Conclusion
The overall energy efficiency of a building can be increased significantly by working with control
experts right from the planning phase. This includes optimizing the hydraulic system, subdividing
heat and refrigeration producers according to partial load criteria, defining the control loops, and
interfacing heating, cooling, ventilation, sun protection and lighting systems at room level. To
ensure that energy-saving features yield long-term benefits, it makes sense to enhance control
systems with energy management features. This also allows malfunctions and faults to be
identified as early as possible.
The Desigo Building Automation System is part of Siemens’ Environmental Portfolio. In fiscal 2010,
revenue from the Portfolio totaled about €28 billion, making Siemens the world’s largest supplier of
ecofriendly technologies. In the same period, our products and solutions enabled customers to
reduce their carbon dioxide (CO
2
) emissions by 270 million tons, an amount equal to the total
annual CO
2
emissions of the megacities Hong Kong, London, New York, Tokyo, Delhi, and
Singapore.
