The History of Siemens Building Technologies

Siemens Building Technologies is an Operating Division of Siemens AG and was founded on October 1, 1998, through the acquisition of the industrial activities of Electrowatt Ltd. (Zurich, Switzerland), thus integrating and combining several decades of experience in building automation and fire safety. Electrowatt’s history dates back to its foundation in 1895 with a focus on power generation and distribution and respective engineering services. Its industrial arm was built in the second half of the 20th century by the acquisition of Cerberus Ltd. (Männedorf, Switzerland), a world leader in fire safety founded in 1940, and of Staefa Control System Ltd. (Stäfa, Switzerland), a leading European player in building automation, founded in 1962. In 1996, Electrowatt acquired Landis & Gyr Ltd. (Zug, Switzerland), founded in 1896, and merged this company’s building automation activities with Staefa Control System under the new name of Landis & Staefa.

Today, the Siemens Building Technologies Division consists of the Business Unit Control Products and Systems (CPS) and the Division Function Solution and Service Portfolio (SSP)

With the Business Unit CPS and the Division Function SSP the Siemens Building Technologies Division combines offerings for building security, life safety, building automation within one company as a service and system provider, and as a manufacturer of respective products. By virtue of the unique combination of these business sectors, the company occupies a leading position worldwide.
