dena offers the creation of refurbishment roadmaps for large building portfolios. This provides property operators with clear information on the long-term ecological and financial objectives they can achieve by making certain investments in buildings and construction technology.
As a basis for strategic action plans, Refurbishment Roadmaps help remove obstacles in the ongoing refurbishment of large building properties. dena has already prepared refurbishment roadmaps for residential and non-residential building portfolios, among others for the Institute of Federal Real Estate and the Brandenburgischer Landesbetrieb für Liegenschaften und Bauen. dena developed a refurbishment strategy for 150,000 residential units owned by Deutsche Annington (today: Vonovia) that also highlighted the social, economic and energy efficiency aspects.
The first step in developing a Refurbishment Roadmap is to collect detailed data on site. Possible refurbishment measures are weighted and a prioritised list prepared based on criteria defined by the client – for instance the targeted primary energy savings and the maximum investment volume. A schedule is then drafted for each phase of the refurbishment process.
