Aperfect place to heal

Hvidovre Hospital in Denmark

Officially opened in March 1976, Hvidovre Hospital in the Danish city of Hvidovre was built between 1968 and 1979. The four main buildings are just three stories high and placed in a park-like setting. Hvidovre Hospital is one of Denmark’s largest hospitals with more than 40,000 patients admitted each year.

Challenge

Siemens experts analyzed the 245,000 m2 hospital in detail and identified measures to reduce energy consumption and CO2 emissions. Since hospitals operate 24/7 and consume a great deal of power, they also offer a large potential for energy efficiency upgrades. The project had to be executed during normal operations.

Solution

The measures implemented at Hvidovre Hospital include expanding the photovoltaic system, installing geothermal storage systems and wind turbines, and modernizing the building management system.

 

This energy performance contracting project is the largest of its kind in Denmark. Siemens will finance the costs in advance, and Hvidovre Hospital has a payback period of ten years. The major facility improvement measures of the project include replacement of existing air handling units, installation of 14,770 LED light tubes, replacement of pumps, and migration of the existing building management system to Desigo with 4,500 I/O and 409 Total Room Automation (TRA) controllers. The project also includes renewable energy from five wind turbines, 1,500 kW of photovoltaics and borehole thermal energy storage (BTES).

Benefits

The hospital is able to reduce heat consumption by 41 percent and electricity consumption by 23 percent. On average, this results in energy savings of 33 percent. Furthermore, this project helps the customer to make real progress toward environmental goals within a short period of time.
