g. 30 % instead of fully switched on,
and the lighting level is always
adequate. Of course, you can always
adjust the lighting manually to your
needs.
• In corridors, restrooms or lounges, the
lighting outside main usage times can
be presence-dependent. During main
usage times, the lighting is reduced to a
minimum brightness when the room is
unoccupied. This achieves optimum
energy saving for a longer average life
of the lighting.
Room temperature according to use
• Heating and cooling costs are a major
factor in a building‘s operating costs.
GAMMA instabus reduces these costs
significantly, by only fully heating,
cooling or ventilating patient rooms,
waiting areas and laboratories when
they are actually needed. The
room temperature can be controlled
by motion dectectors, room-based
utilization plans or manually.
• As long as windows are open, the
heating is lowered automatically to
frost protection level and the cooling
and ventilation are reduced or deacti-
vated altogether.
• In areas of the building that are
temporarily unused, a “Central off“
setting can reduce heating, cooling
and ventilation to protection mode.
More efficiency in building
management
• With its central visualization, GAMMA
instabus permits an up-to-date picture of
the whole building and the operation of
all building functions. This supports effi-
cient building management in hospitals.
• The connection to existing data net-
works (LAN and Internet) or a building
control system allows the building
management to spread across several
parts of a building or buildings. Even
distributed hospitals can be administered
optimally thanks to real-time status
information.
If a patient opens the window, the heating is
turned down automatically. This saves energy
and costs. On closing, the heating turns up again
automatically.
If the lighting in corridors and stairwells is
presence-dependent, permanent light can be
abandoned. This saves energy without loss of
security and comfort.
