Healthy cost-effectiveness
The multi-faceted requirements of a rest
and nursing home demand specially
thought-through solutions. In order to
save energy, simplify procedures and re-
duce overheads, Siemens offers with its
GAMMA instabus building management
system a comprehensive system which
meets all these needs.
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.
• As long as windows are open, the
heating is lowered automatically for
frost protection and cooling and venti-
lation are reduced or switched off.
• Rooms or restrooms are only heated,
cooled or ventilated fully if they are
also in use. The room temperature can
be controlled by presence detectors,
according to times of use, according to
occupancy plans or manually.
• At night, in areas of the building which
are no longer in use, such as the dining
hall, the heating, cooling and ventila-
tion can be reduced automatically by
“central off”.
Light and shade as needed
• Solar protection which tracks the sun‘s
movement reduces direct or reflected
glare for visual or reading tasks – with
ideal use of daylight. As the angle of
the sun increases, blinds are opened
gradually and at the same time the pro-
portion of artificial light is reduced.
This produces appealing mood lighting
and saves energy.
• The automatic shade system controls
heat entry according to the time of year:
Venetian blinds reduce solar radiation in
summer and in winter, the sun‘s warmth
is used to the maximum. Heating, cooling
and ventilation costs will be reduced. And
the staff are freed from the task of raising
and lowering the blinds in every room.
• Constant light regulation ensures au-
tomatically that only the artificial light
needed is supplied as artificial light,
e. g. dimmed to 30 % instead of being
switched fully on. This means that the
lighting is always adequate. Naturally,
if need be, the constant light regulation
can be overridden manually at any time
and adjusted to the current situation
(e. g. turning the lights down for a pres-
entation).
• In corridors or restrooms, the lighting
can be switched off outside main usage
times depending on presence. During
main usage times, the lighting is turned
down to a variable minimum bright-
ness. In this way, optimum energy sav-
ing is achieved, with longer average life
of the lighting.
If a resident opens the window, the heating is
turned down automatically. This saves energy
and costs. When the window is closed, the
heating is turned up again automatically.
Constant light control ensures automatically
that only the required artificial light is supplied.
Energy consumption and costs will be reduced.
