Energy-optimised construction in refurbishment
Old buildings also have a future, because the greatest potential for energy savings is in the building’s fabric. The implementation of new concepts, materials and technologies in refurbishment is demonstrated in a whole range of exemplary refurbishment projects. Whether a large residential complex, a small residential building, office building or hall of residence, data acquired from scientific evaluation makes these pilot applications into models for consistent building refurbishment. Each project description is updated on an ongoing basis, and follows the project through its phases, from "planned", "refurbished", "in operation" and "evaluated", through to "optimised".
Special buildings
The Luitpoldhaus, erected in 1911 and reconstructed in the 1950s after having been largely destroyed, will now be refurbished. The project will merge the various library functions at this central location in Nuremberg. To this end, the buildings will also be converted and extended. The storage of manuscripts, incunabula, prints and maps from the Middle Ages requires sophisticated air-conditioned rooms.

Small residential buildings
In Hofheim am Taunus, three structurally identical double-family houses were refurbished according to different energy standards, allowing for a direct comparison. The pre-fabricated, storey-high insulating elements represent a new kind of facade heat insulation. They are thinner than the traditional insulation due to their integrated vacuum panels and do not stick so far out onto the public pavement.

Office buildings
The headquarters of the Kreditanstalt für Wiederaufbau (KfW) was built in the late 1960s as a group of office towers in Frankfurt’s Westend.In recent times, the building was starting to look somewhat down at heel and therefore the owner decided that it needed to undergo radical modernisation – only the load-bearing framework from the original building remained intact. This enabled the provision of daylight, fresh air, heat and cooling to be considerably improved and, above all, to be carried out in a much more energy-efficient way.

Office buildings
Built in 1968, the building was beginning to look very shabby and the facades and roofs were in urgent need of refurbishment since, as part of administrative reforms, it was intended to change the use of the building. Following completion of the rebuilding works on a very tight budget in 2006, the refurbished building now houses the vehicles for the city’s waste disposal services on the lower two floors and the administration in the upper two stories.

Office buildings
The commercial property from the 1970s ought to be radically modernised. The low-rise building for around 120 staff had the same weaknesses as many buildings from this period: high energy consumption, inadequate daylight provision, poor air quality and thermally uncomfortable in summer and winter.
