Cleanvelope – PV and Building Greening Students Design Concepts of Refurbishment in Nuremburg

Krippner, R. / Flade, F.

A task of the future, with regard to the social challenges of the transformation of the energy system and the adaption to the climate change, is to upgrade the energy efficiency of old buildings. The EU has set itself the goal of making the building stock almost climate-neutral by 2050. A forward-looking approach is to combine building greening techniques and photovoltaics (PV), as a number of synergy effects can be expected here. A seminar in the master‘s programme at the Faculty of Architecture of Nuremburg Tech in summer semester 2019 examined how buildings can be upgraded between the conflicting priorities of building culture, renovation, solar technology and building greening. Using the example of the “Nordring“ quarter (12 multi-storey residential buildings built in 1959) in Nuremburg, renovation concepts with building greenery and especially photovoltaics were proposed, which, in addition to a design upgrade, demonstrate that both strategies complement each other effectively. In 20 projects, different approaches, from cautious intervention to strong transformation, were developed and constructively deepened. The results show an enormous potential for upgrading of the building environment and housing stock.
