Haus Elisabeth in Lüdenscheid: Home game energy supply

Haus Elisabeth in Lüdenscheid used its renovation phase to invest in a cogeneration unit. Now the nursing home produces part of its energy itself, resulting in a positive outcome: In 2013, the home achieved a revenue surplus of more than 35,000 euro. An opportunity that is also available to many other nursing homes.

Things are much different in old age. Energy utilisation too – especially in nursing homes. Here, the heating is on around the clock. Large kitchens and laundries produce high peaks in electricity consumption. Then why not simply produce energy themselves? The directors of Haus Elisabeth nursing home in Lüdenscheid asked themselves this.

Engine for progress:

  • high economic potential
  • costs saving for the operator of the home and for the residents
  • highly transferable as it is easy to imitate

Expert personnel provided guidance and advice to the charitable church institution throughout the entire planning process.

No sooner said than done: During the renovation of the home, the parties responsible incorporated a cogeneration unit. The plant produces heat and electricity for the home all year round using gas. The operators can feed what is not consumed into the network and are compensated for this. This pays off: The directors of the home recorded a surplus of 35,000 euro due to the small power plant in 2013 alone.

An opportunity for many nursing homes, complex building structures are no problem

Others can do what the home in Lüdenscheid has done. Therefore, the nursing home is sharing its experiences with other interested parties. Energy-efficient cogeneration units are not used across the board in nursing homes yet. Many directors of homes are missing out on the opportunity to save energy costs. They could invest the money in other areas and strengthen their competitive position.
The Lüdenscheid project shows that complex building structures do not present an obstacle either: The nursing home buildings are in part up to 300 metres away from each other. Haus Elisabeth covers more than 7,000 square metres, including 48 apartments and 75 care places.
