The Wohnungsgenossenschaft Neudietendorf e.G. relies on contracting and works together with Ohra Energie GmbH. The modern heating technology is supplied by the manufacturer Brötje. The aim of the modernization measure is to implement efficient heating systems and an easily calculable cost scenario for the existing residential and commercial buildings in the town in a total of three construction phases by the end of 2022.
For more than 15 years, the system has served the heating quarters of the Neudietendorf e.G. housing cooperative in the town of the same name. Now the old gas heating systems had to be replaced with newer, more contemporary versions. The cooperative has been using contracting for modernization projects since the 1990s. This energy concept offers advantages, especially for larger properties: All necessary lifecycle costs are covered and can therefore be calculated more easily by the owner.
“This model is interesting for our cooperative because our old heating systems are being renewed without this requiring a major investment for us in one fell swoop.”
Ohra Energie GmbH is on board as a partner for the current project, which plans to use gas condensing cascades from Brötje in the individual properties. The modernization measures already began at the end of 2019 and are scheduled for completion in the summer of 2022. The utility has already taken over the management of the first systems for 150 apartments at the beginning of 2021. The entire construction project was and will be implemented in occupied condition. A total of 17 gas condensing boilers are being used in the refurbishment project. The range includes boilers with outputs of 28 (38) kW up to a cascade system of 3 x 110 kW.
After completion of the refurbishment project, around 248 residential and commercial units will be supplied. In addition to the comfort provided by the modern heat generators, users will then also benefit from the maintenance and monitoring service, which guarantees a high level of reliability. Already now, all parties involved from Ohra Energie, the executing company Lang GmbH and August Brötje GmbH emphasize the good cooperation during planning and execution, the communication on eye level as well as the perfectly coordinated time management.
