Sustainable use of energy
Slashing electricity consumption
Saving energy with intelligent building systems
The cleanest electricity is always the electricity that’s not used at
all. The potential for reducing energy consumption and thus cutting
costs is particularly high in buildings, industrial production and
transportation. We provide technologies that match power con-
sumption to availability. For example, our demand management
systems are helping more and more consumers use power when
supplies are high and rates are low.
Our intelligent building technologies are boosting the energy effi-
ciency of residential and commercial buildings while enhancing
comfort and productivity for users. Comprising a wide range of
solutions and services, our building management systems control
everything from electrical installations and heating, ventilation and
air conditioning systems to lighting, access control, video surveil-
lance and fire safety solutions.
In the area of transportation, electric mobility is of major signif-
icance. Whether in buses, trains or cars, our electric motors are
about three times as efficient as internal combustion engines. And
transportation isn’t the only area in which electric motors are pro-
viding answers. They’re also optimally suited for use in industry,
where they power conveyor belts and pumps, for example. Electric
drive systems currently account for nearly two-thirds of industrial
power consumption, which our optimized drive solutions can slash
by up to %.
