The city of Vellinge, Sweden
Building modernization with Energy Saving Performance Contracting
The city of Vellinge in southern Sweden has 33,000 inhabitants and owns real estate on a building area of over 100,000 m2.
Energy savings and cost reductions needed to be realized in 36 office buildings, schools, retirement homes, and swimming pools. The corresponding energy modernization measures were to be cost-neutral.
As a part of their Energy Saving Performance Contracting, Siemens equipped the real estate with the intelligent building automation and control system Desigo PX and Desigo Insight. The manufacturer’s investment in the modernization will be refinanced through the contractually guaranteed energy cost savings within ten years.
In addition, Siemens is responsible for energy monitoring and controlling of the systems. The Advantage Operation Center in Malmö monitors all measurement points of energy flows and analyzes all information necessary for efficiency evaluation and enhancement.
Thanks to Desigo PX and Desigo Insight, the municipal buildings are now extremely energy-efficient, and their CO2 emissions have been significantly decreased. With an Energy Saving Performance Contract, energy savings are guaranteed and finance the modernization. Thanks to energy monitoring and controlling, potential for additional energy savings can be continuously found and tapped.
The energy-saving modernization was awarded by the European Energy Service Initiative (EESI) as the “Best Energy Service Project.” Thereby, Siemens received one of EESI’s “European Energy Service Awards” for the sixth year running.
