Economy moves in
Complex requirements demand
particularly intelligent solutions. This is
why Siemens offers a comprehensive
system specially for hotels that fulfils
all these requirements – the GAMMA
instabus. It enables you to save on energy
and costs – without diminishing the
comfort of your guests.
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 guest rooms,
dining areas or conference rooms when
they are also in use. The room tempera-
ture can be controlled by motion sen-
sors, 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 is reduced or deacti-
vated altogether.
• At night, the heating is automatically
lowered, e.g. in guest rooms to sleep-
ing temperature. A guest can of course
change the temperature at any time or
turn off the heating, cooling and venti-
lation completely.
• In rooms that are temporarily unused,
as in the conference area, a “Central
off” setting can reduce heating, cool-
ing and ventilation to protection
mode.
Light and shade as it‘s needed
• In corridors or ablutions in particular,
the lighting is presence switched out-
side main usage times. During main us-
age times, the lighting is reduced to a
variable minimum level when nobody is
present. This achieves optimum
energy saving for a longer average life
of the lighting.
• Light and shade are controlled in public
rooms and guest rooms such that as far
as possible the available daylight can
be used without glare. Having the
light switched on and the blinds closed
is a situation that we avoid 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 automati-
cally according to the position of the
sun.
• A constant light regulation only per-
mits the amount of artificial light need-
ed in the room. Of course, you can al-
ways adjust the light manually to suit
your needs.
In corridors only the necessary lighting is pro-
vided by a presence dependent constant-lighting.
This cuts down on energy and costs.
