Cutting costs through
energy efficiency
The best way to lower operating
costs is to consume less energy.
Intelligent building automation
technology from Siemens helps
reduce the energy use by as
much as 30 percent.
Achieving energy efficiency without
sacrificing comfort
Rising energy costs and government
regulations are not the only reasons
why people are rethinking their energy
consumption. Growing awareness of
climate change and dwindling resources
are other factors why energy efficiency
is becoming more and more important
in everyday life.
Buildings account for roughly 40 percent
of global energy consumption. Examples
include residential buildings, office and
commercial buildings as well as hotels,
shopping centers and industrial buildings.
Lowering energy consumption using intel-
ligent building automation is particularly
effective. Improvements to existing build-
ing automation systems often require little
investments and help save a significant
amount of energy, reduce CO
2
emissions
and shorten payback periods.
The building management systems from
Siemens make it possible to reach efficiency
class A under the European Standard
EN 15232. As a leading specialist in energy
efficiency in buildings, with more than
30 years of experience and an extensive
and harmonized portfolio of products,
systems and solutions, Siemens is the
ideal partner for optimizing efficiency.
