Different districts, the same goal: sustainable building and refurbishment for future-proof housing
The construction of new wooden buildings in Elstal in Brandenburg and the refurbishment of multi-storey 1960s buildings in the heart of Kreuzberg in Berlin – the two measures sound very different, but they have one major thing in common: both pursue the goal of sustainability and seek to reconcile environmental, economic and social aspects as best they possibly can.
The six- and eight-storey buildings of the Spring estate located between Franz-Künstler-Straße, Alexandrinenstraße, Neuenburger Straße and Alte Jakobstraße in Berlin-Kreuzberg were built in the 1960s. 1,136 apartments and nine commercial units – space totalling 69,360 sqm – have been undergoing refurbishment here since 2016. In addition to bathroom modernisation and pipework renovation in approximately half of the apartments, the focus is above all on energy-related refurbishment, the windows, and insulation of the external walls, the basements and the attics. The measures improved energy efficiency by an average of 53% to approximately 88 kWh/sqm per annum. This will cut carbon emissions by around 980 tonnes per annum – an average of 58%.
